This might be a no brainer or not but most HPFP failures seem to be in the US. I've also read that although ethanol has a better octane rating than regular gas, it's corrosive to fuel lines and ultimately the HPFP. I would had thought that Europe being an overall "greener" place would use more biofuels than the U.S. but that's a sidebar note. The vehicle was obviously developed in Germany but I guess BMW didn't take into account the amount of ethanol that is present in U.S. fuel?

read it, thanks for the link

I have seen issues where the dealer will refuse the hpfp replacement under warranty if the ethanol levels are above 10%, there was an issue where the dealership told the owner that there was 18% ethanol in the gas..

plus the whole "ethanol is greener" you eluded to (OP, about Euro) isn't true anyway. The amount of oil/petro used to process the corn into fuel kinda offsets the green'ness. Not to mention it is causing price inflation on corn (etc.) and other issues related to supply and demand. Bottom line, the ethanol movement is just government scam/BS fueled by the bleeding heart liberals who are responsible for our stimulous package which has government housing getting retrofitted with doorbells? I must have missed something

I don't think it has anything to do with DI. Maybe VW built a better/more robust pump able to handle corrosion agents better? Their products are further reaching than BMW's.

bio fuels are a relatively new technology. it still needs time to be refined. did you realize that gasoline was a waste product when obtaining kerosene in the early days. let's not even get into gas flaring that's still going on right now.

the only reason why there's a fluctuation in corn prices is because there's a strategic corn surplus (in case there's a bad harvest) that is being tapped. before ethanol most of that corn was stored and rotted anyways, but because it was stored and could be pointed at no one cared. once logistics (if ever) are worked on and ethanol is produced from grasses/cellulose(sp?) material (a proven carbon lowering method) things will settle. So your plan is not to seek other methods of energy? Yeah, let's stay dependent on foreign oil and be at the mercy of whatever yahoo has the biggest gun and controls the oil fields.

the stimulus package isn't perfect man, I'll be the first to admit that. it's meant to prime the economy, that's its job. let's give people a one time tax cut so they can pay one of their overdue bills and pretend their house won't be taken away the next.

Actually I pay my bills on time and I am not swamped down with credit card debt... if I can't afford to buy something in cash then I wait until I can. I actually SPENT my stimulous money last year on SS brake lines, new front pads, front slotted rotors, and some Motul RBF600 FYI. But that was selfish of me I guess, I should have given it away to somebody standing in line to cash their welfare check since the food stamps haven't arrived in the mail yet

BMW isn't the only one adversely affected. Lexus had a recall on 2006-2008 cars because of these ethanol issues corroding their fuel systems.

Reminds me of the old E34 issues with the nikasil block problems on the 540s and 530s back in the early 90s.

Knock on wood, I haven't had any HPFP issues at all (5/07) build. I've been using Toptier gas like Shell and Texaco, but there's times where there are no options.

i read about it, lucky for them it was just the fuel lines for them.

you got me there boss. i was under the impression that ethanol would have similar effects in non DI vehicles that didn't take ethanol into account, but following that logic there would be a lot more vehicles f-ed up.
