and the N55 hpfp issues begin

When I mentioned "other bmw cars with N55" I was refering to the 5 series Gran Turismo. But fair enough... that was only released late 2009 I think?

Maybe I was laughing to keep from snapping? Nah, actually it was a half laugh at what the Mustang was doing outside my window. It was just weird because I was already pulled over to the side, and he just pulled out there in the middle of the damn road and starts to trying to launch his car. he wouldn't even look at me...it was actually kinda awkward.

Update
I THINK my fuel has been what is causing my problems. I've always filled up at this one station because it was 93oct with no ethanol in it, and it might very well be exactly that, but I suspect there might be water or other deposits which are fouling things up. It explains why after I filled up I had some horrendous problems and after about a quarter of a tank everything ran perfectly. Looking back on it, all of the problems I had, and them happening so close together makes a ton of sense now.

Why did the dealer not catch this since I've had my pump replaced 4 times you ask? According to the master tech, the way they test the fuel is not an exact science, meaning that they might not catch water or deposits in the very bottom of the tank during their tests. They just draw from the top of the tank where all the "good" fuel was at and never suspected anything was wrong.

I filled up at a new station today that is 93 (but contains 10% ethanol) and I've yet to have a problem. If I get through this whole tank without issue, I think my nightmare is over. Now if you'll excuse me, I need to go beat the crap out of the thing to make sure all is well.

Well, that certainly doesn't bode well.
DAMN.

BTW:
Mike: I spoke to someone relatively high up in BMW Canada and they confirmed that the fuel pumps are similar and the problems will continue. So this is not surprising. There are revisions on the N55 to hopefully mitigate the problems but I wouldn't hold my breathe that this is 100% solved on the N55.

It doesn't sound like Mike confirmed that there are failures. He says that someone "high up in BMW...." confirmed that the N55 uses a "similar" pump. That is not a statement of confirmation on pump failures in the N55. I'm just pointing out what the statement actually was, but, I'm not saying that there aren't failures or that there will not be failures.

Plus, if this "high up" BMW rep is actually saying that since the pumps are similar and "the problems will continue", then it certainly sounds like an admission of fault, if this is actually a true quote/statement and not a paraphrase by Mike.

[boostm3]

Does anybody have a number of failures per number of x35s bought? Not multiple incidences of failure per vehicle, but simply the number of vehicles which have had this problem vs the number sold, to help establish a risk ratio, so that going in, current and future buyers can get an idea of what their odds are of having an HPFP failure at some point during their ownership experience?

I have one on order for delivery in late Oct, and Im getting almost nervous enough to try and back out, even though I love the car (when it is working).

[stevend218]

sooo... why did i wait those several extra months for the N55?....

[Nifty]

My tech told me any car he has put the new 402 HPFP in (that isn't being put into all cars yet because they don't have enough of them) has not had any more failures. Yea, it's just word of mouth, but we gotta keep hope alive!

[FrankiE90]

the OP did not chime back in from the link post.
confirmation has not been made that this is a HPFP problem.
keep'n fingers crossed.

yeah the OP, doesn't post often so we have to wait.

there's a member, shockin330i, that put 10k on his N55 and
no issues for him, yet. He's had his bimmer for month and half.

re-read my post. the threadstarter has updated his post, the dealer replaced his hpfp and put 31 miles on his car.

i said i stand corrected about a different post, where i mis-paraphrased what mike from n54tuning.com had said about n55 hpfp's

[S54dan]

I've been reading this thread, and I wanted to chime in.

First, it's too early to make a determination on if the HPFP problem is fixed. I can tell you that the pump is the same, no different.

I took it upon myself to tally up all sales we've had for HPFP since July 1st, and what year vehicles they were in. Here are the results:

July 2010 sales: 36 pumps
August 2010 sales: 14 pumps

2007 N54: 21
2008 N54: 18
2009 N54: 9
2010 N54: 2
2011 N55: 0

Remember, these are our results. I also think it is not pump related, but the management system.

If true, then we should be looking for relief via ecu flash rather than hardware replacement?

Were these replaced on vehicles bought at your dealership? Do you have any way to correlate number of pumps replaced with the number of cars that were sold in total that were N54/N55 based?

thanks Bryce i didn't see the post.
denial on my part.

that's good to hear Dan@UnitedBMW.

We do, but the rounded number of pumps per vehicle is about 1.

You mean that on avg, every N54/N55 vehicle needed to have its pump replaced? Now I realize some cars may have had anywhere from 1 up to several pumps replaced, which would skew the results.. but even so, it sounds like 'Almost every n54/n55 vehicle sold by your dealership had the malady? Thats not very encouraging. I heard, over all, the percentage of cars that were troubled was still a small percentage of overall cars in this population.. And that there are plenty of cars in this population that have had no pump issues...

Maybe Im not reading your response correctly.

[gnat]

I think he means that at his dealership the average has been that of cars needing a new HPFP, they only needed it once.

Ohh.. What I was looking for was the number of cars affected by failures per the number of n54/55 vehicles sold.

i forget where i read this on this forum, but someone with BMW said that 80% of N54 powered cars produced have had a HPFP replacement

Ouch and more OUCH... was this a reputable source? I can hardly believe this is even remotely close to accurate.. 80% being replaced, since there hasnt been a recall, means 80% of these cars sold have had major problems.. What doesnt compute is that the Consumer Reports april car issue reports that owners of the 135i, for instance, are extremely satisifed with their purchase.. They rate them with a closed orange donut, which is the highest rating a car can get... The definition of satisfaction is, 'would you buy this car again'... It seems strange that with so many (80%) failures, these same owners would be so ethusiastically excited to run right out and buy another...

i'll see if i can find the thread where i read that. it was reputable, i believe.
