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

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.
