I own a BMW 335 XI and I had the problem of the high pressure fuel pump going out on my vehicle. When I took the car in the Winslow BMW in Colorado Springs they told me this was a rare and uncommon problem with this model. I was going to make a lane change and almost got hit in the rear because of the power loss. The car was very sluggish and non-responsive. I would like more information on this and any contact information you may have to get the problem resolved.
