AWD and DSC malfunction, Engine malfunction, DBC malfunction
 

WTF. (UPDATE bellow)

2008 x5 4.8 with 85k on the clock.

Does any one know if my transmission is failing?

On a way to work driving the x5 and then system malfunction pops up, and car is not drivable.
Why would engine malfunction follow AWD and DTC malfunction?

It happened last week and I had a local BMW mechanic take a look at it.
Since all modules needed a Firmware Upgrade all they were able to do is software. After driving this thing for about a 150 miles the problem is back up.
Some of the old codes I saw (provided to me by mechanic):

DSC
5dea dsc: transfer case: temperature
6e83 dcs: tyre pressure control: interface
5d95 dcs: control unit, valve relay
6e7d dcs: sporadic undervoltage detectedby EMF control unit. Delete fault memory
5f77 dsc: Engine management: interface

EMF
601d dcs interface: signal invalid
601e dcs interface: signal invalid
6023 Control unit: faulty power supply
6041 message error from dsc control unit
d359 no message from EGS control unit, receiver EMF, transmitter EGS/HIM

DME\DDE
2d32 differential pressure sensor, intake manifold, plausibillity
2cf8 throttle valve potentiometer
2cf9 throttle valve potentiometer 1
2cfa throttle valve potentiometer 2
2a6b Valvetronic, power limitation
2d13 air mass sensor, rationality

Here are all the warnings (pictures):

UPDATE:

This problem was diagnosed to be a failing throttle body. The best part of troubleshooting this was that the throttle body would pass adaptation and not fail during this.
My final understanding of this problem and the troubleshooting of it is that; this problem can be generated by two devices in your x5. Those two devices are bad ecm and failing throttle body.
In my case it was a throttle body. At this time the SAV is at 114k and the issue has not returned.


Another UPDATE:

Some have troubleshot this to be a wiring issue as well.

How old is your car battery?

Bingo. Same question I was going to ask.

OP- let us know. There are odd issues when the battery begins to fail on these cars...modules get spurious errors as all the handshaking that goes on can be interrupted. You'd think BMW would give you a "bad battery" warning but they dont. You can search here and BF for similar stories. One guy spent thousands with a dealer chasing nonsense, finally a $200 battery did the trick.

+3 - first thought was the battery.

I would agree with you if it was not for the battery been replaced over a month ago.

Today I moved the truck over to get my bike out and I see a thin fluid on the driveway.
I wonder if its out of transmission fluid?

BMW battery, correct type and all....registered? Did you have the issues after the battery was replaced ?

Doubt it is tranny fluid, and a dry tranny would not cause all those errors IMO


Back to the fluid, what IS it? Could be AC condensate drain.

a month old battery? what is the source? if you noticed, most folks here point finger to the battery - based on the community experience with those... even your statement that the batteryis new did not phase us off - check the battery UNDER A LOAD... the line in your error log about the undervoltage is very suspicious... if the battery is good, then next stop is alternator... if the alternator is proven beyond reasonable doubt to be innocent, then you need to check the speed sensor modules, the ABS module, the shaft output sensors... even an ambient temperature sensor... since you are getting some of the engine lights, it might make sense to check the spark plugs, coils, fuel filter and fuel pump... if all checks out fine, then move into the tranny... unless you see the sprockets and the tranny gears laying on the ground as you drive away, i would not tamper with tranny when there are so many other things that can go wrong...

you want to go from simple to more complex - this way you will expend least amount of money with the most amount of results... imagine that you overhaul your tranny (which probably will benefit from proper overhaul) and at the end of the day find out that a $20 speed sensor that you could replace yourself was the culprit all along...

i had the same problem with my 08 4.8i.

turned out to be the throttle body harness.

bmw had to cut and splice a new harness on.

"same"???????

You had those 16 specific error codes?

Not sure about the codes but had those messages come up on the idrive and similar behavior as you described.

when you start up your car right now, it is very rough similar to a misfire right?

