Anyone else worried about the fuel pump failures???
I was hoping that by now BMW would have solved the high pressure fuel pump problem, but the failures seem to keep popping up on E90post. I sure hope this is resolved before the 1er comes to the States. I know the 1er will be one helluva performance value, but I can't see myself buying a vehicle knowing how high the chances are for it breaking down.

Has there been any reported issues with the revised replacement pumps?
I don't recall hearing of any. This engine is going to be BMWs bread & butter for the foreseeable future. You can count on them figuring out the fuel pump problem. (& the over heating).

I've just noticed several threads on e90post where people are experiencing symptoms of HPFP failure with their replacement pumps and needing their cars serviced, again...
Here's one of several examples: http://www.e90post.com/forums/showthread.php?t=77664 'Los |

and even ethanol mixtures who've experienced trouble with the replacement pump. C'mon- BMW goes out of its way (decal on interior of fuel-tank lid) to warn all BMW drivers not to use low octane...and then these idiots who've shelled out 40k+ on a 335 pour ethanol mixtures and cheapo gas in the tank. Unbelievable. Legally, when this is done the owner/leasee has broken the contract- tho I've only heard of BMW taking the car back (a 335) once from a friend of mine who works in a New Jersey dealership. So, can we stop with the scares? |

i plead ignorance. perhaps someone can help me understand. i was under the impression that ethanol additives to gasoline raised the octane of the fuel mixture.
if that's the case, and people driving performance cars need higher octane gas, then why do people look down on using ethanol? does it damage fuel line components in other ways? thanks for any info! p.s. from that link above even Top Tier gas is required to have a minimum of 8% ethanol. |

Ethanol is a fuel component that displaces some petrolium based gasoline in the mix. It actually contains less energy per volume than petrolium gasoline. Quote:

thanks for the explanation but this confuses me a little then
"The standard "blending octane value" for ethanol is about 113. Normally one litre of ethanol blended with 9 litres of petro-gas raises the octane of the 10-litre blend to the next grade level. For instance after blending 9 litres of petro-gas with one litre of ethanol, Regular Unleaded (87 octane) becomes Unleaded Plus (89-90 octane) and Unleaded Plus becomes Premium (91+ octane)." http://www.gov.mb.ca/est/energy/ethanol/ethanolfaq.html anyway it's not that important to me ... i just just curious. thanks! |

Here's another one. Freakin' ridiculous. As much as I would like to own a 135 I'm having some serious doubts about the reliability of these pumps. I sure hope BMW does something FAST!

2/ also, i understand that the new pump is a bosch, and the older pumps were the siemens. i am getting my 2008 335 in about 45 days, i am just hoping i will have a new BOSCH HPFP ! my guess is that: 1/ BMW still has the older siemens pumps in stock maybe they are still using these siemens pumps as replacement pumps 2/ I AM HOPING that all new cars with N54 motors have the new BOSH pump. anyone out there no for sure of any of my speculations? |
