Restore factory settings, computer troubleshooting, repair at 4S stores or professional auto repair shops, etc. Focus on checking touch range calibration, whether the ID of the wireless receiver matches the ID set in the host program, and the distance issue of the wireless receiver. The following is an introduction to the related configurations of the Audi A6L: 1. Safety configurations: Main/auxiliary driving position airbags, front/rear head airbags, front side airbags, tire pressure monitoring device, front seat belt reminder, ABS anti-lock, brake force distribution, brake assist, traction control, body stability control, active braking, etc. 2. Auxiliary configurations: Front/rear parking radar, reversing camera, cruise control, driving mode switching, engine start-stop, automatic parking, hill start assist, variable steering ratio, keyless start, keyless entry system, etc.
When encountering a black screen issue with the Audi A6L, first perform a system reboot by pressing and holding the central control power button for more than 10 seconds to completely power off and restart the vehicle. If the reboot doesn't work, check if the entertainment system fuse in the fuse box has blown—it's located under the cover on the lower left side of the driver's seat. Next, inspect the main unit module behind the left-side trim panel in the trunk, and check if the wiring harness connectors are loose. If all these are normal, the black screen may be caused by a faulty screen assembly or software conflict. I recommend connecting to a computer and using ODIS to diagnose fault codes, then upgrading to the latest system version. In severe cases of black screen, the screen may need replacement or the main unit may require repair, which should be done at a professional service center for proper matching and programming.
My Audi A6L experienced black screen twice, and the issue was caused by power supply problems. First, check if the vehicle battery voltage is normal—below 12 volts can affect system power supply. Then, press and hold the center console volume button for 15 seconds to force a system reboot. If the screen remains black, open the fuse box to inspect the F9 and F10 fuses, and use a multimeter to check for continuity. If the wiring harness connectors are loose, clean the metal contacts with rust remover and reinsert them firmly. If the system is lagging, try restoring factory settings or upgrading the software. If these steps don’t work, consider replacing the screen or repairing the main unit. It’s recommended not to repair it at small shops to avoid module mismatches and new faults.