DSC, Engine malfunction warnings
 

Got the same x5 4X4, DSC warning a couple times over past two weeks. On one occasion the computer cut power to the engine and the engine malfunction light came on too.

Dealer today said a BMW bulletin exists about this. A faulty cable harness is the problem. A replacement is the solution. He's overnighting the part for immediate install.

Will post update after fix.

2009 BMW x5 4.8i, 55K miles.

interesting...throttle body harness like jlam posted??

Let us know, and please get the SIB number (service bulletin number) when you pick up the car.

DSC, Engine malfunction warnings BMW Bulletin Fix
 

Here is the fix: BMW Bulletin #61-15-09. Repair cable part 12-51-7-602-973.

My 09 x5 4.8i now drives like a completely different vehicle. I dropped off a gravel truck and picked up a 3 series! Throttle tip-in is now smooth, shifts are snappy, acceleration smooth and strong!

Hat is off to Carrera BMW, Bend, OR for doing the research and fixing the problem.

Searched for the bulletin, cannot find it ... Can you please post as a PDF if you have it? Or direct me where I can find it?

Thanks :thumbup:

I do not have the actual Bulletin, just the service incvoice referencing the Bulletin and part replacement. It is as attached below. I would presume any BMW dealer can look this up and discuss with you. Hope this helps.


https://dl.dropboxusercontent.com/u/...094418_494.jpg

I still have no update on the car status.
Stay tuned folks. :/ I am starting to miss my X (that sounds a bit needy).

UPDATE:
Got the car back before the weekend.
So far I've driven about 260 miles and everything is ok.
Following work was performed:
- Engine Malfunction: replaced throttle body
- adjusted steering angle sensor and re-calibrated

So far so good. We will see in few more days.

FINAL UPDATE:
Got about 600 miles plus on the car, since the repair, and everything behaves.

Considering the issue fixed.

Cars in the shop again for engine malfunction..AWD/DSC malfunction. Throttle wire harness/throttle valve replaced last week. I have a brand new battery. Any thoughts on what this might be. Thanks.

If you JUST changed the battery and the message came up, turn the steering wheel to the left until it is at full lock, then back to the right till full lock and back to the middle. Every time you disconnect the battery, you have to do this. Hope it's as simple as a fix :)

Thanks. The battery was replaced 6 months ago. The dealer states it could be wiring harness (cable). They are repairing X5 with the same issue to confirm resolution. My baby will be next in line for the repair.

Malfunction Solved
 

Feel free to skip to the solution down below. Otherwise, here's the full story...

Back in december I experienced identical symptoms on my 2008 X5 4.8i (44k miles): dashboard lit up like a xmas tree and nav screen displayed AWD, DSC, Engine, Brake, etc. malfunctions. At the same time the car would go into limp mode (basically not drivable) and I would have to pull over, kill the engine and restart the engine to continue driving. Some of the lights/malfunctions would stay ON but the car was drivable.

I checked the battery and found that it was reading less than 12V on my meter. I put it on the trusty Battery Tender for approximately 24 hours. Checked the voltage again, it was at 12V exactly. Too low. I did some googling and came across posts that said a low battery could cause the symptoms I'm seeing, so knowing that a new batter has to be registered with the onboard computer I took my car to a local BMW independent to replace the battery. They agreed with my diagnosis and $300+ later (with labor) I'm experiencing the same symptoms.

The same independent used a very expensive Autologic diagnostics device to simply clear the codes and sent me on my way. A few minutes I came back so they can read the newly generated codes (symptoms came back just a few miles after leaving the place). They found some Throttle Body related codes. His initial conclusion was to replace the Throttle Body motor (as he called it).

SOLUTION: My dad and I got together, disconnected the air intake from the throttle body (very easy to do) and found that the throttle plate and the inside of the throttle body was caked with dirt. We concluded that the throttle plate could easily be sticking and causing the onboard computer to freak out throw the car into limp mode. I bought some throttle body cleaner. Dad turned the ignition on and pushed down and released the gas pedal. This opened the throttle plate for a few seconds which allowed me to reach in do a bit of cleaning. Repeated this process several times until the plate and the body was free of dirt, squeaky clean. 1500 miles later the symptoms have not returned (spit three times and knock on wood).

