faulty pcm 2?

[SCOTJC]

Looks like my pcm 2 fitted to my 03 tt has started playing up [] Tried it the other day and for whatever reason there was no volume, but if you pressed a directions button it would give a spoken message so the output was still working. It was then turned off and left for a while and all was fine but now its doing the same again, hit or miss whether you can hear any music/radio but everything else works fine. Anybody any ideas? Pretty sure this isn't covered by my porsche warranty so sitting here full of dread[&o]

An extract of a TSB is shown below. It doesn't sound exactly like your problem, but the software update might be worth trying. If you want the whole thing, drop me an email.
