Another HPFP failure - with BMW tech notes

[lisnter]

Hey Folks,

I've got an '08 135i; build date May 2008; 28K miles.

So I read with trepidation all the HPFP failures. I love the car but was worried about this problem and sure enough, soon after I started to read about these failures I started to encounter symptoms. First, I got a few long cranks and start failures. This went on for several weeks and at my next service I told the adviser of the problem. They reprogrammed my car and I didn't see any problems, though it was intermittent in the first place, but I knew it would occur again. I did kind of notice somewhat slower engine speed increase but the next step occurred before I could convince myself one way or the other.

Sure enough, less than three weeks later I got some mis-fires while driving and the check-engine light came on. This would occur whenever I revved the engine above about 5K. Engine power would die and I could barely make it up even the smallest grade unless I had a pretty good head of steam going already. Sometimes the power would be worse than others.

So, I brought the car in Tuesday morning and got the car back this afternoon (Thursday). My receipt from the dealer has this text:

Good luck. Mine started failing again too. Guess I'll be driving a new 328i loaner again this week.

Yes^^^^ #933 pump is old #880 pump rebuilt..


Maybe a better thread is one for 135i's that have not had HPFP issues..LOL..
Same old story... i just HOPE the new software with all the hardware cures this issue...at least for a year...4 months and counting on mine and all still great!!

My recently replaced HPFP part number is #943 not #933, so what is #933?
