Hi,

I’ve a 2006 3.0 TDI Q7 with Bose sound and basic MMI with sat nav DVD. Last week the radio sound cut out which also affected CD sound. CDs played but no sound. Sat nav sound was fine. After parking for an hour it worked fine from starting. Next drive was fine, but since Sunday it cuts out after a few minutes, and last night it cuts out after approx 1 second of ignition key insertion. Pull key out and back in and I get a quick snatch of sound before silence.

It feels like a a loose connection is tripping something but not seriously otherwise I’d expect a fuse to pop.

I haven’t tried a reboot or fuse disconnect hard reboot yet so all suggestions much appreciated.

It may be unrelated but the power steering pump blew last week and spewed Auto transmission oil over the engine bay. The pump has been replaced and the problem started first drive since collecting from garage.
