Auxilliary ventillation
 

I have just treated myself to an 02 3.0D Sport and so far I'm really liking it.

Can anyone help with the following though?

Auxilliary ventillation. I'm I getting this wrong or should this not warm the car up in the morning when you set the timers to come on? With the timers set the fan starts but only luke warm air comes out. The car doesn't seem to want to let me turn it on 'direct' neither. The manual reads as if you should be able to turn on the heating with it if it's less then 16 degrees outside. Am I missing something with this?

On a seperate note. Is it possible to override the TV so the wife can watch it in the passenger seat when we're driving along?

Any help would be great. Thanks :thumbup:

I have the same issue with the Aux ventillation. I can see the heater outlet under the left of the car so I know it is there. The timers only seem to turn on the fresh air intake (made for cooling a little in the summer) not the heater. I note on mine that according to the manual there should be a 'heat' option on the obc but I seem to have a 'stopwatch' instead. There aparently is a remote control option for the heater / Aux which would be the way to go. The First trip back to the dealer next week, so will ask them then.
No TV on mine.

The aux ventilation is not meant to either heat the car nor cool it per se. The heat function only works as a temporary function after the car has been running. The heat comes from heat generated by the engine. For example, you have been driving around for awhile, stop to pop into a shop and you want to keep the car warm for a short period of time. That will work. Likewise, the cool function only serves to suck out hot air in the car and keep the temperature lower than if the interior were allowed to heat soak.

You cannot heat up the car as you are wanting nor cool it with a/c without the engine running.

Oh, :welcome:.

Someone feel free to correct me if my recollection is wrong.

There are a few threads on this. With the aux heater you CAN pre warm the car on a morning say using a remote control. The aux ventilation is different and can COOL the car under timed conditions. Read your manual that came with the car or ask your dealer. the odds are if you had Aux heater installed then you would have got a remote control for it with your car (different to the remote keys you have).

Re TV, yes you can overide it, I did mine. You need a TV IN MOTION lead or similar. Look on ebay or search in google. Make sure you get one with the correct connectors on it and NOT the one you have to hard wire yourself. They are dead easy to install.

Me too!
 

I have both the aux heating and cooling option with the seperate remote control. During summer, I experimented a couple of times with the remote. The problem I had was that the car would only heat the car no matter what the outside temperature was.

I just tried the remote again (its 12 degrees outside) and the car heats up. During the really hot summer days, I tried the same thing and I would get back to the car and it would be a suana!

I'm taking the X in for its first service and will hound the dealership for answers. Will keep you guys posted.

the remote is ONLY for the heater, you have to set the timers on the computer for the ventilation option.

Interesting. What does the remote look like? As far as I know, the option you are describing was not offered here in North America. I thought the original post was about the standard venting feature. (See Page 112 of 2002 owner's manual.)

Had the X back at the dealer today (for the first time :-) and asked if the aux heater could be activated as I was missing the 'heat' option on the computer but appeared to have the heater fitted (see picture!). Spoke with the engineer (who had a German accent which is a good sign!). He said this was not the aux heater, but just a diesel preheater which will activate in very cold conditions (like never in Australia). Hence it may look like a standard option on all the diesel models but is a different heater.
Not totally convinced, but winter is over anyway ;-)

I am not sure how true this is but worth asking the question to your dealer! This is what i found out all diesels have all the parts as standard but in europe you have to buy the key to make the heater work which i can take a picture of if you like but i was told by BMW UK that US cars have to be re programed with the bmw computer and this will make them work how true this is dont know but this is what Iwas told when I tried to get mine activated for free because the salesman told me my car would have this feature as standard in the end the gave me the extra parts for free :-) You can by the kit from webasto which is not that expensive if you have the heater already there which is in the engine bay on the right hand side at the back if you are standing at the front of the car again I can take pictures for you

What parts were you given?
Was it just the remote, or are there other bits to make it all work?

X5 Sport - yes - may need a pic. I cant make much sense of the right rear of the engine bay (image attached). Aftermarket remote would be a nice option if indeed the required heater bits were there.
DS

Am in the uk. I have the 3.0D sport and i know the heater is already there. Its a preheater to help start the car in cold weather!

So am i right in assuming that i can get a "key" or remote which will make this all work??

Come on then.. am waiting.. tell me what i need and where i can get it from??

http://www.webasto.us/am/en/am_rv_heaters_821.html

Have a look at this site might make everything a bit clearer I have the BMW remote which is slightly different to the one on this site.

