One of them is your HPFP telling you it's got problems. Specifically that the pressure is too low.. I got these two codes a week or so ago. They are both shadow codes

this is very good info.
-do you know the model number of your fuel pump?
or when the production build is for ur X5?

Ton's of internet-sized rumor an innuendo so far, but not too many confirmed cases.

There are sufficient confirmed cases that it is obvious that the problem has NOT been fixed for early 2011 builds.

True but it's also obvious that there are a lot of sky is falling types posting here as well. I remember with fondness the thread by the guy who RAN OUT OF GAS! His whole guess what my car died post clearly insinuated hpfp failure. I would love to get an idea of how prevalent this problem is and whether or not that prevalance has dropped since 2007 but based on this forum and others, I have no idea.

My x5 was ordered July 2, Delivered by July 29th (2010). Not sure on the model number of the pump, but I'm sure it's probably a 943... I check every week now, and clear the same codes everytime... SO I know one of them (or both) is HPFP fault codes. I only pop those codes when I get a long crank (3-5 seconds) and the RPMs are rev-ing all the way up to 1500-2000k upon start-up... Same exact issue I had when I was driving my 335 (and that had two HPFP failures/replacements)

[ThreeseriesFTW]

The HPFP is primary reason I bought my 335i

I remember five years ago, freaking out that BMW was coming out with a twin turbo. It was one of those unicorn cars I would never be able to afford. But then my 325 died a month ago, so I went to Carmax to look for a replacement and I see a fully loaded 335i for a little less than half of the original price. It cost less than my 325 had. I asked the salesperson why a low mileage 335 was so cheap. She only gave me the usual "our cars are better priced" sales pitch.

So I searched long and hard, and found out that consumer reports gives it like...23 out of 27 worst reliability ratings because of the oil cooler and hpfp. During the course of the research, I learn to check for the oil cooler before buying (found it!) and I found out the HPFP is being recalled in December 2010. SCORE. So I decided to buy it. A low mile fully loaded 335i for half the cost, with a fix for the main issue just a month away.

Now if I can only make it a month without the HPFP failing, I'll be good to go.

Don't count your chickens till they hatch, this RECALL has been public news for a month or so and some members on here have already gone in for a replacement of this miracle fix all HPFP, and low and behold, they are getting the same pumps that may have failed previously... Hell as stated above my N55 X5 was built in July and I'm starting to have HPFP issues already.

I won't believe that they have created a fix all pump until we stop hearing about HPFP failures

Lol u should have researched a little more. There is no fix.

As the starter of this thread, I can chime in on a few things. There definitely is no permanent fix for this issue yet. While the incidence of occurrence may have gone down, it does not mean that the problem is permanently fixed. I don't think anyone can make the claim that BMW has a permanent fix until we all get the new fuel pumps and drive on them for a few years. If only a few pumps fail; then yes there is a permanent fix, if they fail left and right then clearly it has not been fixed. In my situation, I had my pump fail at 1500 miles on my N55, it was the older -943 pump, since I've had my new -933 pump, I have had no problems at all even though the car has been driven very hard since (I am at 5900 miles now).

Does this mean that the problem is fixed? Absolutely not, only time can answer this question. When I can say that I have 75K miles on the new pump with thousands of other owners, then I will know the problem is fixed.

Would this issue prevent me from buying this great vehicle??

HARDLY, however I would definitely get the upgraded stereo next time!

low and behold, thanks to the newly designed Realoem.com site, it lists the 933 Remaf. pump as the HPFP in the N55 X5... And like I've stated before I'm starting to have HPFP failure type issues, along with shadow codes related to loss of pressure

http://www.realoem.com/bmw/showparts...55&hg=13&fg=15 (X5 n55 hpfp part)

and for those of you with N55 335 (e9x) you have the same pumps:
http://www.realoem.com/bmw/showparts...55&hg=13&fg=15

I am really looking forward to what BMW puts out as the 'fix all' pump Better not be the 933, because obviously, it's not the fix or an effective solution

[laughter95]

this HPFP issue is the reason that is holding me back from purchasing at 335i.

[alex86]

There`s nothing that can keep me away from getting my 2011 e92 335i. Until the fix, that`s what guarantee is for!

But it is, the 933 pump with new software is the FIX

LOL I was thinking the same thing. The fix is basically to replace the turbos, HPFP, the coil packs, the vanos solenoid, the injectors, the DME, the IBS sensor, etc.

The thing is, dealerships (with BMWNA fully backing them) are reluctant to apply the fix. It simply ties up their bay and costs too much.

It's a fun car to drive. If a person lowers their standard and accepts that the car is unreliable, it's kind of like saying, "What else you got?"

The first time the car dies for no reason, it's truly disappointing. The second, almost as bad. The third through sixth imho a person gets numb and actually laughs. It's not like TV with all the dramatics.

[HoustonGuy]

what a piece of shit our HPFPs are...did not realize it was an issue for the N55 too!

[TeddyBGame]

Hi Folks,
Just trying to get a sense if we expect the N55 (MY2011 335's) to have the same frequency of HPFP and injector issues as those N54-ers. I ask because this thread has been pretty quiet these last few months and I haven't seen too many posts from the N55 crowd. Maybe it’s still too early to tell.... Maybe a crystal ball is required....

BTW - I've read almost every post/thread/FAQ on the HPFP topic in this forum and Bimmerfest.com.

So....here are my summary/questions (slanted towards the N55):
a) Early 2011 N55 builds have experienced long cranks and similar symptoms as MY2007-2010. With these early builds had the older re-man'd pumps (part# ending w/ 933, 170 & 446).
b) The HPFP failure seems to be the symptom and the root cause is still unknown. Safe assumption?
c) Do we anticipate the N55/HPFP to have the same extended warranty to 100-120K miles? It's hard to tell as the N55 has only been on the road for the last 12 months. Crystal ball needed...
d) What can one expect to pay to replace the HPFP and a few injectors when out of warranty? I imagine we have some N54 owners who are out of warranty now.
(I’ve read that the pump costs $700 and you can expect 5 hours of labor – so $1200)

The reason why I ask is that I’m about to order a 335ix E92 for an Aug/Sept ED and plan to keep it for 8-10 years. I’m well aware of what it would cost to maintain these cars outside of warranty, but having to address the HPFP every 10-20K would be a real bummer...

Thanks folks!
-Ted

[ericlol]

I did a mad tons of research before I pull my trigger on the N55

According to research done on these forums and google, the frequency of HPFP failure of the N55 is only a fraction of what it is for the N54.

I would say, just do it now, and worry about maintenance 4 years later
