Injectors, spark plugs, and low pressure fuel sensor are malfunctioning and need replacement. $3,000 is what they are asking for. Bunch of no good scam artists. They messed up my car. I had no such issues prior to dropping it off for waste gate fix.How could all these parts go bad when the car was off and on a lift the whole time? Contacted BMWNA about this before I storm back in to dealership and end up making the local news.
Seems awfully sudden...but have you had the intake valves cleaned?
