On my way home from work today, I first noticed that my boost was barely building. The throttle was not normal and the car would not accelerate like usual. I then proceed to give it about 80% throttle and boost would build but quickly drop and build again. I decided that it would be best to leave it alone and just cruise the rest of the way home. About 15 miles later, I get a complete loss of power. I had to coast off into the shoulder, which is pretty scary to say the least. As my car was coming to a complete stop, the yellow coolant light lit up. I pulled out my phone to call for a tow truck but decided to turn the car off and back on as a last hope. What do you know, car started right up without any hiccups and boost/throttle response was back to normal. No light or CEL either, maybe from the JB4's autoclear?

-4 months ago, BMW replaced my HPFP with 13517616446, could it have possibly gone bad this soon?
-I have gotten the half engine light before (twice)
-Took it to BMW but they said they couldn't do anything because they couldn't pull any codes.

I did not want to read 55 pages to get an answer so I will ask the question:
How much does the dealer charge to replace the HPFP?
I have 152k miles and I am still on the original pump.

Thanks,

Chris

I just had the HPFP fail on my 2011 335i (super low miles too, under 20K). I find it pretty ridiculous that BMW did not extend the HPFP 10-year warranty to N55 based vehicles, since they share the exact same HPFP part as the N54s.

Dealer quote to replace the HPFP was ~$970. I did check local independent BMW shops, and they ranged from $600 - $800. Hope this helps.

Went to an independent mechanic familiar with BMW N54 motors and they said it looks like an injector and intake cleaning issue instead of the HPFP.
