I have a passat SE TDI 02. I need to replace the coolant sensor which is in a tricky place at the back of the cylinder head and down quite low in the engine. I can only get one hand on it, but it will not pull straight out. I need to get a screwdriver or something in to disconnect the wires before removing the sensor which is held in by a clip. Somewhere else on the engine, no problem, but this is tricky. Anyone got any bright ideas or tips. Thanks.
