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.

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

POST 1 / ORIGINAL POSTEROriginal post

My PCM 2.0 Nav HU has been dead since I picked it up from the Port. Fuse is good - any thoughts. The car is CPO but I don't mind getting my hands dirty...

Did u check the fuse at the back of the body of the PCM 2 ? My PCM 2 was dead after a jump battery start and it was this fuse which was burnt . Hope this helps see ya all and have fun

POST 3 / ORIGINAL POSTEROriginal post

Great tip - I'll try it tonight. Thanks!

POST 4 / ORIGINAL POSTEROriginal post

I did not realize it was so wasy to remove the PCM! I replaced the fuse and now the nav works but it is not registering the cd changer and the amp. Is there another fuse that I should be checking?

POST 5Original post

Off topic - but does Porsche recognize the US CPO in Germany? Logic would dictate ... Stefan

POST 6 / ORIGINAL POSTEROriginal post

Yes but it only one year vice 2 in the states. Where ever the car is the country that the service is provided is the policy that pervails.

POST 7 / ORIGINAL POSTEROriginal post

I'd bring it in for service but I'm off on a three week trip. The sunroof also need to be worked on. I've only had the car a week and driving it is far more important!

POST 9 / ORIGINAL POSTEROriginal post

I found one and replaced that one - did not even think to look for a second! I guess she will come out again!
