I think my 933 is failing, car was seeming rough, then "check engine soon" light came on and was extremely rough with reduced power, but no limp mode. Light went out a few miles later, seemed ok, but it's back at the dealer now.
Luckily they had a Z4 s drive 35i as a loaner, usually just get a bare bones 328i. |

I called the dealer today they told me part number ending in 446 was installed on my car. Some of my friends suggested putting a couple of gallons of 100 octane every so often to help with carbon buildup and lower the methanol contamination in the fuel system. Anyone here of this does it work?

Also, at my local track, you can indeed buy 100 octane fuel without ethanol (or so they claim.) Actually, IIRC, it was sold as 99 octane, and yes it was unleaded of course. Two different fuels ~may indeed~ have different ethanol content but the same octane number, but adding ethanol does increase RON and thus (R+M)/2 must be higher too: http://www.tpub.com/content/altfuels...8/47880249.htm

Actually I am just the opposite; I would like to see the data "proving" it is ethanol related rather than not ethanol related. It would be so kind if the data was shared by BMW NA. Got to give props to Toyota for allowing a deep investigation via two third party panels to prove their point. That shows a deep confidence in their product with an open door policy. Has anything like that happened yet for this issue?

Me too!
No recall letter and at 52,700 the HPFP Failed and as luck would have it, it failed when my wife took the car for the first time be herself. All other goodwill impressions just went down the tubes and trust now has to be re-built. Dealer seems to understand.....I have an appt for Saturday morning. I feel fortunate to be armed with all the info found on these pages so I know what right will look like when I see it! Thanks all! |

I've found that after the 3rd replacement the dealer knows you and your car and its kind of like going to the dentist to get your teethe cleaned:
Dealer: "Hey, just back for the usual?" Me: "yep, throw it in and I'll be back by 5pm to enjoy my new fuel pump for a few more months" |

Sorry to hear. Do you use ethanol-free fuel? Please correct me if I'm wrong, but the EU (EN 228) specifies that fuels may have 5% ethanol. Is it any different in Italy? Cheers.

I read these posts every day and dread the day I actually have a problem because I know once I take my car in the first time I am screwed forever. I'm close to 16,000 miles with no problems on a May 07 build and I really don't want the dealer to touch anything, software, HPFP or anything. Why the hell have I never received a letter? I wonder what percentage of the cars have been effected. The craziest thing is there are so many manufacturers with so many turbo charged cars that do not have this problem so why can't BMW figure it out. It must be something to do with the basic design of the engine that would cost them literally hundreds of millions of dollars to fix that is making them just put bandaids on.

BMW wont send those letters because this is not a safety issue it is a emissions recall. Sounds much better that way,less alraming and less ....bad for publicity(sales)
Laughing at the dentist comparison, thats how it was with my dealership and the shop foreman

Just when I say no other manufacturers have this problem todays paper says the US Gov't is investigating 100,000 2009 and 2010 VW TDI diesels for HPFP failurers. The good news it can't be an Ethanol issue. Soprry I don't have a link it was in todays Columbia, SC newspaper so there must be something on the web about it. I think it also said emissions but said cars have stalled and accidents have happened (sounds familiiar). It also listed the Audi A3.

Sorry to hear about the untimely place for a malfunction.
Glad all turned out ok with the family. The ONLY bright thought is at least it happened in Italy where train work strikes can and do happen on a schedule. Be safe. |

Picked-up my car from the dealer.....it was (as suspected) the HPFP, but my car was only in need of a reprogramming.
HFPD checked out fine.....allegedly! SA "reassured" me that BMW will make it right if the pump fails. The good news is that the car really does run better after the reprogram. At this point I am a happy camper. |

I was looking around ebay for a csar and saw a buyback for sale. This is supposedlyu what BMW told the dealership that has the car:
Note: This 2008 BMW 335i Sport Coupe was reacquired from its original owner by BMW North America due to downtime associated with a warranty repair. Problem(s) reported by original owner: "Reduced power and check engine light on." Repairs made, if any to correct reported problem(s): "Replaced vacuum tank." The vehicle has been thoroughly inspected and the non-conformity listed above have been corrected - Repairs made by BMW! Important Warranty Notice from BMW of North America: BMW has extended the warranty of the High Pressure Injection Pump (HDP) from 4 years or 50,000 miles to 10 years or 120,000 miles whichever comes first. Details are contained in SIB B13 03 09. I do not think I have ever heard of a buyback for a vacuum tank. The person that bought my car was looking at a different 335 and the dealer wasnt even going to tell him it was a buyback. He found out from his loan company which told him they would not touch that car with a loan because of the title. I am carless, I have no wheels

The question is : On the HDPF (mechanical pump) the problem is the electronic Valve ? The position of HDPF (Near the engine)
