How to Fix the MMI Display Screen on an Audi A4?

I recently noticed that the MMI display screen on my Audi A4 has stopped working. How can I fix it and get it back to its original working condition?

The first thing you should try is to reset the MMI system. This can be done by holding down the function keys for 10 seconds until the screen goes black. Then release and wait for the system to restart.

If resetting the MMI system doesn't work, there may be an issue with the system's software. In that case, you will need to take your car to an authorized Audi dealer for a software update.

Another possible reason for the MMI display screen not working is a faulty connection or damaged wires. Check the connections and wiring and repair or replace them if needed.