Like i said before. Like many other X5 Diesel drivers we have the webasto preheater already installed but this option is not live on the nav screen or anywhere else on the car.

How do we activate it? is it just a remote controll we need? surely its more complicated than that

Yes you need a control unit ariel and remote can buy from BMW but webasto do the same unit and proberly will be cheaper.Speak to paul at webasto in the uk he is so helpfull.

Thanks for that.

Do you have any contact details for this Paul at webasto in UK?
Any idea on costs?

Thanks again. If not too much money i think i will get it fitted.. considering winter is nearly upon us now! :)

Just had email back from Webasto! Please read! It appears to be possible but only BMW supply the part! :( they just want to steal more of my money! Any one know if i can buy it seperatly and is it easy DIY job?


As you are aware, the BMW X5d is fitted with the Webasto Thermo Top C
fuel-burning heater as standard, which is used as a supplementary heater. In
this application, the Webasto heater only operates when the engine is running
and the outside temperature is below 5°C. In conjunction with BMW GB, we have
developed a simple upgrade, which includes the addition of a simple electrical
interface harness which will switch the heater on independently.

The parked car heater is started by a remote control device and warms the
coolant independently from the vehicle's engine.

The vehicle's blower system takes the warm air into the cabin and, at the same
time, pre-heats the engine.

Once this upgrade has been installed, it will provide pre-heating for your
vehicle prior to commencing your journey. Some of the benefits associated with
such a system are as follows:

· Warmth and comfort of a pre-heated interior - a centrally heated interior.
· Screen defrost and demist - increase safety with a safer clearer vision
through the windscreen at the start of your journey.
· Pre-heated engine - no more cold starts/easier starting.
· A pre-warmed engine - a better engine response from cold.
· Reduced engine wear
· Reduced engine emissions - lower emissions from a preheated engine.

"Just drive off straight away and enjoy your journey."

The standard installation includes full system integration with the parking
heater controlled by a Telestart Remote Control.
This allows switching on and off of the system by a remote control handset with
a range of 600 metres.

In the UK, this accessory is exclusively offered by official BMW Dealerships
under the following BMW Part Number : 95.06.0.000.010, therefore you should
contact your local BMW Dealer in order to obtain pricing.

You can fit yourself is quite easy

x5 sport, can yuo please post some pics? cheers mate

Key Picture
 

Here is what the key loocks like that you get if you order aux heat not from the factory ie as retro fit.If you get it put on the car as part of your order you get a BMW logo on it too it also works slightly better some thing to do with the plumbing in and using antifreeze. I will try and take some more pics over the weekend of the bits in the car

Here is the Key

pics
 

Took some pics of the remote, screen with active function and the webasto heater by the engine.

Turns out the ventilating option doesn't put on the AC. Pretty useless if you ask me. Just don't see the point :dunno:

The remote only put on the webasto heater no matter the outside temperature. Its getting chillier over here, so will put this baby to the ttest.

Has anybody in the UK contacted BMW parts and got a price for the part 95.06.0.000.010 (the remote kit for the heater)? I just called mine but theyre closed. I want to know how much this add on is because I think this would be a great addition now that Winter is around the corner.

Adrian keep me posted on price etc. Want to know if its an easy install aswell.

Right, I called my local BMW and the part number does exist on their system, it comes up as PK HEATING. Presumably it means Parking heater or similar. The cost is £389 incl VAT so i`ve ordered one. They are due in tomorrow (26/10/05) in germany and then will be shipped out to me so it`ll be about a week I think before it arrives. I asked parts if it was a dealer fit part but he said he doesnt think so as the system doesnt say so.. When it comes I`ll have a go at fitting it. Fingers crossed.

I can't believe how helpful you have all been. Thanks very much!
I've had my car in for a service at the dealer and asked them to check it out. They told me that there is a problem with the heater and it is booked back in this Friday (28th). I have read the manual that came with the car and you all seem to be on the right wavelength. It does read as though all diesel cars have got the heater installed to help heat the car up after setting off for the first time. I did not get a remote control for the car though and I am wondering if this is needed to make it work.
After the car has gone in I'll let you know the outcome.
Thanks again.

