New M1 & HPFP Concerns

[djspeed_330i]

There seems to be a great degree of enthusiasm in regards to the soon to be released M1 (or whatever moniker they end up going with), but none of the threads happen to mention any concerns regarding the dreaded HPFP issue that has plagued the 335 and the 135.

I don't want to start a forum war, but the HPFP has been quite prevalent. Why hasn't anyone posted any concerns regarding the HPFP issue?

Am I missing something?

I think that is because it's not known yet if the new N55 engine has the HPFP issue? And I guess the N55 will become the S55 for the new M

I've been fortunate to have zero problems with my cars (my 135 has over 25k miles and my E90 has less than 1500 miles), but the myriads of threads about the hpfp are troubling-- especially, since I'm interested in the 1M/M1. I asked Scott about this in the feedback thread and here is the answer I received from him-- I know it might have been a marketing spin but hey...:

my question:

Hi Scott, thanks for answering the questions. I have just one question: there are some 1 series owners-- as well as 3 series owners-- who have experienced hpfp failures, what are bmw engineers doing to ensure that this type of issue doesn't occur with the M1? Thanks.

Scott's response:

I know that this is a problem amongst many members here and I am not entirely certain about the full details. I do know that BMW have spent considerable money and engineering in eliminating this problem. And I am sure the M division will have this at the forefront of their minds when testing the reliability of the new M.

I'm just thinking that if BMW doesn't fix this crap, then I think you may have to think hard if you're better off buying a 2008/2009 used M3 and skip the hassle of having to deal with HPFP.

I guess we won't know if its fixed until they start coming off of production.

On the other hand, there are a ton of unknowns at this point, so I guess its all speculation at this point.

Not negative, just hoping that BMW would come up with a tech solution that would resolve this matter once and for all.

For $40K plus dollars, you gotta be reasonably comfortable that you're not getting a lemon.

This is a major concern of mine as well. Hence I am not jumping on the wait list. I will wait at least a year for any problem to rear its head.

It took 3.5 year for BMW to admit, research and resolve the E46 M3 engine problem and for N54 there's still no permanent solution. This is not just a BMW thing, similar is true any other car companies, (ie Toyota and its sticky pedal) It's simple a price to pay for first movers.

The new one M car might also have a S54 engine too.

Know one know IF it will be N54 or N55.

The HPFP issues are caused by US fuel additives. Easy way to not have HPFP issues is to use top tier gasoline. I use Chevron, solely. Had 22k miles on my '08 135 without an issue, and now have over 6k miles on my '10 without any problems.

This is flat out Wrong! I have only used Shell V-Power in mine, and the HPFP finally gave out at 19K miles.

This has been discussed/argued in DEPTH and has nothing to do with ethenol, additives, or otherwise.

I'm still not going to use crap gas though.

I used shell solely and had HPFP problems. Top tier gas has additives just like any other gas. Additives is federal/state mandated across all gas.

While I believe the failures probably have little or nothing to do with the additives, stmts like this are just as misleading and untrue as the others. You may not want to believe it, but different fuels suppliers do indeed had different formulas and additives. Stick to the things that you know to be facts before you state them as facts.

Now back to your regularly scheduled programming.

I believe he is referring to the fact that US gasoline formulation does indeed have mandated additive packages, which are a base requirement.
Now, once met, gasoline manufacturers can add other things, in various quantities. But, the base formulation of US gas does have mandated regulations, including additives that all US gas must have.

I don't see Roberts comments as not being based on facts.
I think you jumped a bit quickly to with "misleading" and "untrue".
Maybe ask for clarification first.

I guess Ive seen this said so many times on here by the same 3-4 people that I just respond expecting everyone else to know the history as well as I do.

S54 is if I'm correct the E46 M3 engine

[Evice]

This is all speculation and and lots of crying. You do not know the how the n55 will be tweaked. improved or fixed. Give it a chance.

Plus I'd prefer to get new fuel pump over an over again as long as bmwna picks up the tab...oh wait it doesn't matter for me, I have the awesome NA j/k

BOOM!

S55 does have a nice wring to it.

If only BMW had known.

BTW, folks using only Chevron fuel have also had HPFP failures.

It's also with discussions I have had with BMW techs. Calm down dude, jeez...try a little less caffeine in your cofee or maybe sanka.

What I have had explained to me by multiple people in the various tech areas within BMW is that the HPFP has a plastic impeller. That impeller gets eaten away by the extra chemicals in our fuel, chemicals that aren't present in euro gasoline. t's the additives in the US fuel that eat away at it that make it fail. That lil' guy is running @ 150 BAR (that's almost 2200psi to you & me, kids). You get one little imperfection and that pump will no longer be running at such high pressure.

So to alleviate that possibility I have only been using Chevron gas, and I mean only. Never once will I put in Arco, or Costco, or any other type of crap gas. Because all it takes is one tankful of crap fuel and you are screwed.

[ChrisK]

Let's face it, their are multiple factors that cause the HPFP to fail. How do you think the engineers at BMW must feel?

Honestly, I just hope BMW fixes the dash indentation problem before the 1M/M1 goes into production.

Does this appear on the passenger side,top of dash?If it does,then I just noticed that appear 2 months ago...thought WTF!...is the dealer handling it?

...no.sorry,but NO.
I went thru 2 pumps in under 5k.....using ONLY Chevron SUPER!
