It may seem too simple, but the method often used to reset and restart the control unit of cars in general, not just the Audi A3 8p, consists of disconnecting the negative pole of the 12-volt battery that powers the car, installed in the engine compartment, and reconnecting it after a couple of minutes.

This will serve to delete all stored sequences and start from scratch, provided it is a momentary and sporadic fault, otherwise the advice is always to contact a technical assistance center and submit the vehicle to thorough checks.