Finally got my Webasto remote kit and will be fitting it later or tomorrow depending on the weather. FYI, in the box you get a black receiver module which mounts in the boot by the battery (where the TV mod and other things are), there is a connector in the wiring loom to the right of the battery which links to the new receiver which connects it to the Kbus (the instructions say). You get a remote control with ON and OFF buttons. Once the remote is programmed to the car (fuse removal procedure and then re instertion whilst pressing buttons etc), you can turn heating on and off remotely. The remote also gets signals from the car too to confirm whether the car heard your request etc. Finally you can program the remote to turn on either the heating OR cooling and also for how long it should run.. More later when it`s installed.

Sounds good! Keep us posted :)

All done, the install went well. The only confusing bit was where the instructions said I needed to use an adaptor cable (supplied) but the car actually had the right connector already so I didnt need the adaptor. The install was easy, the box installed in the boot by the rest of the electronics which are by the battery. The antenna sticks to the rear side glass, just a black rectangle which doesnt look out of place. Powered it all up, programmed the remote as per instructions and tested, I knew it was working because I could smell like a parafin smell but I couldn`t hear anything until I put my ear to the grille at the front of the car.

Superb upgrade and highly recommended.

If anybody needs help during install please PM me and I`ll try my best but it really is quite easy.

Excellent! Glad it all went in OK.
Another mod to add to my list :D

Got any pics of the install?

Also, would it be possible for you to post the instructions somewhere?

Sorry, it was freezing when I installed it and I just wanted to get it over with. I`ll explain a little more.

The antenna sticks to the rear right little window, just overlapping the black band around the glass, looks quite neat there.

The reciever has self adhesive tape which when peeled allows you to stick the little black box upside down (with two wires already connected at this point) to the wall of the boot area where the battery goes.

The antenna cable routes through the plastic panel by the window and from then on is not seen, it goes over to the fuse box and then cable ties along the rest of the cables in to the battery area where it connects to the receiver.

That`s about it really, you have to pull out the second to last 5amp fuse from the rear fuse box for 5 seconds, then plug it back in a wait 5 seconds and then press the OFF button on the new remote for 1 second to program the new remote to the system. You also do this with up to 2 more spare remotes if you have them.

There are actually 3 instruction books, one is a small portable one, the other is a few printed sheets with pretty good UK install instructions on and the third is a useless larger manual with loads of different languages in it.

I`ll have to scan the install instructions later and put them on here for you.
Hope the spelling is ok, I`m just hammering this out as it`s fresh in my memory.

clarification
 

Sorry to ask this again, but:

Will this mod only work for a diesel vehicle?

I have an X5 4.4i and I'd love to put this in.

thanks for the help.

navin

Man, thats weak, I have to go INSIDE of the car to turn on the aux. cooling and heating and set it to a certain time to turn on:(

I`ve heard that you cant aftermarket the Webasto on to a petrol engine, but if you ordered it when you bought the car then you can have it. You can only add the mod on to a diesel because the diesels always have the Webasto heater fitted even if you dont have the remote option. The additional heater is needed to warm the engine faster because they take ages to get warm on their own.

Also somebody said on here you could only control the heater with the remote, it`s not true. You can program the remote for the summer too so that it just turns on the vents instead. This way you can at least get some air moving in the car before you need to get in it.

Adrian b

Can you answer a question for me on your nav screen does it say Aux Vent or does it say heating ? As in the pic posted earlier in this thread

Thanks

It shows 'Aux Ventilation'

Thanks mate as I thought might of had some thing missing since and sinse I got the car back from the re spray it is not working anymore :-(

great work adrian.b!!! and thanks for the explanation too. so J385 does the trick, right?

I`m lost here, what does J385 mean?
This thread is old so you`ll have to refresh my ageing memory (33yrs and counting).

sorry, i don't have the pound on my keyboard. i meant about 400 pound sterling is the cost for the pack.

Yup, that`s about it in total for everything you need.

I think that there is some confusion here!
On early X53.0Ds the aux heater is always fitted, but there is a bar on making it work from the tv screen.
This heater heats the interior NOT the engine.
In 2003 I had a fight with BMW GB, and they reprogrammed it to work fully without charge.
Later X5s do not have this "bar".
Incidentally, the ticking noise under the lh front is this heater, NOT a sticking relay.
The remote control is a sepatate issue.
Finally, this aux heater is not very effective, so I wouldn't bother too much if it dosn't work. Idling the engine for 5 mins before setting off has a much greater effect on comfort.

