Hi I'm very new to all this so if this is all wrong I apologies. I'll get to the point my daughter has an E87 116 2.0L M sport which has brought on the airbag light. put it on the computer and cleared all the the codes relating to the airbag faults bar one which is a 93D7 code. This is a control unit, internal fault, plausibility error. This code will not reset, i checked with my local BMW dealer who is very good and they say they have never had this problem and that if at some time the car had been damaged that the airbag control unit is resetable a number of times. Wondering if anyone has had same problems and a cure.

Hope someone can help
