There is no indication that U.S. fuel has anything to do with the N54/N55 HPFP failures. As reported the pump failures exist in all markets world wide on the N54/N55 engines including on the 2011 models. Use the forum search option.

...I beg to disagree. There are people reporting 2-3-4 HPFP replacements while many others (like me) don't seem to have any issues. I know for sure in EU the HPFP failures are a rarity, I have a friend who runs a good size BMW dealership/ Service there and while he has been notified about the "problem" he hasn't seen a defective HPFP pump yet. It's true, E9x with N54/N55 are quite rare in EU but he sells and provides service for a large number of 5 and 7 series fitted with these engines.
What I've noticed is that - when questioned - people with HPFP problems tend to recognize they don't use good quality gasoline or at least not all the time.

Not quite that universal. I never used anything but Shell 93 and had two failures in a little more than 2 years.

Nothing but top tier 93 or greater for me. Mostly Shell. I do live in one of the ethanol hell areas but there's no concrete evidence that ethanol is indeed the cause.

I've had five failures. There's something specific about my car that causes it to chew up pumps and injectors. Many people report zero failures and there seem to be a few people like me who have a lot, so it really makes me wonder... It's like some cars are just more prone to failure, but in today's world I don't see how that's possible.

...I would believe that I am the only one struck by luck - again, I am on my second N54 (I do approx 20K /per year) - and no problems with the HPFP ... but apparently I am not ...my brother drives a 535 fitted with N55 and no problems so far. Also check here http://www.e90post.com/forums/showthread.php?t=613143. I still believe that having to replace multiple HPFPs has to do with some pattern ...have no idea what goes wrong. I would suspect it is the gasoline since EU doesn't seem to have the same issues...but I am in NA, I am not pampering my car, it is used daily in heat,rain, snow and on some quite bad roads here in MA. The service is also very bad compared with anything in EU (cleanliness, technical knowledge, tools etc)

...missed to add ...I feel you pain, if i would be in your situation I would be quite upset...obviously.
The only pattern I've noticed remains the gasoline...maybe it's not the about the brand... I don't know...I only use 2 gas stations that are very busy (have a high turn around) and I have the tendency to keep my gas tank close to full especially in the cold season. All my cars are/have been driven hard, the 2006 335 (a lease) actually endured some very tough treatment... flawlessly. I wouldn't have purchased the 2009 E92 otherwise. My brother who currently owns an F10 535 and and an X5 does the same...lives in CT, lots of miles every day and night ( doctor) , skiing trips, taking constantly the kids to sport events out of state etc. Our BMW's are not garage queens....again, no HPFP problems.

...so you don't own a BMW with N54 but you know "is cursed"...I would call this e90post.com induced paranoia...
If you plan to buy a Toyota ...their new generation of engines that are currently in development are all ... DI and turbo. Enjoy.

That's good to know. I am buying a 335is and hope I have the same experince as you are having. I have been driving a 2004 E46 330i ZHP for the last 8 years with no problems.

[BuraQ]

Once I strongly believed it was tune related for those tunes that cannot modify returned fuel mixtures while running higher boosts. I am not still not 100 convinced that it is not.

However I do believe fuel in general is the real culprit of the type oc octain and quality fueling the car.


I am nearing 12k miles on my 335is, no issues and I ride the hell out of this car.

I think you completely missed the point.

By quite a margin in fact.

Good Lord... this forum sucks.This is my last post. Adios.

[randoncoffey]

7k miles. Engine cranked for 3-4 seconds before starting in the am for the first time. Normally starts immediately. On the way to work I was driving at 30mph when I hit the accelerator and the car shook violently. Engine Malfunction, Reduced Power message came on - any ideas? Taking it to the BMW dealer tomorrow but wanted to know what I'm in for. Had a 2008 335i for 3 years and never had a problem. Any help would be great.

[MiniMotoMan]

I bought my 07 used, and didnt know about the hpfp issue till after I started having a problem. It never left me stranded just long starts and limp mode, so I replaced the hpfp myself and had done some research by this time. I have never taken it to a dealer so I dont know what software I have.

Heres what I do....

When I unlock my doors with the remote I can hear the lpfp priming. I put in the key and put on my seat belt and by that time its usually done priming. THEN I start the car. I dont not start it until after its done priming. I havent had any problems for about a year now and I drive 60 miles a day round to and from work. And plenty of joy riding on the weekends. Now if Ive been driving and pulling into the gas station then get back into the car sometimes it doesnt prime, its still holding pressure because it didnt sit that long.

Its a minor inconvenience and I dont think its something that I should have to do especially on a higher end car but oh well. They should program it so the car wont start till the fuel system is primed. That might save BMW some headache.

Anytime the engine malfunction error comes up you should take it to the dealer. Restarting the engine usually makes it go away temporarily, and appear like everything is fine. If you do not act on the error, it will progressively get worse, and then probably leave you stranded.
