Hello. I have problems with my 2004 530i. The engine is very unstable, when I accelerate the car do not respond. My scanner deliver me this codes:
28B3, 2740, 2787 and 278C. I hope somebody can help me.
Thank you very much and have a great day.

Welcome to the Werkz.
Try disconnecting your MAF and see if it makes any difference. I had similar issues with my E38, particularly when it was cold. I ended up changing it, but disconnecting helped to pinpoint the problem.
