Thanks for the information hopefully i can come up with something from that,
The Ford Galaxy came fitted with the VW tdi as the car was a joint venture with VW, so its not a conversion, and in the uk they didn't force makers to run OBDII till alot later, something like 2006 IIRC.
Now all i need to do is read up on how to make one of these MPGuino and program it. Should be fun
