I`m hoping someone on bimmerforums can help me out a little. i bought my car over a month ago, at first it cut out on me, periodically, once every 2 days. the cut out would happen both when i am driving and stationary. all the dash board lights come on, including ASC and the temp gauge goes from the middle to red. on most occasions the car starts fine again if you wait a few moments. and none of the dash lights remain.
i took it back to the dealer they looked at it and changed the cam sensor which was faulty and apparently causing the cut outs.
So i get the car back drive it and notice in idle, the car revs by itself now, hits just under 2000 revs, it goes up and down repeatedly, but when i turn the air con on it will stop revving by itself.
the day after getting the car back i go to start the car and it will not start. same thing as before with the cut out, all dash lights come on temp gauge hits red and stays there.
i took it back to the dealerships mechanics again, they apparently could not find any fault with the car, and assured me the car would not cut out whilst driving again and they were clueless about the revving, they said they hooked up to the diagnostic machine again and no error codes came out.
well i have had the car back just under a week and today whilst driving, i`m in 3rd slowing down for a mini roundabout and it cuts out. after a few moments it starts again.
any ideas please?
