Technical Service Bulletin Connector “A” (Figure 2, A) can be seated but not fully engaged. When pushing on this connector the projector will swivel, thus you will need to hold the projector housing when applying pressure to the connector. Figure 2. Connector “A” shown not fully seated. Connector “B” (Figure 3, B) can be fully locked into place but it can be rotated 510 degrees off center. Thus, please check to ensure the harness connector is seated parallel to the connector housing on the headlamp. Figure 3. Connector “B” shown off center. © 2013 Audi of America, Inc.

Technical Service Bulletin Connector “C” (Figure 4, C) is located behind the motor mechanism, which rests below the projector lens. This is a very small two-pin connector. Take care when wiggling this connector because if it becomes fully disconnected, it is very difficult and almost impossible to reconnect without using special tools. Place your finger, or a set of small bent pliers, on this connector and pull towards yourself to fully seat the connector. Figure 4. Connector “C” shown in the locked position. 4. Ensure all the connectors are fully seated and locked. If a loose connector is found, skip step 5 and move to step 6. 5. If no loose connector is found and the issue still persists then the issue, is outside the scope of this TSB and the remaining steps can be skipped. A swap of headlamp components between left and right is the next logical step to narrow down the failed part of the headlamp. 6. Reassemble the headlamp and install it back in to the vehicle. 7. Clear the DTC(s) and retest with low beams activated, high beams activated, and all turn signals activated. 8. If no DTC’s return, test the headlamp functionality in the garage or parking lot but also perform a short road test and repeat the actuation of all headlamps functions while at a speed. To test the adaptive light function (if equipped) the vehicle will need to be driven at speed around a corner at a speed greater than 6mph. Note: It may be difficult to use the high beams while in traffic; therefore, please use caution and do not create an unsafe condition for you and your fellow drivers. © 2013 Audi of America, Inc.
