Technical Background When opening the rear lid on the Q5 the rear lighting changes from the rear lid to the bumper and when closing the rear lid the lighting changes back to the rear lid. The two micro switches for the reverse light change-over are under the loading sill cover on the rear cross panel and are secured to the striker for the rear lid lock (Figure 1). The following problems can occur: 1. The paddle on the micro switch was broken due to the adjustment of the rear hatch or the striker in production. 2. Dirt can block one/both paddles on the micro switch, which is fastened to the striker of the rear lid (Figure 2). Figure 1. Rear lid closed sensor. Figure 2. Debris trapped in the rear lid closed sensor. Page 2 of 4 © 2021 Audi of America, Inc. All rights reserved.

Production Solution 1. The adjustment of rear hatch has been optimized. 2. The rear lid closed sensor assembly with an additional enclosure to protect the switches from debris ingress is now installed. This improves the debris resistance of the switches but cannot eliminate it entirely. Service 3. Replace the rear lid closed sensor if found broken (Figure 1). 4. If debris is found to be obstructing proper switch activation/deactivation, activate the switch paddles using your fingers and remove the debris. Using compressed air is effective. 5. Then check the measuring values for the G525 and G526 switches and replace the rear lid closed sensor if the malfunction persists. Only the improved rear lid closed sensor with the protective enclosure is available. Warranty Claim Type: 110 up to 48 Months/50,000 Miles. G10 for CPO Covered Vehicles – Verify Owner.
