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.

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

POST 1 / ORIGINAL POSTEROriginal post

My car (2002 911 C2) was in winter storage with the battery unhooked. Now the pcm 1 is locked. I have the codes to it (one for the interface and one for navi) but I have tried to input them several times but it always come back to the input code sceen. I unhooked the battery last year and I got it to work no problem but now it doesn�t. I suppose I the interface code is supposed to input there first? What to be done?
