Question about 2002 Porsche 911

1 Answer

I have a 2002 c4 cab. The radio and navigation schreen is blak and does not work. Took the car in for service at the local porsche dealer and they told me the pcm module needs to be replaced ($3700). Is this common or are they trying to rip me off?

That is the PCM powertrain control module. it usually does not go bad. Most likely one of the components that feed the PCM or that the PCM controls is malfunctioning. Scan for trouble codes to replace shorted sensor as needed.
Get the car rechecked before spending so much.

Let me know if you need further assistance.

Porsche radio code

if you are lucky it is written on the radio, in the service handbook or on the paper sticker on the underneath of the hood. It may also have been input into the ECUs main, an ECU reader may give you this.Falling that there are companies online who claim to decode it for you from the radio s no. I have had varying success, sometimes they work sometimes not. The Porsche dealer may be able to tell you if it is the O/E radio but he may charge for the service.

Porsche PCM Radio & CD Changer Fault.

paul it really sounds as if that dealer is trying to stroke suggestion would to call porshe and find out who the district manager or manager of the stores in ur city or even county and tell him or her of ur problem... and how u feel about this problem.. and ask why a car would be returned to u in worse condition than when u took it there... its very possible that the change of the battery wasnt done correctly and may have blown ur ecu... id get in contact with the district service manager (dsm) as soon as possible..u paid alot of money for this car and for its service.. and should be entitled to quality work performance..
