I've just purchased a 320D M Sport (2008 LCI)and its got a problem with the seat. The backrest side supports keep pumping up on it's own, I have to move the seat around (forward back / up down) and find a position when you can hear the pump stop.
It sounds like I wiring fault, but I dont have access to any wiring diagrams on this unit so dont know where to start. I was hoping as a short term solution I would be able to unplug the switch or the electrical connection to the pump unit I get a time to look at the wiring properly.
Would really appreciate any suggestions on how to diagnose this or get access to a wiring diagram so I can investigate.
