Guess what? My 2009 M6 has been serviced and has always been under warranty with BMW. Now I am at just over 100,000 and have a major engine fault. I am told that BMW NA will not do anything for me. Is there anyone that has had an experience with getting some help with a similar warranty experience? I am told that the Bank 1 actuator is faulty on my 2009 M6 with a $2161.99 cost. There may be more to this error as well. Very frustrated. Any suggestions??
