Half way to Super Sausage cafe for Porsche meet today and I,m driving along the M1 when suddenly ping and I lose the sat nav display, CD and blue tooth phone connection. The PCM 3.0 (2010 Cayman S) is totally dead. I have removed both fuse 9 and fuse 10 and checked them, they are ok.
Tried key 2 but it is still dead. Is there a Fuse in the back of the PCM itself ? If I select Nav, Phone, Audio on the stork selector switch the message Nav fault, Phone Fault or Audio fault is displayed.
Any help would be much appreciated.
 
Are any other systems effected such as lights, chrono pack if you have it or hearing/ air con? Just in case there is a system type fault?

Took the Car to Porsche Wolverhampton and after 4-5 hours they told me that the whole PCM would need replacing and then reprogramming with the 7 digit post code which I would have to pay for again.

Total cost of £2020.00

After some phone conversations to Avril, she managed to get the price down to £1025.00 and finally after another call got the price down to £395.00 including the 7 digit codes being installed which I think was excellent and a credit to Avril and Porsche Wolverhampton for fighting my corner with Porsche Germany over 3-4 days.

The following Monday / Tuesday the new PCM was fitted (Due to the software this took over a day and they provided me with a car that I could use in the mean time) and all is good so far although I have only driven back from Wolverhampton.

For anyone else who has a PCM problem they might want to give Charles a call at BBA REMAN Rochester on 01634 687222 who charge £75 for having a look at the PCM and if they can repair charge £175 which includes the original £75. I was going to go this route but then when Porsche came back with £395 with 2 year warranty, the Porsche route was a no brainer.

 
The only things effected were the PCM which included the sat nav, radio dvd, phone. Basically anything controlled through the PCM. Unfortunately none of this was covered by the warranty given by APEX Motors Swindon who I bought the car from some 7-8 weeks earlier.

One strange thing is that for a while when on route to Wolverhampton the PCM kept trying to fire up.
