Coding a secondhand Airbag ECU, can anyone help please?
I think the guy that did mine used Tool32. I'm sure he didn't search for the part number... the module was selected from menus or a dropdown. I know the module number of mine, because I used to search for it daily on various sites. 6935920.
How about searching for the module? "Control Unit Airbag" or "Safety Information Module" those are what Real OEM refer to them as...

Many thanks KIS, I think I'm getting close, in Tool32 I opened STVR85.prg and double clicked on c_fg_lesen to read the information on the module, on the results window I can see the invalid VIN listed next to FG_NR. I confirmed this by opening STVL85.prg and seeing my VIN in that location. Hopefully all I need to do is write out the correct VIN to the module, restart the system time and clear the errors. I'm approaching this slowly so as not to mess anything up, will let you know the outcome, I'm very optimistic!

So that didn't work, trying to write my VIN to the STVR module is resulting in the error message:
error_ecu_conditions_not_correct_or_request_sequence_error
Back for more research.....

waynoh - I searched through my /data directory and could not find your part number in any of my .HIS files. Before I got mine working, I did scour the web looking for older software versions to gather older daten and other files. Maybe give that a try...

Tomjones20194 - Thanks I'e been scouring for days to no avail, still looking for older files, not even sure how old I would need.

Have you tried disconnecting and re-connecting the module? If there was any sort of water damage or rust build up then maybe the contacts aren't clean?

Tools 32 communicates with the module, it returns information with the original VIN, INPA can also clear the error from the module. Tool32 is unable to write the correct VIN to the module and WinKFP doesn't have the correct part number ion the daten file. Is there anywhere to buy the correct daten file for the car?

I'm beginning to think it could be a configuration problem or an issue with the cable, I tried updating with WinKFP and received the following errors. Does anyone have any thoughts?

Reinstall the program (or maybe all 3 programs) and take it from there?

Sorry just saw this reply INPA seems to work correctly, it clears errors as it should. Just received a new cable from BimmerGeeks but haven't had a chance to try it out yet.
Thanks

Received a new cable, same results, yes INPA works correctly, I was able to clear the airbag light with inpa but it returns because the VIN isn't updated in the replacement module.

Something is wrong with the ECU entry I have in WinKFP, if I select the SBSR85 ECU family it gives me 6948086 or 6948088. When I look these numbers up on REALOEM they come back as B-pilar modules and not door modules. Does anyone know why this is happening?

Can’t help answer your question, but perhaps the ECU fault isn’t the airbag module (using your original one)? But another components within the airbag system?
Or the second hand module you bought is busted? Just some food for thought?

Reinstalled the original module back in the right door and read codes again, just returns STVR module fault. I have searched high and low and I am unable to find any E85 daten files that contain any part numbers that refer to an airbag module in the doors. Found this below in another post and was wondering if there are different daten files for US vs Euro spec cars. Does anyone know the answer to this question?
I have been doing some digging on this today and think I can now actually answer my own question, at least partially.
According to RealOEM the STVL/R are sensors in the doors (not to be confused with the actual airbag modules in them). However they are not fitted to Euro models just US ones. There are other key differences in the airbag setup on US cars such as two stage airbags and knee airbags.
