Sheriff> Thanks Derek, I looked at the switches and there were no Sheriff> obvious signs of faults (loose wires, burn marks etc.).
Sheriff> BECM. Are they standard across all P38s? Mine is a 98 Sheriff> 2.5DSE and there are a few on ebay ranging from £120 (on Sheriff> auction) to £500 (buy it now).
No, they're mot all the same, but they did standardise on later models. I don't have the parts book to hand to check.
HOWEVER, if you put a programmed BECM into you car it will lock out the engine until it's recoded, refused to work with the central locking, and possibly increment the mileage on the odometer.
You need to make sure it's a cleared out BeCm (there are people who can do this) or that you get it cleared before fitting. You will also need access to a diagnostic system to program in the new lockset code, other vehicle settings, and the engine ECU to accept the new security codes.