Just thought I'd share since this seems to be a very common problem out there.

Thanks for posting. Two weeks and counting as of today. Car still in the shop. Dealer states BMWNA recommend replacing a wiring harness. Another X5 was in before me and they are getting the fix first. They are testing that vehicle to confirm fix. They will work on mine shortly. Maybe I should suggest this fix? I would hate to tell them how to fix vehicle ;)

Sometimes you have to tell them how to fix. Hard to believe, but there's a lot of guess work there in the shop. They just throw parts at the problem in hope it goes away.

I agree. Throwing parts at the problem is the norm. Maybe they should call the main office more often. However, that would make the service dept look incompetent.

Shop forearm should have an idea today on the repairs.

What year is your x? If it's a 2007, I might know what the problem is. I had mine at the shop for over 10 days chasing ghosts.

Perhaps pay a visit and talk to the shop foreman. You have a complete right to see what's being done to your vehicle. Just nicely ask to take a look, then mention that your "close friend" had exact same symptoms on their vehicle, and perhaps they can check throttle body.

I have 09 4.8. The SA states that have the approval to replace the wiring harness. The throttle body/wire harness has been replaced. Battery is brand new. I guess it could be alternator, but you would think they would have ruled it out. Another X5 was in for the same thing and BMWNA suggested the wiring harness replacement. The other vehicle is ok now. I should have the vehicle back by Tuesday. I keep you all posted.

Which wiring harness?!?!

You posted earlier about a harness replacement.... but others have posted the harness fixed their issue. Will this be a second and different harness they are replacing?

When they call with info, dont feel intimidated - ASK 'what is the part number, what is the SIB'. When the jerkwad SA says "I dont have that in front of me" say "No worries, I'll wait". :cool:

Good point ard. I think he said the main wiring harness. Not sure...:dunno: The throttle wire harness/body was replaced a couple of weeks ago. The SA stated they had the approval from BMWNA to replace. This was an odd statement?? My vehicle is still under factory extended CPO warranty. I'll post Tuesday when I get the vehicle back..I hope.

Finally got the vehicle back today. Here is the fix (at least I'm hoping it is). Engine wiring harness (12-51-7-570-407) replaced. Puma case submitted. They also found a faulty gws. This was also replaced. I'm hoping this does it. If not, I'm going to have to look at the trade in program.

Has anyone used the BMW trade in program because they cannot fix a problem?

I've just updated the post.
In my case it was a throttle body. I heard of two more cases like this: one was a throttle body the other was a wiring.

Good Luck.

Thanks for the update. No more error messages as well. I think we are good on this front. Vehicle going in tomorrow for hesitation at the line. The vehicle will surge into 2nd gear. Usually occurs with heavy load (A/C on). The car seems sluggish in general. I've read several posts on this and I hope it does it when I take it in tomorrow. Maybe adaptive drive reset?

Keep me posted, same thing is happening to my e70 intermittently.

I Just picked up vehicle. SA/shop forearm did a great job going the extra mile. They contacted PUMA regarding ZF transmission and requested assistance. They recommended a reprogram DME idle conversion...sounds good. The cars seems more responsive now. I'll keep you posted..

Great, thanks for the update. :thumbup:

Update: The vehicle is driving great! The shifting characteristics are now more reminiscent when I first picked up vehicle. One thing I noticed was the mpg seemed to lower. I'll test on the highway this week. Not sure if its related to the DME reprog. Any thoughts on the mpg? Thx.

4.8 on highway should be hitting 18miles/gallon, but if you are pushing it and hitting 100miles/hr (I don't know anyone who does that), then I heard the mileage may be about 15.x

Average in the city should be about mid 13miles/gallon. Again, unless you drive in Drive Sport then yo can get those numbers lower.

