I recently purchased a used Audi A4 and the MMI system does not seem to be working. When I try to access it, the screen remains black and I cannot control any functions. How can I troubleshoot this issue?
ReplyYour MMI system could be experiencing a software issue. Try restarting it by pressing and holding the power button for 10 seconds. If the problem persists, contact your local dealership for further assistance.
There could be an issue with the MMI control panel or wiring. Check for any loose connections or damage and consult a professional for repair.
