Hi all. I have AudiA4Avant 2.0TDleSETechnik Euro5.
The MMI is starting up and then going dark. I have looped the cable in the boot and all dash buttons and screen light up with the loop in. Nav works, heating etc. But anything audio related is down.
I was advised to put in a new unit in the boot which I ordered and did. But nothing has changed.
Desperately seeking advise on what else to test or what to do to get things working again.
Also checked fuses and they are all good.
Many thanks in advance.
