hi all, im having some serious trouble with my 3 series tds! i was driving home from work on friday and the bloody thing started to accelerate on its own! let off the throttle and it just hit the ren line and stayed there! switched it off and back on again and it was ok untill i touched the throttle pedal again. iv changed the potetiometer thats connected to the pedal but its still the same! any ideas?? maybe the fuel pump?? i know the pump is fly by wire and wondered if its an electrical fault??
