Back-to-back HPFP failures...

Rando · 04-20-2009, 08:30 AM

Thought I should share this since it's sort of alarming... My 335i had its first HPFP failure after 30,000 miles... that was just about a month ago.

And now, just about 1,000 miles later, it's about to happen again.

First symptom: 1st gear doesn't have its normal bite (in ordinary non-limp mode driving, with no warning lights)

Then an engine malfunction that resets when you restart the car.

Then long cranks...

Then permanent engine malfunction with reduced power.

Also it seems that medium-ish driving (like 40 mile trips) really taxes the HPFP once the failure process starts. Sort of pathetic if you think about it. The 300 HP 335i is scared of a hot day and a 40 mile trip!

I had some long cranks yesterday after the car was sitting for a while. However, no long crank this morning. I'll be keeping my fingers crossed.

sad... purchasing a $40-50k car having this never ending problem. Cmon BMW engineers! Do your homework!

I'm sure they did. I'm sure it included an extensive CBA and determined rebuilding and reselling existing pumps was more cost effective.

sad but it seems like that might be true.

diablo2112 · 04-20-2009, 01:00 PM

No doubt, and the CBA looked only at the "costs" to BMW, not the hassle, lost time, and generally poorly-treated customer in this whole affair. I adore the 335, finest car I've owned in this class, but I'll go back to Lexus if this is still hanging over the N54 in a year or two.

Hope they figure out this problem soon!! Its terrible every morning praying that you wont have a long crank in a $50,000 car. What are the odd they will figure out the problem rather then never figuring it out and just keep replacing the pumps?

If the rumors are true, BMW is looking at an electrical pump (this one's cam-driven) for the updated engine. In that case, it would make no sense to reengineer the existing one.

...for the record I'm on my 3rd HPFP as well. Does anyone know with certanty that replacements are "rebuilds" and not an upgraded HPFP? Can we tell by part number?

There are "new" part numbers that have also been subject to early failure. One poster also had "RMFD" pump installed when he got his replaced.

DenverJayhawk · 04-21-2009, 09:41 AM

Not having a 335, my opinion is pretty worthless here. But IMO, I'm skeptical that fuel quality is the issue. I've traveled to several countries in different contintents (europe, asia, etc) and judging from the appearance of these filling stations, I would doubt their fuel is superior to even the shadiest pumping locations in the US.

Anyone ever see a gas station in central Mexico? If fuel quality is the issue, I would think BMW would have trouble selling their cars in countries like these.

Further, if fuel is the cause, does anyone know if the 535 and X5 have the same frequency of HPFP issues?

I believe all the N54's at this point are seeing this issue. Keep in mind, though, the 335 and 135 are likely driven completely differently than the others in general. More stress on the pump makes it more prone to fail.

Frosty · 04-21-2009, 10:39 AM

... more stress on pump really (beating the deceased horse) should not be an issue in my opinion..

that said, as long as they keep replacing dead / low performing ones at their cost then we are eve... BMW and I LOL

That is of course until the day comes when you are off to something very important and the car dies in the middle of the road.

I've had one of the new ones fail, and the RMFD'd one mentioned above was also the new part number.
