I see... I guess it doesnt always have to happen 200 miles from home when youre going to some important appointment or something..... Do you know what years their 135s were?

Both are '09s.
Also, from what I've been reading, people are getting symptoms days/weeks ahead of the HPFP completely failing so the car is still drivable until you make an appointment and drop it off at the dealership. It won't happen suddenly and leave you stranded.

So as I got my recall issues fixed with my 135, I asked my SA regarding the fuel pump issues. He told me that they have a fix which took a long time to come by and will begin recalling fuel pumps in batches. I asked him when they figured out a solid solution for the fuel pump and he told me 2 months ago. It had something to do with the original fuel pump maker doing a crappy job and when BMW tried to find out what had happened, the company had jumped ship leaving BMW with a crappy fuel pump and no solution. He gave me more details, but that is the gist of it. Also, the recall will be in batches due to the # of fuel pumps which need to be replaced. Maybe he is referring to the 402 HPFP? IDK. This was just last week when I spoke with him. Truth to the story; possibly? Regardless.... all we can do is wait.

My 135i hasn't arrived yet, but when it does I hope to go through at least three HPFPs, and hopefully at least 1 reach around from BMW in the process

No issues from mine yet, but it was naive to think that the N55 would solve it all, given that the HPFP was the same as in the N54. It was a good opportunity to have some enhancements that would be an incremental benefit, and that was my logic in getting my 2011...
I hope to never have an issue, and I do actively use fuel adds and optimize my fuel and oil chemisries as best as I can. Maybe it will help, maybe it will not - time will be the only teller. But no need to laugh - everyone ALWAYS was in the same boat. Even if there was a perception of something else. It is in BMW's best interest to make this a fun, efficient, reliable engine. |

I believe I was the first. My tech told me this same thing back in May '10. But, he claimed that the pump had already been made by then. Your dealer says "2 months ago", so that's different. The rest is about the same. This will NOT be a "safety recall" issued traditionally by the NHTSA. It is a BMW internal "recall", and they will be notifying owners in "batches". I do hope this finally comes to fruition. I've got nearly 12k miles on my '09 135i, and I have not had a failure. But, that doesn't mean I will never have one, nor does it mean I will. Still, if BMW has a pump that they KNOW will not fail, or at least not at this level, then I WANT it. I also want a proper software update!!! |

Not necessarily.. The N55 could have been a partial response to the HPFP failure issue; a failed response. I doubt it was the primary reason for the N55, as I think economy had alot to do with it, but just because an item fails doesnt necessarily mean what you say. Only if you had adequate numbers and length of time to judge, might you begin to try and make a determination.. And lastly, result is a poor indicator of intent.

I just got my car back from an effin HPFP
This is the nail in the coffin for me. These guys are ignorant morons who are incapable of engineering beyond a certain point. I went through this shite with my E36s and subframes, then water pumps... It never ends!! DONE. If it weren't a lease, it would be gone already

Plus, the fact that they used the same pump speaks more to a bad decision on the fuel system parts. If there were any intent to develop a new engine to combat a poorly designed part or system, one wouldn't then use a same or similar part in the new engine. It's quite likely the N55 project was given the green light before the full extent of the HPFP issue was know. By that point they/BMW probably had to go with what they had already designed. Yes, in retrospect, it is a bad decision, but it also shows that the N55 wasn't in response to a known bad part or system. For me, IMO, I don't see how the new engine is in any way an attempt to fix the N54 HPFP issue. |

What I'd like to know (especially since I just ordered one) is for the N55 pumps that have failed, which pump did they have?
Supposedly the new "402" pump is supposed to fix the problem (not holding my breath), so it would be useful to know when/if these pumps start failing. But of the 2 N55 failures I've seen posted about, I haven't seen it said what the failed pump was. I will not have HPFP issues. I will not have HPFP issues. I will not have HPFP issues.... |

nobody has had a 402 failure. (at least not in any of the 3 forums I hit)
I posted a poll a while back asking (as I was about to get a replacement on an 08 135) and nobody that's had the 402 has gone back for another and several have several thousand miles on them now. Three dealers here have put several in and none have come back... And if you read through this post, the problem suggested at the start was another N54.... so far there is the suggestion of a single N55 failure on another forum... personally I look for better feedback than that before I start chirping like a school girl. Frankly, people with N54's should stay the f*** out of this thread and post problems in one of the bazillion n54 threads. That's the only way to keep any relative track. |

The 402 could solve the issue, but believing it does could have the same result as believing the N55 fixed the issue. Quote:

This is why I think it is important to know which pump is being replaced on the N55. |
