Not sure why you assume a re-man or exchange pump is going in the production cars. The -446 & -170 are the exchange pump part numbers. But I know what you mean, BMW claims the exchange pumps are the exact same design as what is installed on the line.

In my experience, the only pumps that lasted 10-20K were the -181. Those pumps are so last decade.

My original pump went 59K miles. (I miss that pump). A -943 that was put in March 2010 went 43K miles. Currently running a -170 with 8K miles on it. So far I've gone thru 6 or 7 pumps and BMW keeps paying for them - even this last one although I passed the 120K mile warranty last year.

Reckon I'll see if the -170 will last long enough to hit 200K next year.

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!

If a recall does happen it wll be uner warranty for 10 years or 100k miles. On a side note not many n55 problms. I have about 29k miles ad zero long cranks.

[TeddyBGame]

Thanks guys. That's what I'm thinking too.

[DeepD.Fast.Rider]

Its a lottery, less on n55. If it is to fail it will most prob in 12-15k miles if it hasnt already before 5k miles. Ive has 2 n54s both failed after 32k, only one needed complete set of injectors. N55 will be bit more reliable.

[tbracing]

So I have a question for all you N55 guys. I have a 2011 335i with 1,600 miles on her, I dont have long crancks or service engine light, but lately sometimes when I start the car either in the morning or after the car sits for a few hours the RPM will start at about 1200 then drop down normal but start hunting for a few seconds and then idle normal. Could this be a start to a pump failure or just shitty gas? I'm in Italy so bad gas is as common as hot women Next month Im going on a long road trip and would hate to breakdown or have the engine light finally come on due to the HPFP 800 miles away from home.

[shockin330i]

Eh my idle sometimes bounces around as well. I just came came from a 3000 mile road trip and all iss well.

[nkadisha]

I thought the idle RPM bouncing was normal...mine does it too

[magnumforc]

We have two new 535i GT's, a 2010 and a 2011. The 2010 seems to be fine and the 2011 has already exhibited some problems. Quit dead as a doornail one afternoon. Just quit. No dash light warning, no power, nothing. Press on the accelerator and nothing. Vehicle acted like we hit the brakes. Luckily we were on the Coast Highway and in light traffic and after stopping it did restart. Blamed it on fuel as I recently fueled up in a station where the tanks were being filled (Don't do that but the tanker was on the other side of the bulding and car wash) It didn't reoccur and we made several long trips with no problem.

Now a loud buzzing sound emanates from the vehicle when opening the doors and intermittently at other times too. Dealer says it's the VVT system and cleared two faults but other fault will not clear. Some say the noise is the HPFP priming, but it occurs pretty often and the tech says the problem with the VVT is being looked at by BMW. Nice. 70K of vehicle and another quagmire!

Incidentally....from the Bimmerfest forums, they are INSTALLING THE 933 PUMPS:

N55 HPFP (Fuel Pump) Failure
________________________________________
I have to unfortunately inform everyone that I own a 2011 335i with the n55 motor and I have just had my fuel pump fail. The car is only 2 months old and only has 1500 miles. As always, it started with longer cranks, then an unbelievably odd start where it idle surged, then dropped rpm's and I finally get the infamous half engine light. (see attachment!) I take it in and they read the code, yep; fuel pump failure! It is currently getting worked on and should have it back by next week. It is ridiculous that this problem hasn't been fixed after 4 years and a new engine! Just wanted to share...
The new pump I received is a -933 pump which they stated was the newest they had after receiving a new batch

[Wild Squid]

I just picked up my 2011 E92 335i a few days ago. Does anyone know if the N55 HPFP is covered under the recall warranty for the 7yrs 100K miles like the N54?

Get it checked by the dealer, threaten him with Compensation if it fails etc, speak to the manager, get it changed ASAP. They will change it in 1 day. The long crank itself is a good enuff indiaction its HPFP going. Also take the lawsuit printouts with you.

Also I would NEVER use Techron on it. Everytime I use Techron I get long cranks....

[vamosankit]

been there done that my 2011 335xi went down with 4000miles after getting it fixed everything seems ok im at 5000miles now

What's wrong with using Chevron gas? I know some people prefer Shell for a reason but I really don't see a difference in gas.

[Powderguy]

Sad to learn! I have 2500 miles with no issues. My wife is the BMW junkie so if there is a problem she will take it in for the fix. My 2007 X3 with the jerky tranny was going to be my last BMW too.

That's BMW for you. My Z3 had unending problems with the fuel gauge sender (tank would read full even when it was empty, or vice-versa). Had it replaced 3 times during the warranty period. The last time it was at the dealer's, I overheard another customer talking to her SA about the exact same problem; her 3-series had also had several fuel level sender replacements, and she was asking the SA what would happen when the sender failed after the car was out of warranty. His recommendation was that she buy an extended warranty! Clearly the SA had no expectation that BMW engineers would ever design a part that actually works for the life of the car.

The conclusion I came to is that BMWs are not designed for the long-term owner, but rather for the guy who leases the car for 4 years and turns it in before the warranty expires. So the correct strategy is to only keep the car as long as the warranty lasts, then trade up to a new one.

No problem here, 2011 335i

Hey buddy, I was talking about the fuel cleaner , not the fuel...the fuel I have no Idea. In UK we have Ron 95 as standars, and Ron 97 to 99 as the higher grade.

But that comes at a price. The resale value of the car after the warrantee expires must plummet (I haven't researched this but it makes sense). So you may avoid expensive repairs only to take a bath on the trade-in value.

No such thing as a free lunch.

After that many pumps why didn't you just "lemon" the car and have BMW buy it back?

[Bcube]

Lemon Law applies during original OEM warranty.

Besides, a HPFP replacement isn't that big of a deal to me. Dealer has always given me a loaner. I don't lose any work days.

[fun2drive]

I think you should be getting the latest pump which ends in p/n 466. My N54 never had problem one up to 36K miles when the dealer put a new pump and reprogramming in. I don't hear much about these pumps failing.
I do think in some cases BMW gets too complicated when simple is a more eligent solution. From what I understand Siemens was the first supplier and now Bosch is putting the 466 pumps out. As mentioned the manufactures uses a lot of OEM suppliers.

I have always had terrific success with my BMWs but then again I maintain them and follow Mike Miller's old school guide.

You can't do much about a failing pump since it seems to be a world problem. BMW is loosing a lot of money having to do these pumps so if anyone wants this problem solves it would be them.

Hope this new pump solves most of the problems...

Is it me or doesn't seem that this issue for the most part has been resolved? It's been months since I've seen numerous people having hpfp issues.
