01794 - Control Module: Incorrect Chassis (VIN) Number
Possible Causes
- Control Module was never adapted to a Car (New Control Module)
- Control Module was originally adapted to a different Car (Used Control Module)
Possible Solutions
- Check Vehicle Identification Number (VIN) of Control Module and Car
- Perform Vehicle Data Learning
Special Notes
- When found in Audi A4/S4/RS4 (8K): Audi A4 (8K) Brake Electronics, perform Security Access then Coding. Recode the Control Module using the already stored Coding Value. This will trigger a new Learning Process and the Control Module should update the stored Vehicle Identification Number (VIN).
- When found in Audi A4/S4/RS4/Cabriolet (8E/8H): Heating/Air Conditioning, perform Vehicle Data Learning (Adaptation).
- When found in Audi A4/S4/RS4/Cabriolet (8E/8H): Airbag 8.4, perform Vehicle Data Learning (Adaptation).
- When found in Audi A4/S4/RS4/Cabriolet (8E/8H): Airbag 9.41, perform Vehicle Data Learning (Adaptation).
- When the Vehicle Identification Number (VIN) in Airbag and Instrument Cluster matches, try clearing the fault code. If it does not clear, ignore it as long the airbag warning light is not active. For further details see TPI 2007313.
- When found in Audi A4/S4/RS4/Cabriolet (8E/8H): Steering Wheel, perform Vehicle Data Learning (Adaptation).
- When found in Audi A4/S4/RS4/Cabriolet (8E/8H): Seat Adjustment, perform Vehicle Data Learning (Adaptation).
- When found in Audi A4/S4/RS4/Cabriolet (8E/8H) (if the above Procedures do not succeed):
- When the Vehicle Identification Number (VIN) in Instrument Cluster does NOT match the real one, the VIN stored in the Instrument Clusters might be lost or corrupted. This problem can usually only be resolved by installing a new Instrument Cluster or finding somebody who is able to repair the old one. Additional details describing this problem can be found in TPI 2004680. UPDATE: The current Audi VAS Brand CDs include a new Script/Procedure to write the VIN into the damaged Instrument Cluster again, this is not a permanent fix but similar to what external Companies have been offering for quite some time now.
- When found in Audi TT (8J) [14]-Suspension Electronics, and the J250-Electronic Damping Control Module was replaced, it will be necessary to code the J250 and Re-adapt default ride height positions.
