I've just picked up a 2008 535i with about 32k mi's on the odo and am concerned that with all the complaints about the High Pressure Fuel Pump (HPFP) , that my car will NOT be reliable. When I asked the dealership about this, they assured me that BMW has resolved this issue and that my 535i should run withou issue. The salesperson who I dealt with said that she would look into this concern and whether or not my car has the latest upgraded HPFP installed or not. So instead of being glad about my new Bimmer, I'm very concerned about whether or not this car will be reliable - especially when it comes to this pump. From some of the other forums I've read about this issue, the recommendation is that I only use high quality gasoline from national brand such as Shell or Sunoco. I also take it that I must use 91 Octane gas minimum for this car. Should I be concerned? I have the remainder of the 4yr/40k full coverage warranty left and will probably purchase an extended warranty when the time comes. I would appreciate any advice on this issue. Thanks, Keith R.
