Can anyone help? I discovered brake fluid pouring out of my pressure differential warning actuator valve this morning. On closer inspection it was coming out of the bottom of the electrical switch [the terminal end]. A quick trip to my Land Rover dealer to buy a new switch which I've just fitted only to find fluid leaking from the same place. I'm puzzled - if this is just a switch how does fluid pass through it? It has a small plunger at the end that screws into the p.d.w.a. valve - presumably to make the electrical connection. Its part number is AAU 1700.
