Hello, just paid the deposit on a Z4.

To keep the information trail live for future reference, it seems all three airbag modules have the incorrect chassis number. It is fairly unlikely all three have been changed, so my next suggestion is that it may be a replacement Light Control Module that hasn’t been properly coded. The airbag modules can pick up the VIN from that and the Instrument Cluster. If there’s a discrepancy it will then put the airbag light on.
@bigwinn , you are closer to Coventry than I am so maybe can help? Or I think the OP is visiting @Number5 to sort the roof motor, so perhaps @colb could pop over for a look?

Thanks for all the support, I am also buying a K+DCAN cable to connect to a computer, is it hard to code at home?
And yes, I have the dot illuminated

Is the tamper dot illuminated? That'll confirm the swap of dash or light switch without VIN coding

Not an e85, but it'll look something like this, by the odometer

I may also need help with another issue, I think I need to set the zero on the brake pressure sensors.
I have a constant offset of around 6.5bar on the full range, but both circuits are linear

Re the pressure sensors use inpa to recalibrate the DTC unit- there are 5-6 calibration actions in the menu do them all
 
Well that sounds like a simpler answer. Hopefully no actual airbag problems, though you’ll need to get the cluster out to remove the blank over the light.
I use Scanner 1.4 to set the correct VIN and odometer reading. This does not update the other info in the module though. Speak to @colb , @bigwinn or @Street to see if INPA etc can do a more thorough job.

Oh and almost forgot: the odometer needs to be updated in Km, even though it shows in miles. Copy the figure from the instrument cluster info.
 
The cable should arrive over the weekend. I will try to do it then. I will probably also need a new battery, which should solve most of the gremlins.

Also, I might need to replace the valve cover gasket as I can see a little oil escaping from it. After a slightly longer and more enthusiastic drive, the yellow oil warning light comes on for a few seconds when I turn off the ignition. However, the oil level looks good.
 
Are there anyone who can offer advice and thrustable links for installing INPA (or any other similar software)?
 
A few updates:

Connected with INPA and when I tried to reset the pressure sensors, I got an error: ERROR_ECU_CONDITIONS_NOT_CORRECT_OR_REQUEST_SEQUENCE_ERROR

Then I aborted after that

I read the VIN number of the LCM and it doesn't match. I will definitely need to code it. Still studying for doing it
 
Updating you all, as some might face the same issue.
Today I took the car back to Kidderminster where I finally met with Number5 to fix the roof. He did an amazing job, and the roof works perfectly now.
The motor was flooded and rusty, which was probably causing a short circuit and generating that long list of errors. After he finished, there were no more ABS or DSC lights on the dash. I measured the brake pressures, and both circuits are reading the same.

Looks like those gremlins are officially sorted. Thanks again to Number5!
