my car just left on a flatbed to the dealer a few hours ago. i have nearly 51k miles and it has all the symptoms of hpfp failure. Long crank, SES light, reduced power due to engine malfunction, rough idle, nearly stalled several times, etc...

Does anybody hear a slight pumping or primering sound when you insert your key but not pushed start?

I had my plugs replaced about 3k miles ago and it seems like before that I used to hear that primering sound or something just before I pushed the start button.

Second time in the last two weeks; the car cuts power and goes into limp mode under hard cornering.

Both times i was cornering hard from a dead stop. HPFP?

I got rid of my E46 M3 because I was starting to not trust it on long work trips...now I don't feel I can trust this MOFO to go through the mountains or on a trip longer than four hours!!

Yep! it was the HPFP, just got home with my car, running like normal, i think. The dealer experience kinda sucked though.

I hear the sound you describe on both 335i and 330xi. I've assumed the sound was made by the fuel delivery devices. When I allow the sound to run its course to prime the car, the engine starts without hesitation. When I push the start button while the sound is still audible, the starter has to do a bit more work before the engine starts running.

Sorry about your car, good luck repairing it.

We are probably on the high end of the mileage people had on their cars when there pumps went out, my pump was replaced yesterday, 51k miles.

I asked the SA by phone if they were going to use the so-called new improved HPFP and he told me that they would use the "latest and greatest". (his term, not mine) Well, when I got the invoice it had the old part number ending in 881 and he was too busy for me to discuss it, so I just left.

Just another typical dealer experience where I leave slightly to very frustrated.

- Your car has long crank (it will take longer than usual to start the car) repeatedly and/or
- You're driving on the freeway and the 1/2 engine light (malfunction engine light) comes on. You could still drive the car home. Sometimes, the 1/2 engine light disappear the next day but you do need to take it in. If the dealership is nice enough, they will test and depend on the result, they will go ahead and replace the HPFP for you. Other dealerships won't touch it if they said "No HPFP code was found". YMMV.

The 1/2 engine light could come on for different reasons: injectors, spark plugs, coilpacks, whatever else but if you have a combination of 1/2 engine light and long crank, it is your HPFP. At least that's what happened to mine.

The 1/2 power indication can be lit by a myriad of engine systems. Everything from HPFP (and other fuel related issues), to VANOS solenoids, to a kink in a Turbo vacuum line. It is not the best indication of HPFP failure.

The 1/2 light will be reset by shutting off the motor. If the the problem still exists, then 1/2 indication will relight within a few moments or when the problem reappears.

Service Engine Soon (SES) almost always accompanies an HPFP failure. (Out of 4 pumps - only one time the SES didn't light on me. In that case, the pump was working, the problem was that it was leaking fuel) A solid HPFP failure has the ECU bypass the pump and shuting off the turbos. The fuel controller instead sends the fuel directly to the injectors. The reason why the engine is shaking/running rough - only low pressure fuel is supplying the cylinders.

2. How many miles on the car when HPFP failure could happen?

I've seen 500 miles, 1,200 miles, 62 thousand miles, who knows. I'm not a psychic teller.

3. Which MY HPFP has failed the most?

Based on reading from this fantastic forum, 07 and 09 MY. Yes, someone will say I have a 07 and still on original pump so what gives? Who knows! As of 12/25/09, MY 2010 users also reported HPFP failures.

4. Which brand of gas I should stick with?

There is no telling. People who had Shell only or Chevron only, HPFPs still fail.

5. Is there a permanent fix for this?

There is a well known shop who's working on a better pump. There is no telling when this pump will be available. Search is your friend. When it comes out will it work better? Who knows!

6. Is tuning the cause of HPFP failure?

There were threads swear that HPFP failure is not tuned related as there are folks who did not have tunes, HPFP still failed. You make the call.

7. Could HPFP failures continue after 3-4 replacements?

Yes.

8. With the HPFP failure like this why you guys/gals still have the car?

- BMW extends the warranty to 120k miles. The replacement takes only few hours and you're good to go. As of 12/21, MY 09 and 2010 users have not received letters to state the same extended warranty for 07 and 08 MY users.

- Can't afford the lost to trade in for a different car plus everything else is more expensive and who knows the other brands don't have issues?

- Can't find another the car that could drive/handling this good and still is affordable with the luxury for the Jones.

-under California (and possibly other states), if the HPFP is replaced 3 times under original car warranty, your car may qualify for a "buyback" under the California Lemon Law. Google search gives details.

As of January 2010, 09 MY will have the same 120k miles warranty for HPFP. See http://www.e90post.com/forums/showpo...9&postcount=96

9. OK sounds good, if I decide to keep the car, is there anything I could do to prevent it from happenning?

Not really. But if you own a high 40k's or 50k's car, you should get a BT scanner for a few hundreds. Scan your car to see if it generates any HPFP code. However, mine did not generate any HPFP code (long crank, 1/2 egnine light came on) but the dealership replaced it and i'm back on the road.

