My wife's MK1 Golf Clipper Cabriolet is idling high, and 'Dieselling' or over-running. I'm told this is either the Pierburg Carb in it, or the coolant temperature sender. Am I right in thinking this is a green 2-pin sender?
if it is idling high and running on it will almost certainly be the wax-stat stuck on the carb common fault and an easy one to replace the part, it is held on the front lower of the carb by two phillips head screws and has 2 water pipes going to it replacements are still available
hmmm. I changed the Waxstat for a working spare I had here, and it's still idling high, and running on.
I'm guessing it is the coolant temperature sender at fault after all. Could anything else be causing it?
