Hi,

I have a Audi A4 cabriolet and have the following fault codes:

01794 - Control module - Incorrect Chassis (VIN) number (intermittent)
00474 - Control module for immobiliser - No signal/communication - intermittent

The vehicle has not presented any starting issues but the airbag light will go out when started and reappear after driving for a little while.

I have checked the Vin numbers in various module and found the following:

Vehicles Vin: WAUZZZ8H63K026006

Engine ECU: WAUZZZ8H17K020295
Instrument Cluster: WAUZZZ8H17K020295
Airbag Module: WAUZZZ8H55K021835
Central electric: WAUZZZ8H55K021835

In terms of changing the VIN number in the airbag module, how can this be done and what needs to be done to solve this issue?

If you can provided further assistants and advice.

Thanks,

Marco

We know you have an A4 and can guess it's an 8H but we need more detail, so we'll need to see a full unedited VCDS Auto-Scan to be able to suggest how you correct the VIN numbers.

BTW - two questions for the experts:
1) what about the VIN number in the Central Electric, does that need to match also?
2) none of the modules have a VIN that matches the vehicle?
