Technical Background
Fault in the wiper motor control unit is caused by installation of an unapproved aftermarket xenon headlamp system. These systems are not designed
for Audi vehicles.
These systems have been proven to cause damage to various electrical systems in our models by causing a voltage spike in networks that use a LIN
architecture, such as a LIN-based windshield wiper system.
Production Solution
Not applicable.
Service
Typically this condition is observed when, after replacing a windshield wiper motor, the replacement motor fails again after a short time.
1. Inspect the vehicle for the presence of any aftermarket accessories, most notably a non-approved xenon headlamp system.
2. Inform the customer that the windshield wiper motor has failed as a result of the installation of aftermarket xenon headlamps and is not covered
under warranty.
3. Restore the original headlamp system.
Warranty
The damage is due to outside influence and is not covered by any Audi warranty.
