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.

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

POST 1 / ORIGINAL POSTEROriginal post

I'm taking delivery of an '02 C4 Cab that has the PCM system. It is coming from the east coast to southern California. Is the PCM software that is loaded for the whole country, or will I need to get software updates for the west coast? If I have to get new software, are these provided for free (the car is still under warranty) or do these have to be purchased? Thanks

You need a new disc, no it is not free, and the "new" version is still from 2001. If you happen to be buying from a dealer, they can throw it in for you, otherwise you have to buy it on your own. I think its around $130.

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