Unhappy Dreaded Fuel Pump - Please fill me in!

I have a 2008 BMW 335i conv... Production Date July 2008 and was delivered to me in August..

After having my car for about 2 - 3 months, the car started having long crank times and on different occassions it would take mutiple tries to get the car to start - they replaced the fuel pressure pump, noting that they had some problems with the previously installed one.

Just about 2 weeks ago (at about 8,700 miles) - the car started doing the same thing... After BMW Service Center had the car for 3 days my SA apologized and told me that he was a little embarrassed to note that it seems that they replaced my fuel pressure pump, with yet another faulty one.. (!!?)

So now it has been replaced for a 2nd time and I "should be good to go".

I have been kind of skimming over the previous posts and noticed that this has been an ongoing problem. Should I be worried?? And why are they not removing these faulty parts from their inventory and restocking?

This is my 3rd vehicle (1st Bimmer) and I have never experienced problems like this. Very disappointing, especially since this was a huge "upgrade" for me...

Very sad to hear but as you are aware, you are not alone.

There is not much confidence even with recent factory builds ('09s) that there is a clear correction to the problem.

Good luck on your third.

Thanks for the reply..!

I'm not really well versed in the "mechanic" world.... but can this have any effect on other components?

My understanding that the high pressure fuel pump (found in-line within the engine compartment, it's in addition the traditional in-tank pump) simply is unable to deliver fuel to the cylinders at the required pressure. The engine is then starved for fuel and will not function effectively or at all. Thus long cranks and or limp mode running.

The lack of fuel should not harm your engine as long as the occurrence not take place when you & your car are in transit and at risk.

Good luck.

I can only assume both were at zero cost.

If it makes you feel any better, I had to have my '08 HPFP replaced at about 4k miles

HPFP warranty is now 10 years, so free HPFPs for the next ten years for us all

I would argue there is an inherent design flaw in the E90's (335's) that is causing excessive fuel pump failures.

Afterall, would we not see the same issue in the 535 and X6 3.5 if it were a part issue?

Heat, vibration, pressure, etc. Something is not right. I suspect the pumps are fine, it is how they are used in the 335 that may be different than other models. Otherwise, I think BMW would of had the problem fixed by now.

I've read other posts that also state there is a ten-year warranty, but where do you get that from? Is it on the BMW website or an official press release?

Yes this 10 year 120kM warranty seems like a rumor to me...

The 535's have the same HPFP issue, take a look at the E60 forum here.

You can call BMW NA to verify.
If you go in for a service or something, they should give you updated warranty info as well.

ED or Mil Sales

Out of curiosity, anyone with an ED or Mil sales purchase having this problem? I can't imagine it makes a difference if all the E90s are made in Germany but was just curious. b I assume this isn't just limited to BMW NA

The fuel pumps in the 335i are under spec'd for what they need to do for the vehicle and the quality control from Siemens and Bosch have not been great. Some will say it's the ethanol, but that's crap. BMW obviously feels it's cheaper to replace under warranty than to R&D a pump that actually works and lasts.
