Caddy ECM coding

[Sam]

Hi, im new here.

Im a mechanic, so if I can help with any technical problems I will try to post some replies.

I have a caddy here, which the engine ecm has been previously replaced before the current owner bought it. However, it looks like it has been incorrectly coded to the vehicle, coded for cruise control (which it hasn't got) instead of aircon (which it has got but not working). Its a 54 plate sdi. Does anyone know what the correct coding (7 digit) should be? or does anyone with a similar van have vagcom and could let me know the coding theirs is showing? or does anyone in the Tamworth area have a similar model (with aircon) that wants a free scan? Also does anyone know what MVB the cts by the rad is? and is it only fitted to a/c models?

Appreciate if anyone can give me any help.

Cheers,

Sam.
