TECHNICAL BACKGROUND
This condition is caused by a function check of the Electronic Damping Control Module that coincides with the engine start.
After the Electronic Damping Control Module recognizes the signal ignition on," the shock absorber initialization is started. The motors of the
regulator valves are checked in turn by brief current supply.
Because of the high voltage required for the engine start, the function check is disrupted, and as a result, the above DTC entries are generated and
the Adaptive Dampers warning light is illuminated, with a message displayed in the Driver information display Suspension: System Fault.
The warning light goes out after an ignition cycle.
This condition does not affect the handling of the vehicle.
PRODUCTION SOLUTION
1. Delete the DTCs.
2. Follow all instructions in the attached TSB 2011732 00 Software Version Management (SVM), operating instructions.
3. Update the electronic damping control module (J250) using the SVM action code as listed in the table below if necessary.

4. If the vehicle is an A4 or A5, recalibrate Audi Lane Assist (PR code 7Y1).
Tip: Replacing the electronic damping control module (J250) or the affected shock absorber(s) does not address the condition. Any parts replaced
under warranty may be subject to review and possible debit of the claim(s).