Only just found this thread which goes some way to explain something that's been puzzling me since I got the car. But can you explain when this 'bar' was removed and is it possible to remove it with a laptop connected to the OBD port?

Does that then show in the Nav screen?

It's a lot of money to find it doesn't really work. Could adrian.b comment on the real effectiveness of the heater?

Dont know anything about a bar, sorry. I always had an auxilary ventilation entry on the OBC but didnt use it much. As far as I know all X5 3.d cars have the Webasto engine pre heater and in fact it is always used in cold conditions whether you want it to or not, the car chooses. I was told they were there to speed up the engine heat up process so that the heaters would work faster.

Anyway I bought the remote control module so that I could remotely warm the car up 30 mins before I plan to use it and also defrost the car on a frosty day. This simply turns the pre heater on, it warms the coolant in the engine and when it`s warm enough, the car puts the internal blowers on to warm the interior. The heater is VERY effective as it burns diesel in a seperate burner and gets very hot. We use it all the time but beware, it drains the battery a lot. We have had to learn to make sure the car gets good runs/charges in the winter so that we can use the pre heater as we need to. (a few flat batteries tought us this lesson).

Hope this helps.

The aux heater heats air that is routed directly into the interior. I DOES NOT preheat the coolant.
On early UK delivery X5s this heater is fitted, but innactive. On all facelift X5s, it is active.
I'm not sure when the changeover was made.
Mine was activated in 2003 by the dealer after no small struggle because BMW UK said it was illegal to use it in UK. Their reason was that it could pollute the air in an enclosed garage. True.
However, I pointed out to them that LandRover used axactly the same heater, and it was active. BMW then gave the dealer details of how to make it work, and it did!
I guess that this followed through to all UK delivery X5s being delivered with a fully working preheater.
The aux heater cuts out when the temperature in the car is about 15deg.
You'll have to ask a dealer to reprogramme the car to make the heater work if it does not switch on automatically when you start the car at temps below +15deg. This reprogramme also activated the screen controls which prior to this permitted only the venilation mode, not aux heat......in fact, I guess that you can tell if the aux heater programme permits its operation by looking at the options on the screen. If no AUX heat offered, its not going to work.
The remote is a separate issue. It starts up the heater from a distance. However, simply installing this option will not neccessarily make the heater work automatically when it's cold in the car, nor allow you to programe the heater from the screen
If yourt aux heater is not active, it's well worth getting it sorted.
The remote is ok, as is programming the aux heater to start on a timer before you reach it, but in low temperatures, I'm in the European mountains all winter, running the engine for 5 mins before seting off is just as effective, and does not deplete the battery.
Phew

If it doesnt heat the coolant, then can you explain why my engine temperature guage is between cold and half way when I start the car on a cold morning after using the pre heater for 30 mins? And it only gets hotter (i.e. it doesnt drop straight away once the engine starts cirulating the water, it simply carrys on getting up to normal running temp)

Have a look here http://www.webasto.co.uk/am/en/am_automobile_3177.html

Read the part about the pre heated engine. I can only assume that the coolant is cirulated whilst the heat is applied to the engine, which in turn passes the coolant in to the cabin radiator which then allows the fans to blow air through it and thus warm the car. Anyway it warms the engine and the interior enough to make the leather seats bearable when it`s -5 outside.

Sorry to keep posting but I had to find this just to satisfy myself. The Webasto DOES heat the coolant.

http://www.wohlfuehlklima.de/en-gb/p...rmo-top-c.html

How your Webasto parking heater works
The water circuit is heated and pre-heats the engine. The heat is introduced into the heating and ventilation system. Snow and ice melt. The engine starts with no problems. The car is cosy and warm and you have a clear view from the start.

This is all REALLY interesting as I had assumed that the equivalent of a retrofit was economically impossible. But...

adrian.b, can you programme the heater with a timer via the OBC screen?

It seems to me that there are 2 methods of operation, via the screen and/or via the remote, but the former is only possible if the aforementioned 'bar' has been removed, otherwise heating control is limited to the remote.

john4231618, I would prefer to use the aux heater than simply running the car since while doing that the car is very vulnerable, unlocked, keys in and running - very convenient for the light-fingered. Also, if the build up of fumes in a garage is of concern, then running a 3 litre engine will create the problem far quicker. I am also keen to have control by timer and by remote - beats having to go out and start the car myself:-)

Then there's the issue of having such a desirable option already fitted to the car but currently I cannot make use of it.

