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.

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

POST 1 / ORIGINAL POSTEROriginal post

I tried looking through the archives and it looked maybe Tequipment was going to have instructions but the topic sort of fizzled. If I buy an 03 coupe without PCM, can I add it? or is it an enormous pain, as the previous year cars are? Thanks for anyone who has info...

POST 2Original post

mkh, save the headache and just get one with the PCM...other option, scratch the PCM and a Traffic Pro...

POST 3Original post

HI, did you ever end up doing this upgrade to the PCM 2? I have an 03 c4s without the PCM and I'm trying to install a PCM 2 but I have NO idea what I need, what I'm missing, etc. any help? Jon, [email removed]
