my car is an 03/08 build. original pump as far as i know.

got a call saying they replaced one injector, all the seals, new HPFP and update in the CAS module.

not sure why other users are just getting software updates. perhaps they perform a pressure test and their pump passed? but the tsb seems to say they should be replaced either way

thats what i originally thought. but after taking a closer look at the tsb's, the dealer has to scan the key or dcsnet, and if the response doesn't indicate a new hpfp they don't change it. I guess I can ask them to run pressure tests on my original pump and if it fails get it replaced that way. Than you question even more if bmw has really found the problem, or if the recall is just a publicity stunt in response to the publicized problem.

Had my 'recall' done yesterday. All they did was update the software. SI 13 09 10. My SA told me that was all my car called for. Also asked about the injector recall Si B 13 14 10 and he said I was not affected. Isn't a recall designed to fix a common problem before it happens?? They know the fuel pumps and injectors are garbage yet, for me, they are still waiting until they fail. Something seem not quite right there??? (original pump, 33k miles, June 07 build.)

I am sorry. Isnt BMW's slogan the ultimate driving machine and the cars are designed for performance? If they had put the fine print on the contract, " high RPM or press gas pedal to the floor will void the warranty" then I would certainly understand this argument which we all know no manufacture will put this claim in the contract.

^ So Tru ^

I tell them like it is, I punched it and this and this happened, now please fix it.

Hell I dont water it down. When I leave out the dealer ship I make it known at the stop light if its fixed or not.

hi guys,

i missed this whole talk about the HPFP before i purchased my 2007 335i in August 2010. Silly me for not doing research. Just yesterday i received the recall notice from BMW and have made my service appointment.

It sounds to me like BMW will "check" for possible issues and if there are no problems to begin with, they will not replace anything. Sounds fair. But what happens if i get the failure at a later time? I don't want to be burned with a big repair invoice. I saw some articles that BMW has extended warranty on HPFP up to 10years or 120,000miles but the recall notice does not state any of that.

Autoblog link to BMW class-action lawsuit

What should I do in my current situation? It seems the problem is prevalent so I would like to avoid any issues down the road by getting the dealership to replace the HPFP anyway, even if there is no issue with it. Is that even possible? Sorry for asking such a silly question.

So far, i have not witnessed a noticeable lag or extended crank times. But, as with any BMW owner, I am concerned and I would like to avoid any major bill if at all possible.


Thanks

As I read the injector recall notice, it only applies to "the N54 engine produced from 04/02/2007 through 10/31/2008". So folks may be having unrealistic expectations on any attention to their injectors. As to all the other variation in stuff done or not done to individual cars, I (and maybe some BMW service departments?) do not have a clue. It's a sad day when you have to bring in your own copy of the TSB.....

Ok folks,

I just received my car back from the dealer. Here is my current experience thus far:

* Dealer installed ISTA 2.40.2 - Programmed and encoded complete vehicle as per recall
* Performed vehicle test, checked fault memory, test low pressure sensor
* Replaced HPFP as per recall. Used part number 13-51-7-613-933 This is not the latest!
* Replaced 4 fuel injectors with part number 13-53-7-585-261
* Replaced 4 decoupling elements part number 13-53-7-564-751

* Car drives VERY VERY smooth.
* Car starts up immediately, as it did previously.
* Car idles at 700 rpms! This is not a fluke. This is on a fully warmed up engine after 20 miles of driving.

I suspect they raise the idle to 700 rpms in order to keep the HPFP from starving for fuel. Again, this is just a guess. Previously my car would idle at 550 rpms with fully warmed up engine!

Discuss.

mine still idles at 600, even after software update + new hpfp

Sorry, but no - read the 5th sentence in the injector recall notice. It calls out only that specific date interval. Here's the paste from the recall notice:
"the N54 engine produced from 04/02/2007 through 10/31/2008".

What's probably stupid about this is that it's probably not the pumps themselves that are the problem. Something else is causing it and they will continue to fail. And BMW has no idea what that problem is. Why else would there be so many multiple failures on the same car? And this has happened on the 933's.

[waterp7]

Why are the 07-08 N54 engines only included in the fuel injector recall if all N54s share the same parts? Were there more problems with cars from this production year?

Ah, injectors. Yeah, I missed that.
Bummer, HPFP and injectors....

Me and my SA have long speculated the pump is the scapegoat for somethign else - known or unknown (but probably unknown) or at the very least, a downstream failure of something else.

People are too high strung about remanned pumps. Tons of automotive parts are remanned. It doesn't mean you're getting a used part, it just means the recycled the parts that don't wear out.

My car idles all over the place. sometimes 550. sometimes 700. sometimes higher. all warm.

I'm on my second fuel pump, I've been flashed six ways to sunday (as if that would fix a fuel pump issue?), and I've had 3 coil packs replaced, and all my plugs. BMW also had my car hooked up to diagnostics for two weeks with Germany, where every day Germany issued a battery of tests, and then the data went back, and then more tests, etc. The last day included an inspection of my valve train, which was completely gummed up like nothing my SA had ever seen. they cleaned it out, and the car ran like brand new (didn't even realize how much power had been left on the table as the gum up happened so slow).

Still screwy/stumbling idle. Long cranks havne't resurfaced yet (last serviced on this crap about 9 months ago), so I may be in the clear. Who knows.

But I'd bet dollars to donuts chasing the HPFP as the culprit is a phantom, or at least a downstream issue of the real problem.

[Tag]

So if it's not the HPFP what else could it be? I mean you have the fuel tank, LPFP, fuel lines, HPFP and then the injectors. Coil packs and plugs are part of combustion but not part of the fuel delivery. How can it be so difficult to figure out what it is? Am I missing something? I just don't get it. Some have asked if it has to do with all the heat. Either way BMW's QA sucks, that's for sure.

I have 49k on my car with no current issues (knock on wood) and am not sure replacing my "good" pump with a potentially faulty pump is a good idea. What do you think?

Mine just broke at 52k miles. Get it done. I put mine off thinking it wouldnt happen and I was "stranded" in limp mode.

Also the dealer had my car 7 days and couldnt figure out how to do the software update.

Edit: There were also 2 other people in the dealership at the same time for HPFP issues.

[F85_RN]

I have 09 335i got about 5k miles, have not had any problems but i stopped by at the dealership to ask a SA if there's any recall for my car. He scanned my VIN and told me there's software update but nothing else. I asked him how about HPFP, injectors, etc, he said nop......so i guess i'll see what happen...i've been hearing from alot of people where they lost hp after the new update....hopefully not...

I had my HPFP replaced this week due to the recall on my 2009 335i.

Unbelievable that one dealer would do your's but another says different...that would definately be my luck.

As far as the core problem not being the HPFP, who knows what it is. But when you keep getting pump failures over and over on the same car, shouldn't that dictate that something else is causing it to fail? And if the answer is no, then that's almost more scary. Cause that means that they can't design/redisign/manufacture/re-man a damn HPFP right.

I just can't believe that it would cost more money for them to take an N54 motor and figure out what the problem is once and for all instead of all these replacements.

BMW should just run the motor on an engine dyno non stop until the hpfp fails. Afterwards, tear down the internals and examine the parts.