Has anyone any idea if the re-programming to remove the 'bar' and allow heater control by timer can be done via laptop, i.e. avoiding the necessity of involving the dealer and the inevitable cost? £390 just for a remote is already stretching the bounds of acceptability.

The wife is out in the car at the mo, but I`m sure I can set TWO timers on the OBC for the heater and just blown air without heat.

I`m pretty sure a retro fit is very possible, but as mine already had one I didnt need to worry about that.

£390 isnt just for the remote, you have to install the remote reciever in to the electrics area in the boot under the spare and then route and stick an antenna on to one of the rear windows (usualy right hand side rear window).

Also you can program the remote to COOL the car in the summer months instead of heat it. It simply blows cold air from outisde (or cooler anyway) in to the cabin, it doesnt turn on air con etc.

Hope this helps.

From your earlier posts I understood that your screen just displays 'Aux Ventilation' and no mention of heating. This would indicate that it has no knowledge of the heating option. Although it appears that a BMW dealer can actually enable this, I would be interested to know however if you can set up timers for the heater without any further intervention.

I checked today and I do have the small exhaust pipe under the car, so I also definitely have the heater and just need to enable its control.

I realise that £390 isn't just the actual remote, but it's a simple remote system add-on and as such it's a steep price and now I know it's possible, I cannot deny myself:-)

X5 3.0D 2004
The remote installed in this car is the Webasto Telestart T70.
If I would have to buy a new remote I would go for the T100.
Just over 300 euros on eBay.

Do you have any ideas on how to interface this to the X5?

If the car is pre-wired for a remote it's easy.
Kind of plug&play.
Believe Adrian.B did the install himself.
Still, you would probably have the X connected to a BMW computer to tell the system that it has aux heating installed.
That's in case you don't have the aux heating option on your screen .

The cheaper T70 remote control is one-way so you'll never sure whether the heater was activated.
Others, like the HTM100 are 2-way.
This HTM100 will even show you the interiors temperature!

My question was directed at the HTM100 install. The T70 will plug strsight in as adrian.b has described, it is after all the BMW part. But what about the HTM100? Neither this nor the X5 were designed to work together, how would they connect, or would it genuinely be as straightforward as for the T70?

On a German Webasto page they say: "Alle Bedienelemente können miteinander kombiniert und aufgerüstet werden".
To me this looks as if all remotes are interchangeable.
The T80 and T91 are also 2-way remotes (reporting back), the T70 is not.
Another link.
On this realoem.com link you can see that BMW uses the T90 and the T100.

If you don't have the aux heater option in your menu be carefull, I do believe you need an electric waterpump to use it when the car is parked.
If the heater is installed without the pump it will just fire up if you start the car and the oat is below a certain value (like 7 degrees).
It would just help to heat up the coolant quicker as otherwise it might take a while before it feels cosey inside.
It's a very efficient diesel engine :thumbup:

Conflicting information as always:-(

Those links are really interesting Eric as I received a reply from Webasto stating that the HTM100 CANNOT be used with my X5 (maybe BMWs in general) as they are programmed to only heat for 30 minues and then stop, whereas the HtM100 would try to keep going until the selected temperature was reached.

I can see his point, but I wouldn't have thought that precluded any possibility of using the HTM100. I will tackle him further about this.

However, your mention of the water pump raises another question, similar to the point raised by my dealer when I requested they 'enable' the heating feature on the car computer. They said it would heat the water, but not heat the car.

A question for adrian.b. (sorry, but you're the main source right now as you've done the upgrade).

If you set the timer for Aux. heating, does it actually operate the fan, so the car is warmed inside, or does it just mean the water is heated so you can immediately use the fan when you get in?

Presumably the situation is the same when using the remote?

My dealer will 'enable' the heating system today, so i guess I'll find out, but they are charging to do it . No question that BMW would cover it, even when I pointed out that they had done so in the past for other cars. But I'm not going to argue as in fairness, those cars were probably still in warrantly and in any case right now I need all of BMW UK's goodwill for my more expensive steering column adj. problem.

I guess the big question is, has anyone fited an HTM100 to an X5?

Hello
Strangely I have only just found this thread which is odd considering how much research I have done on the matter of the auxiliary/parking heater recently....

