| Fuel Pump problems |
Hard to start, cranks for a while till it builds up pressure then starts. Idles rough and sometimes dies when sitting at stop light, and sputtering power at time when taking off, leaks fuel from right rear wheel well when filling with fuel. Also stalls while driving and total loss of power for steering and other controls, very dangerous when it occurs. I'm told it is the high pressure fuel pump and I must say that I cannot see how this part can be so expensive ($2,700) and surprised that BMW did not recall these and replace if this in an endemic fault. I was lucky that my car failed 20 yards from my house as I returned from a 200 mile round trip on the highway. I dread to think what might have happened to me if this had stopped while I was on the fast lane of the highway. For what is a flagship car, it is a potential death trap.
In reference to BMW 760li fuel pump. Recently had to replace mine, after car stalled while driving on the the highway. Car also was hard to start, had to crank along time to build up enough prssure to start. Problem became worse over time.
The contact owns a 2004 BMW 760li. While driving approximately 70 mph the vehicle suddenly stalled. The contact was able to merge to the side of the road and restart the vehicle. The vehicle stalled approximately five times intermittently. The vehicle was taken to the dealer where the technicians stated both high pressure fuel pumps needed replacement. The vehicle was not repaired. The approximate failure mileage was 49,000.