10. As of November 2009, BMW has given another try to improve the high pressure fuel pump in the N54 engine. The last/old part number for the HPFP ends in 881.

The new HPFP part number is said to end in 943.

There is no data and no other information as to what this pump fixes or doesn't fix.

Updated: The new pump that ends with 943 is no longer made by Bosch. It is made by Continental. As of January 22nd 2010, dealership will still have to use all the old pumps that end with 881 before 943 could be used. There is no telling if 943 will fix the issue for good as it was released in November 2009. You could also order the new pump from Tischer.

From historical data (getting from insider ), the fuel pump, that was made by Bosch, normally goes out after 40,000km. Bosch provides pumps for both, at least, BMW and Mercedes. We will have to see if Continental pump will have any improvement.

There might be possibly a second recall as both Bosch & Continental are about to pay both Mercedes and BMW for the failing pumps. Cars with Novemember 2010 build dates should have the new pumps that end with 943. It sounds like, no real proof/evidence, 943 will be the fix as several testings were done.

11."What should I do if I experience any of the symptoms you described in Question #1?"

Answer: don't waste time posting about it or talking about it -- take it to the dealer ASAP to avoid a potentially dangerous situation.

12. Has anyone contacted NHTSA and what was the result?

Yes. NHTSA already has a case opened and they continue to monitor this issue.
http://www.e90post.com/forums/showth...=279731&page=2

13. Has anyone filed a lawsuit against BMW?

Yes. http://www.scribd.com/doc/17233560/Bmw-Law-Suit-Hpfp

Here is another one in California http://www.consumeraffairs.com/news0...12/ca_bmw.html

Y'all feel free to chime in/update/corrections, etc.

pm for nice guy!Thanks for doing this

So i just had my SES light come after a long crank. The engine started shaking and i restarted the car. SES light goes away but i still take it to the dealer and they check it out and say it was because i had low fuel?? Is that really possible or could they have changed my HPFP without telling me because they knew i would lemon it since its the 3rd time in about 5 months? Is there anyway of knowing if they really changed my pump?

Another one the dealers love to pull is to tell you that you bought some bad gasoline, and that they can also sell you some BMW fuel injector cleaner which will help. I tell them maybe i will just buy some Chevron cleaner next time I am at the Auto parts store, the SM says, "oh' this is different from that Chevron stuff". i buy a bottle and later i am pouring it in my tank and i notice the bottom of the bottle says Chevron Corporation. Same shit, but i paid more for buying it from the dealer. Some service managers are idiots!!:

08 HPFP victim here. 24k Miles

Dealership replaced HPFP and Low Pressure Sensor

New HPFP was not the new 943

Low fuel won't cause SES light and shaking. Bad fuel could certainly cause the engine to shake. I have mine low fuel all the times. How low did you let yours go?

I would take it to a different dealer next time if I were you.

2008 335i sedan, just started getting long cranks, will be taking it to the dealer this week. 22K miles.

[PUMPD]

Long cranks and rough idle. It is in the shop as we speak. Getting new HPFP with the new part # 943.

Well, it's good you're getting the new pump. We'll be able to start following soon, how those new pumps are doing...

[chromisdesigns]

Took my '08 in this morning for long cranks, and was told by the service writer that they got a memo from BMWNA last Friday, instructing dealers to scrap all the HPFP's with the old stock number, and to order and install ONLY the new part number pump!

Interesting...

[quattr0]

^ Indeed...anyone else knows a friendly SA/mechanic could confirm this? But then we will still have to wait and see how the new pump works. At least we know BMW is trying....

[minicrazy592]

Can someone post a copy of this memo?

[PUMPD]

New HPFP installed, car cranks right up, feels soooo goood. My Sa told me they shipped all the old HPFP back to BMW,and he has all new part #'s. Can the dealership update your ECU without telling you ??

[Longbow64]

Got a new HPFP today.

Stats:

08 335i
25K miles

Symptoms:
Long cranks
Sporatic Engine shuttering when accelerating that cleared by restarting the car
Finally randomly flagged the SES light after hitting 4000k rpm, engine shuttering followed
no Limp mode indicated (which was kind of weird compared to everyone else)
Fault Code 2FBF according to BMW Service Test

Fix:
Under warranty, dealer pointed out the extended warranty plan of 120,000 miles
No issues replacing HPFP under warranty even with Injen DCI installed.
13-51-7-592-881 HPFP fuel pump installed

[Longbow64]

Hopefully this one will last until BMW really fixes the problem

They should NOT still be installing those old pumps -- effective last week, BMWNA instructed dealers to send them all back, and only install the new part number.
