Warning Light - "Engine Malfunction - Reduced Power" - 2009 335i Sedan
It is a nice saturday afternoon here in SoCal so I decided to wash my car. I wash it at my parents house who live about a mile away. I had just come back from the gym - car was fine. I get in to start the car again and I get "Engine Malfunction - Reduced Engine Power" warning. Turn the car off - start it again - warning goes away - car feels fine. Drive over to the parents, wash the car - everything seems good. Turn the car back on to go home and it takes it a second to turn on (cranking)...car starts...im about 1/2 way home and it gets SUPER shaky...light comes back on...
Is this the fuel pump problem showing up in the 09s? Anyone else have this in an 09? I called the dealer and they of course cannot look at the car till Monday. So at the moment I am super pissed. I do however have a nice clean, $50k car with less than 5k miles on it to sit in the garage for the weekend. Great. Last edited by RiversideE90; 03-07-2009 at 04:01 PM.. |

It's the fuel pump.

Aw crap, now I'm scared. I have an 09 335i with 4k miles on it sitting in the garage too. I was really hoping that the HPFP issue was resolved some way, some how. Please keep us posted with your progress.

my 09 335xi at 2800km started to shake and lose power on the hiway, couldnt get over 3000rpm in any gear. my kids were freaked out. i needed gas at the time, so we stopped at the next station. filled up, started the car, and it was fine, like nothing ever happened. none of the warning lights on the dash came on. its now 6 weeks later, and the car has about 4500km on it and the problem has never reoccurred. thought it was just a computer glitch that needed resetting. for you american guys, thata about 1750miles and 2800 miles.
hope it is not the begginning of fuel pump problems. |

I had one replaced, it's not hell anymore, they changed mine out in a few hours. It sucks but it's not that bad. It's a known issue and the dealers stock the HPFP, so they should be able to fix it same day. Mine went bad at like 500 miles, so you got farther than me, lol.

Pay closer attention. They have a slightly different tuned N54 in the 740i.

it's not really that bad anymore.
It was hell before because they didn't have 'em in stock and cars had to be in shop ~ 30 days. Now it's just a matter of 1 - 2 work days.

You should NEVER use 91. Might be part of the reason why your pump is failing at this point in time.

Yup, my HPFP seems to be at the end of its life too... at 29,800 miles. (I thought I was safe, since my car happened to be built out of BMW's "recall" date ranges.)
Definitely feels like EVERY car is going to have this problem at some point... One interesting observation though: the wastegate actuators were *just* replaced a week ago... and now the HPFP fails. Coincidence? Or are they related? The engine was definitely a little stonger and lag was a little lower after the fix, so maybe that puts more load on the HPFP? (Completely wild guess on that one.) Also, yes... it all started with a few engine malfunctions here and there ("Engine malfunction... reduced power" -- but NO "Service Engine Soon" light. Restarting cleared the code and restored the engine. [This was weeks/months ago -- maybe 3 times total.] Then the engine got weak after some longer (~1 hour) trips... just not pulling properly, definitely reduced torque and HP. Eventually the "Engine malfunction" message came also, but still no "Service Engine Soon" light. [This was a few days ago.] Then long cranks started... and the dreaded "Service Engine Soon" light came -- sometimes there were harsh engine vibrations, almost like one cylinder was not firing correctly. Sounded like a very old car. I am hoping there is one start left in it to take it to the dealer! [This was yesterday.] I hope this info helps people identify when their fuel pump is on a bad path... |

Just a quick update on my car...
Took it into the dealer this morning...problem is apparently the fuel pump and some cylinder misfiring and they are still working on diagnosing fault codes. And of course - I ask for a loaner car - "this dealer does not provide loaner cars." Time to call BMW Corporate I think. This is a $50k car with less than 5k miles on it and now I am having to borrow cars from family members? seriously? |

The dealer did offer to split the rental with me. But I do not feel I should have to be out any funds for this car - at this point.
Just called BMW Corporate...they said they can't force the dealer to give me a loaner, as the loaner car program is completely up to the dealers. This is crazy! Felt splitting the rental was reasonable, especially considering I did not buy the car there. Guess I will see what tomorrow holds....luckily I have family close by that does not need a car beyond getting to and from work - so I get to play taxi in exchange for use of a car. Exactly why I spent $50k on a BMW! |

So it's Purgatory then. It's still uncalled for, especially at this price point.
