Update Transmission Firmware
 

First time posting here. Nice to meet everyone. I'm an American living and working in Kuwait. I own two 2005 X5s, one 3.0i and one 4.4i, both of which I've made various upgrades and repairs to. I'm at a sticking point on upgrading my transmission.

The short version is I'm trying to use WinKFP to update the transmission. I have SP-Daten V65, but my transmission has apparently never been upgraded before since its creation in 2004. After asking WinKFP to update, I get an error 701 for determining compatible hardware types stating I need a new Sg D2 file. If you can help me with how to host pictures, I'll be happy to provide those. Any ideas? Thank you for any assistance.

DDE is in diesels car only (Digital Diesel Electronics) - are you selecting a DDE module on your petrol cars?

That was my thought as well.
But I don't see the EGS in the list.

Is there a sub menu for GKE194? Is that not for N62 6 speeds? I def need to get my software updated as well.

7541027A.0PA is found in GKE194 folder.

My car is certainly not a diesel. Does the diesel and 4.4i use the same transmission? When searching the part number, I do come up with about as many results for 3.0d as I do 4.4i. I'll see what I can find in realoem later.

Other than toying a bit with INPA to reset faults and using it to fix a VTG issue, I haven't successfully used any of the other software I have. This is my first foray into "coding" or updating any modules. Thanks for any assistance.

what's the point of updating the firmware here

If you've had some parts swapped out and coded (I'm using the term loosely) you can have the scanner pick up the other part when scanning in automatic (don't ask how I know..)[emoji850] and that's why the DDE shows up [emoji28]

I suspect I may have a bit of a Frankenbeemer. What module should be the transmission? GKE194?

As far as symptoms, I've got a nasty 2 to 1 transition and some slippage at what seems like 3rd gear. I thought it was due to the seal for the mechtronic and replaced it, then cleared adaptations, but the issue is still there. Going through the gears manually, it holds all of them strongly. I'd like to upgrade the firmware to clear any suspicions in that regard, then consider a rebuilt mechtronic as an option.

I will be rebuilding anyway as there is no way around it....but updating firmware seems appropriate as well.

That number is the part number (7541027) and it is found in the files somewhere? That's some sound info. Thank you. Why when I search for the assembly number, 7541100, is it not found then?

7541100 ? 7541102 was the latest assembly nr. for that hardware in 2010.

Here you can see how the software/assembly numbers have been updated. You can follow the string if you like.

Where do you get the 7541102 from? I saw 7541100 in the list...where do I find this list? Is it in the software (NCS) files?

Check again my previous post.

All this info is in the Daten files.

x.xx.x_daten/ecudata/E53/data/GKE194

Check .DAT and .HIS files and open them with notepad.

Ok, so this is saying for part number 7541027, I should use assembly number 7541102? I'll check this afternoon. Hopefully an update with remedy at least a small portion of the issue. Thank you very much!

Confirm EGS ZB Num
 

Hey Clavurion,

I'm going through the same thing, just to confirm, when you say 'follow the string, I interpret that as you find your original ZB number and follow it as it gets translated from 'ALT' to 'NEU' ?

My original Assembly Number from INPA is 7549950, so I found that in this HIS file as:

7549950,7559106,00,2P
then
7559106,7558470,00,2P
then
7558470,7564915,00,2P

Then across in the DAT file I found:
7564915,1000000,7557063,A,7564916DA,0FFFFFFFFFD,01 6,1 8

I also recognise the appropriate 7544720A.0PA file corresponding with my HW number.

Therefore, in WinKFP, I enter 7564915 which finds the EGS as GKE194, then I learned to change diagnosis protocol to KWP2000* and am prompted to flash.

Is that all correct? I understand with a healthy battery it should only take about 5 minutes to update compared with the DME, no charger needed.

I am trying to correct shunting issues in 5th gear (mentioned in other threads) and the 2-1 bump. I have no error codes in EGS, I have replaced the ZF sleeves, filter, fluid etc. Have followed the adaption procedure as well.

Many thanks for any advice. Dave in Western Australia.

Hi Dave
Did you ever go ahead with this software update? I have a 3.0d with the 2-1 bump and would be keen to hear if the software update resolved the issue.
Cheers
Nial

Hey Nial, this feels like forever ago, but yes I took a leap of faith, and it did fix the 2-1 bump problem but not the 5th gear shunt. The shifting had a marked improvement.

