Black PCM

[porchecayenne]

Hi, i have an P cayenne 03.

I have a problem with the pcm.

The screen is totaly black. i changed the amp and it worked totaly fine. 3 hours later i went back to my car and its totaly black again ... just spent 1400 euro on a amp. strange that it worked and 3 hours later its not working anymore.

Have checked all the fuses. reset with 1/4/8. lock the car and with inside lock door and all that stuff. still not working.

I live in Norway and its only 3 degrees outside. have readed that some have the same problem when its cold outside. i have borrowed a garage with heat and put the battery on charge. i wil try tomorrow morning.

But have anyone else had this same problem ? i don't want to replace the hole pcm unit that wil cost me another 1400 euro.
