Mein Auto: 2012 Dinan Stage 2 550xi
Well sports fans, this morning I got my car back after six days. The verdict on the problem was permanent fuel injector malfunctions on all cylinders. As a result, they replaced all of my fuel injectors. We will see if this was in fact the cause of the problem. I'm not so sure. I certainly hope it was.

It sure is great to get back in the 550xi after six days in a runflat tired 535. Besides the runflat tires which seem to ruin the ride I certainly noticed a very strong throttle lag delay. The car I had was an early build 2011. Also I didn't really appreciate the extent of the traction advantage of the 4 Wheel Drive until I drove this rearwheel drive 535. On a number of occasions when accelerating both from a light and up some steep hills, the traction control light in the 535 came on cutting power. Basically that has never happened to me on the 550xi.
