Hello together, since a time the Mini Cooper makes my girlfriend tick. KM-Stand approx. 152,000 km, year of construction 12/2007, engine: N12 1,6l , bought with approx. 128,000km and so far nothing on the chain made, previous owner or car dealer could not give information. Symptoms: At cold start, unsettled idle or strong threshold fluctuations After some kilometers at the traffic light: Sudden speed increase up to 3500U/min up to speed drop to 500U/min or die off of the engine. Error codes read out this morning, but only with Carly: 002968 – intake camshaft sensor : EpmCASI1ErrSig_C: 002982 – intake camswave sensor : EpmCASI1NoSigMax_C: 002983 – intake camswave sensor : EpmCASI1NoSigMin_C: Speed 002B68 – air mass current After I have cleared the errors the mini 25km ran without problems on all speed ranges and speeds up to 180km/h. Also the stop of the engine frequency sensor has stopped without turning.
