2 Answers
The reasons for the Audi A6 display screen not lighting up are as follows: 1. Poor contact: There may be loose connections in the vehicle's wiring, which requires timely inspection for any weak connections. It is recommended to securely reconnect any loose parts. 2. Signal wire aging: The power signal wire of the vehicle may have aged. Try replacing it with a new power signal wire. 3. Power supply module failure: Prolonged use of the screen may cause the power supply module to malfunction. It is advisable to have it checked or replaced at an authorized 4S dealership. 4. Unreasonable circuit design: There might be defects in the circuit design. It is necessary to have it inspected and repaired at a maintenance shop or simply replaced.
I've driven an Audi A6L, and the display not lighting up is quite common. First, check the fuse issue—inspect whether fuse F46 or related fuses in the fuse box under the glove compartment are blown, and replace them if necessary. Software glitches can also cause a black screen; try restarting the system by holding the volume knob for 10 seconds or disconnecting the negative battery terminal for a few minutes before reconnecting. If the problem persists, the display itself might be faulty or the wiring could be loose, requiring professional diagnosis. The air conditioning and navigation functions are significantly affected, making it quite dangerous while driving. It's advisable not to attempt disassembly yourself to avoid triggering more faults—getting it checked at an authorized service center is more reliable. Regular maintenance should include monitoring battery voltage and system updates to prevent many electronic issues.