The car is at the euro specialist to for some issues with cam advancing on one bank and they have fixed that now, I thought it was an ignition problem. I'm hoping that it helps with the 5th gear problem, as minor and infrequent that it has become over time.

Dave

Hi Dave

Thanks for responding. Yep it is an old thread, I've been trawling through lots of them trying to find the solution to my 2-1 bump. I've always suspected it could probably be a software issues as its completely gone when if i switch to sport mode on the transmission. I recently installed some BMW software (INPA, WinKFP) to troubleshoot my rain light sensor as the rain sensor stopped working. I'm learning my way around INPA and was trying to find out what version of software my transmission has and how I might update it. That's what lead me to this thread.
Any chance you can help me out with finding out my software number for my transmission? I can't seem to locate the assembly number, i can only find the BMW part number. I'll post the pics from INPA.
Cheers
Nial

What you are looking for will be called an "Integration level" or i-level for the transmission (EGS). Not sure how to find it in INPA, I always use ISTA-d or ISTA-p for module integration changes. I updated mine at some point in the past but don't remember the latest number. Could scan the truck for you if you need it to compare to yours once you find it.

As for your 2-1 bump it's unlikely to be a programming "issue." Likely your seals and/or solenoids are loosened up and the fluid isn't holding pressure anymore. Cured 2 E53 ZF 6HPs with a full transmission service (tube/bridge seal, mechatronic sleeve, pan/filter, and new fluid). 1 of them had a reverse to drive delay in shifting along with a slight 2-1 hard shift. The other had a HARD 2-1 slam. Felt like being rear ended badly.

I still can't locate the assembly number in INPA. I haven't got ISTA so not sure how else i could find my correct assembly number.
I did find my BMW part number (7544720) in the DAT file and used that to locate a ZUSB number (7549968).

Using that ZUSB number 7449968 I connected to WinKFP to see if it would show me what update is available. I entered the VIN and changed to KWP2000* and this is what it should me as available. I didn't proceed with it as I want to make sure I have the correct one before doing it. I'll post the update it showed was available.

The 2-1 bump/slam does feel like someone rear ending you. Its very predicable in my car once it was warmed it. Not sure why it doesn't happen in Sport mode, maybe it doesn't change back down to 1? I had the fluid changed about 5years/50 000km ago. Hopefully he changed the other parts back then but i don't know for sure.

You need to service the trans for the 2-1 bump, fluids, seals.

it 'doesn't' do it in sport mode because it shifts to 1 before coming to a stop, unlike in drive, where it shifts to 1 at almost stop.

It is not a software issue.

:iagree:

check transmission adaptation values. anything over 200 is an indication of worn out bores in the valve body and pressure regulator defects. Requires removal of the valve body to check with a vacuum measurement. Oversized spool valves are available for ZF6 trans

Thanks for the responses. Looks like I need to find somewhere in Brisbane, Australia that can do a fluid change and replace the seals for me as that's beyond my ability.

Not that hard todo i done my 2005 4.4i then done the firmware update then done the relean mine been smooth as . Take 2 hrs cost like Est for parts i used only ZF and ZF6 Fuild .The Filling Process was little pain i found . may help ZF email the file attached https://www.dropbox.com/sh/22jw813n2...Z4OXyyzpa?dl=0

Are these the values you were referring to?

https://www.youtube.com/watch?v=20Wz03GFa5k may help to expain there 2 videos :)

I thought I'd come back and update this post as I ended up having the transmission serviced.
I found an independant transmission shop to do the work and he had done lots of fords that use the same zf 6 speed transmission. Cost was $688AU to change the fluid, pan and filter, 4 round tubes seals, square/rectangular seal and the plug seal. The fluid was very dirty and the seals were going hard and pressed flat so they needed to be done.

It does drive much better and the 2-1 bump is gone when cold. Once warmed up it still does have the 2-1 bump but it is a lot less pronounced. It pretty bad before the service and it is noticlably better now but it will still be present if i roll very slowly to a stop.

