HPFP Warranty Extension
Is it possible? Could it be? BMW heard us and did the right thing. Just got a letter from BMW advising that they are aware of issues with the HPFP on 2009 Z4 and get this, they are extending the emissions warranty to cover the HPFP for 10 years or 120,000.00 miles. Its a Festivus miracle.
P.S., my HPFP died after 1,500 miles. |

Yes sir - I received my BMW Letter on this in the US mail yesterday!!! That still doesn't make me too happy as this problem could strand my wife. I guess there is just no making me happy - maybe they could fix the problem on future model years???

Does the HPFP problem exist for both the 3.0 and 3.5? I ask because when we received the letter yesterday, the letter specifically stated that the 3.0 had the problem but didn't say anything about the 3.5

the letter is sent to N54 engine owners, the N54 is a 3.0 liter engine with twin turbos.

Aren't they both 3.0 engines? The 35i is a twin turbo. The letter also says that it applies to my vehicle and I have a 35i, so, I will keep the letter in my file and pull it out if needed in the future.

correct, i was just trying to explain that the letter refers to the N54 and not the N52, since they're both 3.0 liter engines, hence deepseabluez's confusion.

It is only the TT engine. The normally aspirated 3.0 does not have a HPFP like the TT version. I received the letter yesterday for the 09 335i that I traded in. This was one of several factors I considered when deciding to get a S30i. I don't think BMW has fully resolved this issue and expect to hear about more HPFPs failing as time goes on. This is a real shame. It's not a big deal as they are, of course, being replaced under warranty. But if you are in the middle of the Everglades or Death Valley and it fails it can be rather irritating. Good luck to all of you with the TT engine. I think the failure rate is rather low but if it happens to you it really is a bummer. Some think it is related to the fuel in the US, others say no way it is a manufacturing defect with the pump. Not sure BMW will ever tell us what it is or perhaps they don't know. I do know it is costing them a pretty penny to keep replacing these pumps. I know several 3 series owners that are on their 3rd or 4th pump. This is pathetic.

Since it appears that there are folks here who have experienced the HPFP problem, would y'all mind describing the symptoms for us and if there was any warning before it crapped out?
I too don't want to be stranded somewhere if I could have had the thing fixed when it started acting up. Cheers |

Not first hand experience buit based on reading numerous posts from those that have experienced failure, it usually starts with longer cranking times, followed by stumbling and a check engine light with the engine going into "LIMP" mode. This will limit you to a speed of about 25 mph. Complete failure will result in the engine failing to run.

Read from some of the Bimmer forum posts that you may also get high pitch whining noise while cruising between 40-70mph especially after gear shifts.
At low revs, it get less alot less responsive and the need to step on the pedal alot more to get the car moving. Understand there are 2 HPFP. The rear one is the most problematic. Will be good if some of the folks who experienced a faulty HPFP shared their side of the story. |

Surprisingly these fail at relatively low mileage. Normally, a fuel pump will last anywhere from 75,000 to 120,000 miles. BMW's N54 HPFP has been known to fail within 2000 miles for new cars. This is unique to BMW as other manufactures are using HPFP and not experienced this problem. Although some speculate that it's a fuel additive related problem, logically that is highly unlikely. 1) As noted there is a fuel pump in the tank that uses the same fuel but they don't fail at anywhere near the same rate. 2) Fuel additives are not new but these pumps have been around a while, so making resistant seals would have been worked out long ago, 3) The same company makes other HPFS for BMW, and other manufactures, that aren't failing at the same rate. IMHO, it's design flaw that has something to do with how the pump itself is mounted on the N54 engine. The BMW X6 4.4 L v8 has Direct injection and uses a HPFP but isn't experiencing the same failure rate. Last edited by teagueAMX; 02-24-2010 at 08:25 AM.. |

MY HPFP failed around 1,500 miles. Symptoms included long crank times (3 to 5 seconds) and then finally, check engine light. I did not experience a total failure. I was able to drive the vehicle normally to the dealer. It took them 2 days to fix the HPFP citing that they needed authorization from BMW (WTF)? So, in my case, there was a diagnostic code generated. Have 5,500 miles now and all seems okay so far.

I have a 2009. My hpfp failed after 1,500 miles. Symptoms were long crank times and then check engine light. HPFP I believe is in the engine compartment. I think the letter said that the warranty extension applies only to 2008 and 2009 models. I assume everyone who has a 2009 35i would get the letter and it would not be contingent on a prior failure. In the letter they cite a very low failure rate but in the interest of customer service....blah blah...they are extending the warranty. Clearly the failure rate is something more than "very low" or they wouldn't be doing this.

My sense is this BMW's way of saying we've dealt with this problem until they phase out the n54, the high tek engine of the year award winner. Given that BMW has already issued the extended warranty to n54 3 series owners, IHO they will issue it to 2010 and 2011 Z4 owners as well.
