Hi everyone, I've recently bought a 2005 Z4 2 litre. Love the car, but I've now got a problem, the windscreen wipers have stopped working, except when I activate the wash/wipe which makes the wipers activate for around 10 seconds (so I know the motor is ok) I've checked the relevant 30amp fuse and thats ok. They were perfect until a couple of days ago, anyone got any suggestions?