Couple of options I have now are
1. Do the software update myself (although I'm not keen on this option as i don't have the voltage stabilizer and don't want to risk bricking it)
2. The transmission shop suggested calling BMW and see what they will charge to update the software modules, he said it should take more than an hour so probably be around $220AU.
3. xHP Flashtool - I've been reading up on this and it could be an option. This looks like it remaps the transmission with some improvements. I don't know if this would cure the 2-1 bump though...

I ask about resetting the adaptations, he didn't recommend doing it. He said it will adapt was i drive it around. Any thoughts on this and is it worth doing?

I’m using XHP on my E70 6hp28.
Tried stage 2 & 3. It flashes fast .
On my e53 6hp26 I used to have the bump and just serviced it myself and it went away . I agree about not resetting adaptions . Everyone does it , so it’s easy to do with ISTA if you want;
but it adapts to wear of the clutches etc. so my thinking is you want the transmission to be adapted to current level of wear.

What fluid did the transmission shop use?

The fluid and pan/filter were geniune ZF. The rubber seals and plug adapter were aftermarket. He said he has been using the aftermarket seals and adapters for a long time without issue.

When you serviced the e53 6hp26 did the 2-1 bump issue go away straight away or did it take some time? I was wondering if the transmission will take a bit of driving to adapter to the new fluid and seals?

With XHP does it just download the software straight from your phone to the car? I have plugged it in and got it to read the my transmission and that all worked fine. It made a backup of my transmission then was able to see some wear values.

I actually serviced it twice to try and get a greater percentage of new fluid in there. I didn’t use genuine Lifeguard fluid as I’ve got a XR6 turbo with a ZF 6hp26 and used other fluids in that so knew it’d fine, I think the bump was gone pretty much immediately.
With XHP I wasn’t able to use my phone;
I used the same cable I use with NCS/ ISTA/ etc and a windows laptop.
I don’t know if XHP will fix your bump. I think you can see current adaptions in XHP but not reset them , as XHP doesn’t recommend it.
I flashed it without even a battery charger connected.

https://xoutpost.com/attachments/x5-...c-software.pdf
I done that update just turn off all acc like stero ecta and updae took like 20 mins using NCSEXPER and D can cable for my E53 N62 with 6HP i done the seals ecta and used all ZF parts and fuilds with mine with the relearn is not simple as reset and fix it self there is produre that follow afte it like takes 1 hr for it .

That sound like the fix I need but i note it only references 4.4 and 4.8 models. Mine is a 3.0 diesel engine, model year is 2005.
I thought updates for transmission modules were done through winKFP?

I followed this you need liek chrome to change it english https://m.blog.naver.com/livinda/220790197476
All can say is check the GS19 Version on yours and see if maches the version update .

did they install the Sonnax Zip Kit?

No they didn't any kits. Just changed the seals, plug adapter and fluid.

How do you find xhp? It looks like a good product and the option to have the gear display on the cluster looks pretty neat. I thought i might be able to use it to sort the 2-1 bump as i see it enables you to change shift parameters. Mine only has the bump in D mode. In S mode the bump isn't there so my thinking is the car shifts down to 1 while you are travelling faster and it isn't noticable in S mode. By the time it stops in S mode it has always changed to 1 so there is no bump. In D mode I can slow gently to a stop and will always get the bump. If i stop quickly the bump still happens, it just occurs with the car stationary and you have your foot on the brake. The only time i might not get a bump in D mode is when the car is cold, once it warms up it will be there.

I have XHP on my e70. One of reasons i got it is try and mask the bushing wear on the e-clutch, as you can make it hold gears longer or down shift later etc .
I have no problems with my e53 transmission so I never bothered with getting it for the e53.
I found some pics of XHP on a e53 with the gear display enabled- top is Drive;
centre is in Neutral,
bottom is in Sports mode.

I'd have tried cheaper fluid before the ZF. Especially since they did not rebuild the valve body. Did they reset trans adaptations?

But to answer your second question. After servicing my 6hp26 with aftermarket seals, Valvoline Multi-Vehicle Synthetic ATF, and resetting trans adaptations, the 2-1 slam was gone immediately. And it was a severe slam, like getting hit from behind @ 10mph.