All in all you should be getting close to 350 - 400miles/tank in on highway going an average 70 miles/hr. 250-300miles/tank driving around town with some moderate highway and traffic.

Thanks! I'll keep an eye on it. I drive fairly conservatively, but we all know why we buy BMW's.

I am having that issue today. who did you take your x to for repair?

just getting the x back today from bmw dealer they changed out throttle body wiriring harness , a $21 part , with labor my bill was $300.

If you are in Atlanta market, go to Solomotorsports. Ask for Boris or PJ, and David most likely will be your tech.

lucky me.... only a bad battery. AAA jump, then new battery at my indy:thumbup:
reset all codes and I'm good to go:D

Just had the same thing happen to my '08 X5 4.8. They told me there is an updated harness for the throttle body.

Sorry to dredge this back up, but the same thing is happening in my 07. They thought it was the intelligent battery cable, but $300 later it did it to me again. Does anyone know if the throttle body bulletin covers the 2007?

http://www.xoutpost.com/792497-post12.html

Just so you know, this is a service bulletin, not a recall. It applies to all E70s up until roughly the time they first published it (one assumes they fixed the mfg process)

(I just googled the SIB number to find this, BTW)

I don't remember the bulletin mentioning anything about 2007 models but it doesn't hurt to try the fix. The part is fairly cheap and it only takes about 30 minutes to do if you want to DIY it. I recommend getting some good quality butt splices to connect the new harness (unless you plan to solder the harness) because the ones BMW provides are complete junk.

Hmm, well I'm taking it back to the shop today and I'll have them do it, since I'm $300 in the hole to them already, so I'll argue that they do a peek-a-boo gratis.

So (I initially posted this), I am back to this same issue again.
Now on another throttle body and maybe spinning my wheels here.

Can you tell me what end of the harness did you have replaced?

I don't know if it helps, but I saw similar stuff on my dashboard when I worked on the oil cooler gasket. Alternator was already removed and battery was running low.

It may be worth a try to retest the battery under load, and if it's good, to re-register the battery after charging it to 100%, followed by clearing out all the codes.

I hear you but in my case I already know if the wire harness, just not what end yet.
Will be working on this later on today.


UPDATE:
I took the truck to my guys at a local shop I sometimes use.
They suggested I look at and if needed replace Throttle Body wire harness.

- I cut the wire harness protective housing in half to see if any of the conductors were rubbed through, all look great
- next I traced all six wires all the way back the the computer (located in engine bay passanger compartment under the cabin filters), all tested good and did not appear to be shorted to each other
- I stripped the dash (glovebox, display center and right vent grills) and looked at all wires in there to make sure nothing was rubbing on the metal frame of the dash (this was suggested in some writ up I sound but I believe has no connection to this issue)

My mechanic deleted all the codes when I dropped the car off and it has worked good since they did that. Obviously this appears to be a problem that develops over time.

Next on to more troubleshooting. (updates coming)

Any update?

Bump as my 2010 X5M is shitting the bed...new drivetrain fluids a year ago, 90ah AGM & registered within a month, voltages read from mid 13's to a high of 15.1 but averages 14.5, wheel speed sensors cleaned this week.

I’ve read the steering angle clock in the steering column could also be bad or the actual actuator on the transfer case. I’m in the exact same boat and spot as you...

