Hey, this has been puzzling me for awhile, but what is a HPFP and what is the problems I hear so often? I searched the internet and no one place can lead me to a straight answer. Also I am young and not exactly mechanically savvy haha. Please someone explain this to me before it bugs me to death!

HPFP stands for High Pressure Fuel Pump. They are installed on N54 engines on the LCI twin turbo 535i and 535xi cars from 2008 on. For some reason the pumps seem to have a high failure rate. The 135 and 335 cars are also affected with the same engine. In the US and Canada they remain under warranty for 10 years or 200,000km (Canada). Some people have had multiple replacements and most others have had none. To my knowledge there has never been a recall. Your 2006 should not be affected. No problems with mine.
Maybe others will chime in if I got it wrong.

Dude, I don't know how you could've missed it - its ALL OVER the internet. Was your computer online? j/k
Seriously, HPFP is a bit of a pain, if you're considering a car with the N54 engine, make sure you buy it with warranty. Even though the pump itself has an extension of it's warranty, it has been alleged before that the HPFP failure can lead to other failures, some could be really costly, as I'm sure you can guess.

Also, if you are having the HPFP replaced, try to make sure you're getting the "new" re-designed unit - not a factory-refurbished original design one. Although I'm 99% sure that 100% of all SA's will say you're getting the "new" one, no matter which one you'll be getting in actuality. Still, the re-designed version seems to have a very low rate of failure.
Yet another thing to remember about the N54 engine - and this has nothing to do with the HPFP, as far as I know - you have to make sure you don't overheat it. This is mostly only applicable if you track the car though.
PS almost forgot: with all the crap surrounding the N54's HPFP failures and so on, I still would get a car with this engine in a heartbeat. The only difference is, I wouldn't keep this car past the warranty/CPO, as I am doing with my 530Xi. N52 engine is not perfect either, but at least it doesn't have the expensive turbos and intercoolers for me to worry about.