Anyway, I have become (not really by choice) quite an expert on these heaters. I have a 2002 X5 3.0D which came with the Webasto Thermotop diesel auxiliary heater as standard (I say Auxiliary because BMW use this term to describe the heater when it is fitted as standard and only comes on when the car is started and the outside temperature is below +6 and coolant is below +60 celcius - I think this heater was fitted to all UK/EU 3.0D's).

I decided to upgrade the heater to a parking heater (which is the term BMW use when the car has been programmed to turn on the standard heater from the Bordmonitor or via the optional remote - T60 before 2001/T70 after 2001). My dealer sold me an upgrade kit for the coolant water piping which is a bypass operated by a solenoid valve and controlled by the cars heater/fan/AC control unit. This bypass became standard in 2003 because the car will only allow the heater (whether aux. or parking) to run for 30 minutes and in extreme low temperatures they found that 30 minutes was not enough to warm the engine block and the cabin. The bypass only allows coolant to flow though the diesel heater and the cars cabin heating circuit. I bought the remote control (T70) antenna and tranceiver unit off Ebay. I fitted the whole lot and then took the car to the dealer to have it programmed. They promptly discovered that my diesel heater was faulty and probably hadn't worked for some time. I then bought a replacement heater off Ebay, fitted it, confirmed on a cold morning that it was working correctly as an auxiliary heater and went back to the dealer.

However....they still cannot get it to work as a parking heater. When the heater is activated from the Bordmonitor or from the remote it starts and runs for about a minute and then shuts down. I have had a long conversation with Paul at Webasto and exchanged a few emails and he is convinced the problem is not with the heater as he feels the heater is doing what it is supposed to, and the problem is with the heater/AC contoller in the car. The start procedure for the heater when activated as a parking heater is as follows:
1. The heater receives a start signal from bordmonitor or remote.
2. It starts up and does an internal check, a check to see if its fuel pump is working and if the water circulation pump (for the coolant) is working.
3. If all is good it requests a run 'permission' from the cars heater/AC controller.
4. Cars heater/AC controller then checks battery voltage and fuel level and if both are OK it turns on the fans inside the car, and sends a run 'confirmation' to the heater and the heater runs for the next 30 minutes.
5. The heater will try this 'permission' request up to three times.

I think my problem is that the heater is not receiving the run 'confirmation' from the car and after 3 tries goes into shutdown.

I apologize for the long post but would really appreciate any advice. We've had quite a mild winter here in Holland this year and probably won't need the parking heater, so it's more about solving the problem now....lol

I have now had my ('04) X5 3.0d 're-programmed' by the dealer and although previously the screen only offered 'Aux Ventilation', it now displays 'Aux Heating/Ventilation' (maybe words a bit shortened). However, it's not been very cold since then and not actually used it. I must check it out.

Scaramouche, I assume the dealer programed your car like mine so it now offers the Heating option? Was their attempt maybe incomplete so it's not been fully set to use the heating?

I've not yet got to the bottom of whether the HTM100 could be made to work. Has anyone got one of these working with the X5?

UKenGB,
The dealer insists that they programmed my car correctly and when my car came back from being re-programmed the Bordmonitor screen option now shows aux. heating/ventilation as yours now does. In that menu you should now have 2 timer settings, a direct mode for ventilation and a new direct mode for heating. Choosing direct heating mode will turn the parking heater on immediately (and the fan inside the car) or you can set the time using the timers and the parking heater and interior fan will come on at that set time.

All that seems to work on my car and either method will initiate a startup of the parking heater....but it then goes into it's shutdown cycle after 30secs to a minute.

I would really appreciate if you can check if yours does work and if it does, I would be very greatfull if you could possibly pop the heater/AC control out of your dash (if you stick a blunt butter knife in next to it, it will come out very easily with no risk of damage) and let me know the BMW part number on it. After looking at the ETK, it seems that there are different part numbers for these units if you have the parking heater fitted. I'm thinking this might be my problem. Hey, I'll grasp at any straw....

I did put the issue of the heater/AC contol part numbers to the dealer and they consulted BMW Holland and both admit that it could be the problem but are not sure. A somewhat dissapointing response...

As for your concerns about the circulating water pump in your car, I'm fairly sure you would have it - the pumps seem to have been fitted as standard to all the UK/EU 3.0D's. It's mounted low down on the left front of the car, next to the radiator reservoir. If you don't have it, you will not be able to use the diesel heater as a parking heater because without water circulating through the heater, it will shut down due to over-temperature. Actually it won't even start as the heater looks for the pump before starting.

