2022-2024 Audi Models Suspension Control Module Warning

Symptoms

Owners of affected Audi vehicles may observe "The warning light for the suspension comes on in the instrument cluster." This Audi suspension control module warning indicates a problem with the vehicle's suspension system. The underlying technical issue is that the software version management (SVM) registers an unknown event when a technician performs a "Check control unit configuration," which prevents the suspension control module, J775 (address word 0074), from being automatically parametrized.

Diagnosis and Trigger Conditions

During this process, the software version management (SVM) system encounters an unknown event, which prevents the suspension control module, J775 (address word 0074), from being automatically configured or parametrized. This condition triggers the warning light on the instrument cluster.
