Technical Service Bulletin
3. Remove the covers from the back of the headlamp housing.
Check all of the connectors inside of the headlamp housing
(Figure 1) for proper seating and inspect the locks to ensure
that they are fully engaged:
• Connector “A” can be seated, but not fully engaged
(Figure 2). It is important to hold the projector housing
when this connector is pushed, otherwise, the projector
will swivel.
• Connector “B” can be fully locked into place, but be
rotated 5-10 degrees off-center (Figure 3). Ensure that
the harness connector is seated parallel to the connector
housing on the headlamp.
• Connector “C” (Figure 4) is located behind the motor
mechanism, which rests below the projector lens. It is a
very small two-pin connector that should be adjusted
cautiously. If it becomes fully disconnected, it is very
difficult to re-connect without the use of special tools.
Use your finger or a small set of bent pliers to pull the
connector toward you in order to fully seat it.

three connectors (A, B, and C). A bi-xenon
headlamp will only have a single connector (A).

position.
4. • If no loose connectors were found and the issue still persists, the issue is outside the scope of bulletin. Do
not proceed with the bulletin. Continue with diagnosis by swapping headlamp components to locate the
failed part.
• If a loose connector was found, correct it and ensure that all connectors are fully seated and locked.
5 Re-assemble the headlamp and re-install it into the vehicle.
6. Clear the DTC(s) and re-test with the low beams, high beams, and all turn signals activated.
7. If the DTCs do not return, test the headlamp functionality with a short road test:
• Repeat the actuation of all headlamps while the vehicle is moving.
• If Audi adaptive light is equipped, test its functionality by driving the vehicle around a corner at a speed
greater than 6 mph (Figure 5).
Note:
Use caution when testing the high beams in traffic; do not create an unsafe condition for yourself or other
drivers.