With the T100, I'm fairly sure it will work as Eric Le Baron has shown it is included in the ETK. However, I don't know if you will have all it's functionality. There is only a single wire that leads from the remote tranceiver unit to the heater and all that the heater is capable of doing is receiving the 12 volt signal that is sent down that wire when you push the button on the remote. I don't believe there is any feedback from the heater to the tranceiver. I don't think you will really be able to control how long the heater runs for or control the cabin temperature. The WDS shows the same connections between the remote tranceiver and the heater for all X5 model years, so it's not even as though it might be different on later models. I think the T80 is about as advanced as you can use, it will at least tell you if the car has received your start signal. (And its half the price of the T100)

Adrian, are you sure about this?

When setting the Timers, they seem to automatically heat or vent depending on the outside temp. Is it possible that if you use the remote on a hot day it will in fact vent and not heat?

UKenGB,

It is rumored that the remote can be programmed by the user to vent or heat, although looking at the wiring diagram for this system, I have my doubts. The timers can be programmed to heat or vent but it needs to be done by the dealer. I would think that as you have now had your car programmed for the parking heater, your timers will only heat regardless of outside temperature (same as mine). If this is the case, the only way you can activate the ventilation from inside the car is by selecting 'Direct Mode' on the Bordmonitor.

Things are not as they first appear :confused:

Having sat in the car and played with the options for a while, my conclusion is that...

When a Timer is set, it will Heat or Ventilate depending on whether the temperature is below or above 16 deg. respectively.

Once key is in position 2 Direct control of Heating is disabled. When the engine starts, Ventilation is also disabled.

But now the fun starts.

My Heating doesn't work AT ALL. If I use Direct to start Heating, the red indicator beside the RH control knob flashes, but nothing else happens. If I set a timer, the red light starts to flash at the set time, IOW the timer is working and activates the Heating, but that's not actually working.

AFAICT I have the water pump fitted, I can see it in front of and below the actual heater, so why does it not start? Sigh.

As regards Telestart remotes, I am still looking into the HTM100. I can't really see why it wouldn't work. Any timings can be calculated within the remote or its receiver/control box. The only thing I'm not sure about is the interior temp of the car. Does it need to get that from the car? If that's the case and it cannot be interfaced into the X5, then forget the HTM100. But maybe it has its own sensor?

There are various other remotes, just 2 button, such as the T80,90 and 91 and they all claim to have feedback from the car to indicate the heater is on, but they only have a simple LED, same as the T70 on which it flashes when you use it to tell you the car has heard the request. So is this any different in the T80 and above? Or are the T70 and T80 actually the same, but they call it the 70 when it an OEM product?

I'm interested to hear that the timers will heat below 16 deg and vent above 16 deg. I had originally thought that was the way they were supposed to work but was told differently by my dealer. (See my post above)

As to why nothing happens when when you activate the heater....Assuming your battery is charged and your fuel reserve light is not on.

The heater might have a fault lock out. Try activating the heater and then removing the heater fuse (Its in the glove compartment but I can't remember the number - I think it's marked 'Standheizung'), waiting for about 20 seconds and then replacing it.

BTW, have you confirmed that the heater comes on when you start the car and outside temp is below +6 and coolant is below +60 deg?

Ah, don't get too excited. There was some assumption in that diagnosis. When setting a Timer, there is no way to specify whether it Heats or Vents, but the manual is quite specific that heating only works below 16 and ventilation only works above 16. It is INCONCEIVABLE that BMW would have designed this so that you had to have the dealer re-program the system twice a year (surely?) and there is NO mention in the manual of this being fixed by the dealer. It would therefore seem logical to assume that the system does what is required based on the temperature.

I guess I will find out when it warms up.

The actual heater should receive a 12v signal (on pin 1 I think) and it is this that tells it to start. Since yours does start, it must be getting that 12v signal initially. But have you ascertained what occurs once it is running. If that pin drops to 0v, the heater will shut down. So you need to test that and see what happens. If the 12v is cut off, then you know that it is the control systems that are wrong, but if the 12v remains and it still shuts down, then it looks like it is the heater.

Have you done this test?

I don't think the 12v signal is supposed to be constant while the heater is running. It is only present to initiate the start-up sequence for the heater when using the remote.