No haven't reset the tran adaptations. The advice from the transmission shop wasn't to do it. I do have INPA so have the ability to do it, main reason I haven't yet is I saw there is a lengthy re learn procedure so I would need to find the time and a suitable place to do that.

I contacted xhp flashtool to see what their product can offer. They said their software is built on the latest bmw software so if a bmw software update was to cure my issue then xhp should also do the same. The price was around $320Au for the license and 3 maps. I would probably only use the stage 1 map if I got it. I've been trying to find a good review of xhp with a diesel to see what it's like.

:popcorn:

I updated the transmission with ista-P on my e70 before I flashed it with XHP.

Maybe that wasn’t necessary if XHP are suggesting it updates it anyway.

I tried stage 1 for five minutes of driving and seemed no different to stock,
so I then flashed stage 2 and to me it was still pretty mild .
I’m on stage 3 now and in sports mode it shifts much faster but not harsh .
In normal mode even with stage 3 I don’t think anyone would really notice.

In sports mode with stage 3 as you slow it rev matches, which I think is dumb for a diesel.
There’s no way to disable that except by either just using stage 1 or 2 or just drive in normal mode .
There’s other options available to customize any of the stages -
lock out or enable 6th gear in sports mode;
Valet mode, drag race mode, and change when it upshifts and downshifts through the gears, rpm limit ,
and a few other options.

Thanks for insight into xhp. Do you happen to know if ista P can update the e53 transmission? I got ista D working all fine but haven't tried ista P. I researched doing the update via winkfp but was 100% sure on how to do it. Ista P I'm assuming is an easier process as it should identify the modules and their correct software rather than having to select it like in winkpf?

I don’t think you can update e53 transmission with ista-P.
Although ista-P is simple to navigate, it’s very limited in options. No choice which version you update to, and various modules all tied together. Also I used an ICOM to connect it to my e70 . Also must have big amp power supply.

WinKPF is what you need for e53, but I haven’t used it to update my e53.
Maybe because my e53 is an august 2006 build , it already had a later update version.

I took the leap of faith this morning and ran the software update for my transmission. After researching how to use WinFKP a bit more and understanding how it selects the software numbers after I select my gearbox I gave it a try and it worked. I charged up my battery overnight with the small ctek charger and left it connected. My battery is only a couple of months old and from my research the update takes 20-25 mins so I crossed my fingers and it held out. It is a tense 25 mins while its happening.
Did it solved the 2-1 harsh downshift? Almost, it does drive very nice now and i'm glad it is running to latest software for that model gearbox. It does seem to shift from 2-1 a little before it comes to a stop which makes it less pronounced. If I roll really slowly to a stop I can reproduce the 2-1 bump so hasn't cured it 100% but its less present. Having the fluid and seals changed has definitely made it much better to drive. It must have low on oil because it always used to have a strange shift from 1-2 when turning when cold, almost like it would fall out of gear for a second. This would only happen when cold and went away once it was up to temp. Since having the fluid and seals changed this has not happened again.

you need to do the relearn adavite reset follow the steps https://blog.fcpeuro.com/how-to-rese...daptations-zf6 look at Relearning Adaptations Table GS19 and Follow the steps after the reset take like 1 hr ish . then should relearn. where they got E90 change it for the E53 and be same steps less the relarn table

Thanks for the information. I would like to try this, just need to find a suitable location to do it.
Have you tried it and if so what were the results like? I keep reading conflicting views on resetting them so it's hard to know what the go is.

I'm not convinced the adaption process is an absolute requirement. Sure it is, if you want the trans to behave perfectly an hour after you reset it but in most cases it will re-adapt over the following days/weeks of normal use.

Mine did. Twice. And it was days, not weeks...

Good point. I figured it must have a way of working itself out if it's reset and the procedure isn't followed.

https://www.youtube.com/watch?v=20Wz...gnosticNetwork there 2 parts but part 1 expain why needs to be done

Again, this is from the view of a shop owner, needing to present a well-sorted transmission to a paying customer. I totally get that, as well as the DIY owner that wants to sort the trans adaptations as quickly as possible.

But they will sort themselves over time anyway, and will continue to do so, even after the above procedure. ;)

The good take-away in the above video is monitoring the adaptation values over time - although I'm guessing this is more than most owners (or shops) will likely ever do. :rolleyes:
