Hey Guys. I just picked up a 2007 M6. I took it to the dealer for a pre-purchase inspection before I decided to buy it. All seemed ok until the next day. I drove it home no issues, parked it and went to bed. The next morning I started it up and the fault screen LIT up. Engine malfunction, reduced power, increased emissions, DSC, DBC. I thought WTF! Car obviously went into limp mode and that was that. I had it towed back to the dealership and told them what was going on and that I was extremely unhappy since I only had the car for 1 day. After scanning the new codes that popped up they told me my throttle actuators were dead in both Bank 1 and Bank 2, and that my secondary air pump was also not responding. I bought 2 new throttle actuators and a new secondary air pump and had them installed yesterday. Started up the car and drove it around for 20 minutes or so and had no issues. Faults were gone, all seemed to be ok. Then all of a sudden the engine malfunction fault and increased emission fault came back! Whats going on!? I NEED some help here!!!!
