When this occurs the metal contact loses connection with the bulb socket. Production Solution New tail lamp implemented into production for MY21. Service If one or both of the DTCs listed above is stored, it is possible the circuit board contacts have come loose from the housing. Note: Before replacing any parts (bulb, socket, housing or wiring) please inspect the reverse lamp contacts first. Page 1 of 4 © 2021 Audi of America, Inc. All rights reserved.

Tip: Compare the contacts to the adjacent bulb socket contacts in the lamp housing. Then inspect the upper and lower contact on the lamp housing and using a 90 degree pick will help check if the contact is loose or not. Page 2 of 4 © 2021 Audi of America, Inc. All rights reserved.
