Definitely going to follow this, I have a good working version of Tool32, but I haven't been able to program with it just start the system time.

As I haven't figured my mismatch coding out just yet, I was playing around with BMW Scanner 1.4 and I saw a function to change the VIN in there.

Have you tried this?

Ps... If this works out can you send me the download of all your programming data from the SIM? Looking for the hex and programming setup.

I also found that in BMW Scanner 1.4 but it didn't work when I tried to change the Vin using it.
Still got to try with Tool32 when he can get the car to me.

Had another go at sorting Youdy's airbag light, since we replaced the main central module with a same part number one we have got rid of the original fault but have been stumped by the replacement having the wrong Vin number coded into it and is keeping the airbag light on.
Our previouse attemmpts at coding the module using NCS Expert, WinKPF have all resulted in failure despite following the instructions others have used with good results. Our latest session was using Tool32 and again following instructions we found attempted to code the new Vin into the module, it will not take the new Vin at all derspite using the SIM85 program and using the correct arguments the job requires. I did have another go using BMW Scanner1.4 to progrqamme the module but again it will not take the new Vin. I did use the Reset Module button and this actually made the airbag light go off. The next time ignition is cycled it obviously runs through the airbag system check and spots the incorrect Vin again and lights the airbag light again, no surprise there then.
At a bit of a loss now what else to try, I suspect one of the expensive scan/coding tools by Autel or Snapon might werll be a way forward since we have tried all the BMW stuff we have access to. Anyone out there with such kit or suggestions on a way forward.

Wild stab in the dark time....... if everyone else is telling you they managed it, is it perhaps a duff module?

We were told the replacement came out of a working car with no airbag faults, I have no reason to doubt this, supplier is very reliable.
The fact that the only error showing up now is the incorrect Vin leads me to think the rest of the module is functional as are the two satellite modules as they dont set any codes (so far).

Had same issues as you today I think on

acestumacher

car

New satellite b pillar module fitted

Followed the path exactly as described in Toms how to

Still shows as vin mismatch

Did you fix it?

for interest

No didn’t solve it even using my new Launch Tablet couldn’t get it to take the cars Vin I suspect the supplied replacement was locked up from a crashed car. Jon who’s car it was actually took the car to the module supplier in Birmingham and they had a go at coding it and his original without success. Ongoing saga.

Hi, was this issue sorted? can you physically see the wrong vin number? or are you just seeing the fault code? is it possible that you have another module (non airbag) that has a different vin number that this module is complaining about?
