Read evidence and context

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.

Discussions that performed work without a confirmed outcome: 1

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

I think PCM 1 (8 bit) was fitted from 1998, PCM 1 (16 bit) from Jan 2001, and PCM2 from September 2002 (MY2003on).

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.

POST 1 / ORIGINAL POSTEROriginal post

What are the physical diffrences between the two and how does their operation differ? Only reason I ask is I have a 52 plate car registered in Nov '02 and I am not sure which one it is!!

POST 2Original post

PC1 has a separate disc drive and the PC2's is intergrated into the main system.

POST 3Original post

I think PCM 1 (8 bit) was fitted from 1998, PCM 1 (16 bit) from Jan 2001, and PCM2 from September 2002 (MY2003on). You've probably got PCM 2.

POST 4 / ORIGINAL POSTEROriginal post

Definitely PCM2 - now I have to work out how to use it!! Cheers guys [ ]

POST 5Original post

Where are you? There's a nice handbook and I'm sure someone nearby would be prepared to let you look at it!

POST 6 / ORIGINAL POSTEROriginal post

Oh no, I've got the handbook and instructions but I was just trying to "work it out" on my own - not working!! Best get studying!
