hi, I have an 2001 996tt with the PCM and I disconnected the battery, but upon reconnecting power, the radio codes in the book don�t work.

No i don't have any documentation that the unit was replaced, but thats the only thing that makes the most sense.

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.

6 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, I have an 2001 996tt with the PCM and I disconnected the battery, but upon reconnecting power, the radio codes in the book don�t work. Went to local Porsche dealer, they gave me codes of what showed in the system, but those aren�t being accepted by the pcm unit. What other codes could the unit be looking for and how do I fix this? thanks -evan Serial number: BE2582Y5007982

POST 2Original post

The radio might have been changed and as such the old codes don't work, beyond that not quite sure. Do you have any documentation that the radio might have been changed?

POST 3 / ORIGINAL POSTEROriginal post

No i don't have any documentation that the unit was replaced, but thats the only thing that makes the most sense. I have the serial, but i think i will call becker tomorrow to see if they can lookup the code based on the serial. thanks -evan

POST 5Original post

You might try pulling the radio. I had the same problem with mine and found that the previous owner had written the code on the top of the radio. He had also hand written it in the book and on the build sticker in the trunk.

POST 6 / ORIGINAL POSTEROriginal post

I have already pulled the unit, several times, to verify that the serial number written in the book is the one that corresponds to that of the unit itself. Amazingly, there doesn't seem to be an easy way to simply decode the passcode based on the serial number. However, my local dealer just emailed back and said that they can contact porsche directly to have them release the code info. So we'll see where that goes.

This is a source reference. Confirm exact model applicability in the original material.