AWD and DSC malfunction, Engine malfunction, DBC malfunction
 

Also, another UPDATE:
Pulled glovebox to check wiring and found that my wires had been wrapped in felt tape(this was a TSB regarding the extremely sharp edges of the metal in the dash rubbing and cutting threw wires and causing crazy and random codes, including 5DEA), so I removed the felt tape to inspect the wiring. I did find what appeared to be 2 wires that seemed to have been shorted to ground at one point. I traced these wires and they went to a suspension control box on the far right(passenger side dash-accessible by removing plastic between dash and door panel). So, I don’t believe in my case these shorted wires effected my issues. But I did also find my blower motor had a wire that was barely holding on and a wire in the suspension wire harness that wasn’t totally connected in the connector... I have preformed this repair, retapped the wires with just electrical tape, but covered the wire and metal with automotive black carpet to protect at all areas of concern and glued them in place. I haven’t driven the truck enough yet to see if this fixes my 5DEA code or not, I’ll update when I know more... https://uploads.tapatalk-cdn.com/201...57f1139053.jpg https://uploads.tapatalk-cdn.com/201...6a6a04f57a.jpg Wire traced to module https://uploads.tapatalk-cdn.com/201...4a3688fa0d.jpg Rubbed through felt https://uploads.tapatalk-cdn.com/201...f1a28e42c7.jpg Not clicked in all the way https://uploads.tapatalk-cdn.com/201...9296a7d2cd.jpg Small wire on blower motor harness one or two strands holding the wire on.

shorted/grounded wires at various locations CAN have an impact on modules far away if they interact with the bus communications in some way.

just fyi

Great. Please explain in greater detail please...

This fix your issues, BoostedX5M. I'm gonna pull my glove box for shits and giggles seeing as the throttle body harness sounds 4.8i specific but this wiring issue is likely E70 generic and I'm not gonna wait until BMW figures out common errors across multiple platforms can happen, ie N54 and S63 injectors are the same, fuel pumps, etc etc but since there's fewer X's (and even fewer X5M's) on the road vs 3's that we get the tail end of these SIB's.

Here is one TSB. It’s not the original TSB, as the original has the throttle body wiring you mentioned.

Here’s another one I found.. https://bmw-worldzz.blogspot.com/201...nical_210.html

I'm not seeing a PDF but between your pics and link, I'm just gonna pull it when I get home. On a side note, how'd you find this...I've Googled so much god damn stuff lately and haven't seen this site. I wish we had access to BMW's "info only" data collection since I'm sure they get a ton of stuff before they decide what fuckups they're gonna own up to.

AWD and DSC malfunction, Engine malfunction, DBC malfunction
 

I can’t find that PDF either, and I searched for days...

Ha. I think the Service Bulletins are on www.newtis.info but they are impossible to find. I don’t know if its fixed anything because I haven’t been driving it lately enough to trip that dumb 5DEA code. I think after reading a few more things... I’m strongly considering replacing the actuator on the transfer case. Have you tried simply unplugging the plug to the transfer case actuator? To see if anything changes! (Note: If you do you will get a abs light and lose abs-from what I have read, but it won’t hurt anything, it just can’t engage xdrive) That’s how many trouble shoot the transfer case. That have issues like yours. Look in X3 and X5 forums. X3s seem to have major issues like we’re having with transfer cases. From what I’ve read. It’s the following typically:
Speed sensor(or wiring)
Plastic gears in actuator
Actuator
Actuator resistor(Which needs to be coded if replaced-but this seems very rare)
The steering chock(in steering column)-Which also needs adaptations

Best way to test is if there’s a way to read values while driving. Like software people use with a laptop to read...
I.e. Speed sensors, actuate the actuator, etc...

Oh, I also plan to test the power and ground wires at the VTG(Transfer Case module) and actuator to make sure there isn’t any voltage drop, as I’ve read both are super sensitive to voltage drops... Might just clean up the connections and hound to be safe too...

I had the same exact issue and it ended up being a missing Transfer Case module(By the Battery) and The previous owner had the windshield replaced, so for some reason, the ECU had been replaced but never reprogrammed to the truck.

Now I have a loud fan, but i beleive the issue is with my thermostat.

The transfer-case module was was missing or was never programmed? I’m not sure I understand.

Ohh, the front windshield was replaced and the ecu got wet(?) and the transfer case wasn’t programmed in properly(?), so it was missing in the ecu programming(?)

Yet, very confusing....






On the fan running... thermostat? or water pump?



Do your research.... 99 times out of 100 it will be the pump.



Actually, maybe 100
