My G plate 2wd sapph has just failed its MOT on an "abs pressure compensator" that is located under the rear of the car. It comes off the T piece pipe that is bolted to the floor pan and comes down the left hand side of the car with thew fuel pipes. It is about the size of a lighter. Anyone had a problem with these? and where can i get one fords no longer do them. I am desperate for this part to complete MOT. Help anyone
