Yey, fixed, they took out all the wiring, reconnected it and it working fine again, done a thousand or so miles with no hiccup. All sorted and trucking again... However whislt it was in the garage, I got a company car as my run around was about to give up the ghost so now I am gonnna sell it and make a bloody big loss. Gonna get a Scooby Impreza Wagon when its sold. Bought it for £5,600 now on autotrader for £4,750, new discs and pads 500 miles ago. Very sad, but just want something faster as a second car and the Z3 M Roadster had to give way to my fiancees uni fees for the next two years!
