Well I had an interesting problem today - driving home in the pissing rain down the M40 when PCM decides it's had enough and switches itself off...

30 seconds later, switches itself back on again - Porsche screen comes back up and back to the Trip screen then the whole thing freezes. No trip, nav, audio etc. Then it merrily switches itself back off and the whole thing repeats again.

Have about 2 - 3 seconds when it first boots up before it crashes so managed to switch it off.

Anyone experienced this? Any suggestions as to cause / remedy. I've had the car 4 months (bought second hand) and it has performed faultlessly.

Only thing I can think of is that water getting into PCM / DVD compartment as it was very wet today.

I had it happen once. I thought there was a short of some sort, so I left everything off until I got home. After letting the car sit overnight, I've never had the problem come back. Good luck ....
