Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

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.

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

POST 1 / ORIGINAL POSTEROriginal post

Hi all purchased a 996 c4 convertible around 8 months ago with minimal history. Pcm has never worked and I did not have the code even if it did. Picked up the codes for radio and nav this weekend from porsche Silverstone and had the pcm repaired today. unfortunately the code does not match the pcm, so possibly a replacement was carried out previously. Could anyone suggest another way of obtaining the codes from the serial number on the unit.

POST 2Original post

Hi Keiran Sorry I cannot help, but I’m sure as soon as Richard sees you query he will be able to advise you. Good luck

POST 3 / ORIGINAL POSTEROriginal post

Thank you for your time

POST 4Original post

If the unit has been changed, I don't think you stand much chance. Because you say 'Radio and Nav' codes, I assume you have PCM1. There are places that decode them, but it really isn't worth the effort or expense: https://www.dndservices.co.uk/porsche_pcm.html PCM1 is now 23 years old. It needs a full size SIM card, which will only work on old GSM networks. The navigation is dire, and you can only use maps that are about 10 years out of date. The FM radio is OK, but who has any casettes they can play? If I were you, I would fit a decent 2-DIN system with all mod cons, which you can buy for not much more than the decoding would cost. Just my 2p's worth.

POST 5 / ORIGINAL POSTEROriginal post

Thank you Richard. Appreciate your advice and I think I will take it. Where do I send the 2p to.[ ]
