AFAIK, there was no failure of -943 reported yet, neither here, nor on the Bimmerfest. Good luck.

[quote=quattr0;6401179]1. What are the possible symptoms of HPFP (High Pressure Fuel Pump) failure?

-under California (and possibly other states), if the HPFP is replaced 3 times under original car warranty, your car may qualify for a "buyback" under the California Lemon Law. Google search gives details.


Anyone know if this applies to leased vehicles? Can I terminate my lease if I had to replace 3 HPFPs?

I had my HPFP replaced at around 9k on my 335i and I would like to ask-- what would be the correct way to avoid something like this happening again? For example, certain gas brands, driving style, tightening the fuel cap etc... My apologies for the childish question, but I would like confirmation on what not to do. Or in other words... what could I do to induce a HPFP issue? Thanks!

Nobody knows! (except, perhaps, somebody at BMW but they aren't saying). Seriously, no root cause has been established, and it's not clear that it has ANYTHING to do with how you drive, what kind of gas you use, mods, etc., etc. It's a black hole.

Interesting, had the same symptoms and the same code (2FBF) and the car went to the dealer last week. They reprogrammed it but referenced SI B12 55 06, are you sure you didn't miscopy that number? They didn't change the fuel pump.
The long crank times went away, but the car still runs like crap. Going back next week.

Your question is not childish - all of us would like to know. It is as chromisdesigns says: none of us knows. Those who do know claim that there is a problem in only a small percentage of cars, but there are no hard data about the frequency of the failures and the reasons. Rest assured that it is not your driving style that's causing the problem - the 335i is a daily driver class car, which should be as reliable as most of them. It you want to learn about the fuel quality problem, you can search the forum, but it is likely that there never was any fuel problem. The fuel discussion started in 2007 when a few BMW dealerships allegedly at first refused to replace the failed HP pumps under warranty, claiming that the pumps were damaged by fuel that was not meeting the required specifications. If you want to look at hard data on fuel quality, they have been posted (http://www.bimmerfest.com/forums/sho...d.php?t=435606). Most members of the forum agree that for those using reputable brands, there is no correlation between the fuel brand and the HPFP problem.

Canada is different, don't know if BMW extended the HPFP warranty there, or not. Try calling the corporate office, the dealer may be blowing smoke. Or maybe not.

Other than that the N54 is a great engine, well when it's running properly.
Lol.. I guess i wound agree to all that..

What's interesting is that although there are claims that the % is very small, curiously there are 335's wholesaling for 19k, and SIB 12 55 06 is so detailed there's no way so many scenarios and FC's could have been documented from a small %. It takes experience to be able to put together such a SIB.

You are absolutely right, the existence of the SIB 12 55 06 and fluctuating pricing indicates that BMW knows more about the HP pumps than they are willing to admit outside of the SIB area - after all, they employ a large number of the most competent engineers in the world. IMO, the problem lays elsewhere - they fear consequence related to the scale of the problem. Any reputable engineering school will award an "F" to an undergraduate for using terms such as "small percentage" for anything that is measurable and has most likely been measured yielding numerical results. On the other hand, an undergraduate learning marketing will most certainly get an "A" for the same vague glad-talk. BMW knows, but will not admit that there might be a high pressure pump problem, unless they are forced to do so, since they fear that hard data may have an undesirable impact on sales. There is also a risk involved in explaining complex problems - people seldom care. By recent BMW statistics, 80 percent of BMW car owners were not even sure if their car were propelled by the front or the rear wheels. If this statistical data were correct, it means that people who can understand the simple principle of propulsion simply do not care about it. How many car owners would be interested in the reasons for the HPFP failure? Unfortunately for BMW, the data showing that people do not care also indicate that a majority of car owners perceive the car as an appliance, and in the long run will favor appliance makers capable of providing not only a reputable badge, but also reliability.

Didn't have time to read the entire thread as I'm at work and checking out an E90 325i after...this is only with the N54 correct? So the 325 doesn't have this issue as it is the N52?

Thanks, and I know...

If you read through the thread you will get a good idea of where the situation is at with the HPFP issue. But in any case if you do decide to get the car I would use this as leverage to knock the price down a bit.
