#48 of 51 BMW 335i: Fuel Pump by nickkappos

I don't know if this helps at all, but last week my 2008 335i had a "Engine Malfunction" warning, followed by the check engine light - the physical reaction was reduced engine power.
 
I took it to the shop and they said it was a bad fuel pump and said it was "covered under warranty." Now, my warranty has been up for over a year - so she may have meant it was covered under a recall? I'm not sure.

The 3.0 twin-turbo is pretty famous for having a high incidence of HPFP failures... I'm sure there is some sort of recall or extended warranty on them...

The turbo's have a high pressure pump. It's a known problem and they stood behind it with a long extended warranty. Ten years seems to stick, but that's very long so I could be mistaken. But that's the way it should work.

My fuel pump failed on my BMW. It was sitting in my driveway. It was towed to the mechanic. He replaced the fuel pump. It sat over night in his garage. It would not start. He replaced the fuel new fuel pump again. I drove it home. It would not start the next day. I towed it to the mechanic. He replaced the fuel pump a third time. It sat over night. It failed to start in the morning. At this point, after thoroughly checking the car, he cut open the original fuel pump. The impeller had swollen. He emptied the fuel tank, saving a sample of the fuel. He believed that the fuel had caused all of the fuel pumps to fail. I also live in the Hudson Valley, NY. The issue here is neither the age of the car nor the age of the fuel pumps. Even the make of the pump cannot be blamed because my mechanic used both BMW and non-BMW parts trying to repair this 2001 BMW 325xi. Something is seriously wrong and potentially dangerous if alcohol placed in fuel can essentially melt the part. It's both the fault of oil companies and the car makers. For what it is worth, in Westchester Co, a higher ethanol content is required during certain months of the year, higher than surrounding counties.
