Hi all,
I have an issue where every now and again my HUD just stops working. I use INPA to read and then clear the codes and this fixes the issue for a few weeks but clearly there is an underlying cause...

I get the following codes when I read:

A398 - TCU:Fault, microphone 1 or VM: Control module: internal fault
A38F - VM: Receiving system, supply voltage: outside tolerance
E1CF - No message, receiver CCC/RAD2/RAD1, transmitter instrument panel
A554 - Message error (telephone, 0xC1H), receiver instrument panel, transmitter JBE

Other possibly associated issues are:
- DVD player and TV do not work (but Nav system does)
- Cannot update the nav system at all

Has anyone seen anything along these lines before?

Any help greatly appreciated.

Cheers