When the heater is activated by the timers or the 'Direct mode' on the bordmonitor there is no 12v signal transmitted to the heater through the white/green wire which you correctly noted does go to pin 1 on the X764 connector. In this case the heater receives it's start signal through the I-bus connection on pin 2.

I'm fairly sure my problem is with the run 'confirmation' the heater should be receiving though the I-bus from the heater/AC controller. The heater/AC controller should also activate the bypass solenoid in the coolant circuit that I fitted and it doesn't do that either.

I have finally found what I think is the correct heater/AC controller for the X5 with parking heater function on Ebay and hope to have it this week. I have high hopes...

I'm surprised that the heater can talk iBus as these are generic units that can be installed into any vehicle. I would think that any signal it receives from the car must be simple hi-lo voltage signalling.

Have you looked at the MG-Rover sites? They have done a lot of work on these systems. Also I think bimmerworld.co.uk have done a lot of research. Google telestart finds a lot of these references.

Let us know if the heater controller change helps. I still have no idea why mine does absolutely nothing.

That's the catch...these are not generic units. They are specifically designed by Webasto for BMW (or at least the heater CPU is) enabling them to understand and be able to transmit signal on the I-bus.

OK, temperature was down last night to about 2 deg C so I was able to test. I turned on with Direct mode and the fans blew but then immediately slowed and stopped, leaving me to hear the heater running. I tested the exhaust outlet and although not hot, gas was being blown out. After a few minutes, it stopped and all was quiet. The display showed that Direct heating was now off as was the red fan indicator, as if I had clicked it off myself. I clicked it on again, but although the red fan came on - NO heater. I switched everything off and tried again and although the fans didn't move this time, the heater did come on, again just for a few minutes and then it all turned itself off. I was unable to make it start again, even after turning it all off and on again.

So, sounds a bit like yours, but with the added issue of it usually not starting at all. There's something not right here. We've both had out OBC re-programmed to enable heating and it doesn't really work. Others who have had this done have merely reported that the remote would then work, but did it work from the OBC screen?

I'm rather in the dark here. Once the heating has been enabled, should Direct and Timer operation then work faultlessly from the OBC screen? Can anyone confirm this?

When I started the car I think the heater came on for a bit, but it was difficult to tell (too dark and cold) and I'm sure it again went off after a short while. All of which would explain why the car does seem to take a long while to warm up. Maybe I also have an additional fault?

after all that reading what I need to confirm is on my 2004 3.0d I have the extra little exhaust under the passenger side of the car, and the webasto thermotop c in the engine bay, what does this do?

Does it kick in automatically when I turn the car ignition on when the weather is very cold, and heat the engine faster?

YES, WHEN YOU START THE ENGINE.

Wow, this is a tricky problem, I'm wondering if the electric circulation pump fails if the heater is cutting out the heating via a safety thermostat to prevent damage, it could explain why the heater may run for a few minutes until the coolant is up to the required temp' in the heater unit, if accessible maybe you could test for +12v across the pump or check it's continuty. I'd like to enable my "parked heating" function, please let me know if there is a solution without resorting to a "telestart" remote. Best of luck everyone !!!!!

Hi guys.

I've read this thread and I am not completely clear.

It is obvious that the diesel cars do have the auxiallary heater that would warm up the engine block (engine block heater). It is possible to "retrofit" those diesel cars with a remote control that will enable that feature.

What about gasoline engines? I have a '02 4.6iS, and on my navigation screen I have Aux. Ventilation for the venting of the interior of the car, and no heater option, that possibly would have heated the engine.

Is it possible to retrofit an engine block heater into this type of a car?

I am leaving this tropical paradise pretty soon and my next assignment is in Moscow, which is the 4th coldest capital in the world (UlaanBator, Astana, Ottawa holding the lead positions). Looking at the realoem under the 4.6is in EC version, it seems that an engine block heater is a possible option. Is it a DIY project or is it a dealer installed option?

Thanks

Auxilliary heater
 

Have a look at this thread on x5drivers.co.uk

Go to the index page, How To's, Then enabling parking heater..

If someone wants to host the Webasto Aux Heat retrofit document for M62 gasoline engines (4.4i and 4.6is), let me know and I can forward them.

According to the retrofit guides, yes, you need a new IHKA HVAC controller...

Just curious, do you have or know if there is a similar retrofit for the N62 ?

According to ETK it's available for the N62...
