Suggestion

If your radio powers up and asks for a code but the code is not working, I would check the code on Renntech.org.

Might try another battery disconnect and/ checking of the code with Loren at Renntech.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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.

10 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

Hi, The battery has been disconnected from the car, but now when it is back again, the radio is gone ! I have entered the code for the PCM, everything is working, telephone, navigation etc, but the radio is completely gone. Any ideas or someone who has experienced something similar ?

POST 2Original post

What year is your car? If yours is before 2003, how did you enter the radio code if completely gone? If completely gone and does not light up with power button, it has a separate fuse to check.

POST 3 / ORIGINAL POSTEROriginal post

The year of the car is 2002. When powered up again it asks for the PCM code and I entered the code. The fuse is ok.

POST 4Original post

If your radio powers up and asks for a code but the code is not working, I would check the code on Renntech.org. They have a thread where Loren will find your code. If your radio is now powerless see this thread for a second fuse behind the radio: http://www.renntech.org/forums/topic...radio%20+codes

POST 5Original post

I had this happen, and I called a Porsche dealership and they walked me through pressing a few buttons which revealed the stereo's serial number, and then they were able to give me the correct code. I believe after you punch in the code, you have to hit the down arrow seek button to enter it. Swaff

POST 6 / ORIGINAL POSTEROriginal post

I already have the correct code .. Everything in the PCM works, but the radio is completly gone :-S If I push the Cassette button it says 'no cassette' even though there is a cassette in - if I push the CD button it says no 'CD PLAYER FOUND' even though the cd player is loaded .. If I push the Audio button the screen is almost blank.

POST 7Original post

So you have power but no function. Might try another battery disconnect and/ checking of the code with Loren at Renntech.

POST 8 / ORIGINAL POSTEROriginal post

Already did a couple of times .. No luck :-(

POST 10Original post

Took it into a specialist - alternator replaced
