Bandit Happy Easter all .
My PCM unit keeps turning on and off with the Porsche logo coming on , even after the keys out it can turn on and off , but when I lock the car it goes off . Been told it need's an earth check or even a new unit . Disconnected the battery for several hours , then it all worked fine for a few days and then started again . I first noticed the problem when I had a new battery lead fitted , did the number code but no use , to me it feel's like it should be reset . it's a Porsche 997 Carrera S 2007 had it for over 6 years virtually fault free . I'm in Kilburn , London , NW6 anyone near who is expert in this . Cuba Bandit

Seen it a couple of times many years ago .. from memory it was always a new head unit , might be a software fix these days but thats OPC only for that .

Either way a fault code read out might be in order to prove its the unit .
