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.

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

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 ....
