Hi all -
After reading some of the previous threads, I see that high pressure fuel pump issues have been a problem in the past...especially in the 523i and 530i. BMW thought the problem was fixed but it's showing up again this time in my 535i.
Sometimes when I start the car, it take 3-5 seconds to start and a warning message comes up on iDrive which states; "Engine malfunction. Reduced power". At first I thought it was a problem with the turbos. I took a short drive after one of these episodes and the car seemed a little sluggish but it was not the turbos. They are fine. Took it to the dealer who ran diagnostics and determined it is the high pressure fuel pump. They were surprised and called BMW in Munich since they thought this known defect had been eliminated. Dealer says this is a big job requiring them to have the car 2-3 days. They can't get me in until the 27th of Nov which is okay as the car is running fine and this is only a problem once in a while...which seems a little strange. I would think it would always be a problem vice only popping up intermittently. At any rate, they only have mini coopers available as "loaners" at the moment which may be fun for a few days...hope it's an "S".
Any other 535i owners experiencing this problem?

Be careful though, you don't want it to cut out in the middle of a left turn at a light with cars bearing down, or the expressway.

Ace sorry to hear this man, keeping my fingers crossed it's not a wider issue.

Ace90 - I don't think you are the only one with the continuing fuel pump issues. I have seen several similar posts recently.
Mods - should we consider making this known issue a sticky so we can track this situation? Also, is this HPFP only used on the I6's (seems that's the only posts I have seen) or, is the same pump on the V8's?

No definite answer if BMW switch vendor last summer, some say Siemens is no more and BOSCH is in but that's unsubstantiated.
I've followed this issue on e90post.com but the problems seem to peak around Feb of this year and less now. Not sure if because BMW uses better batch of pumps or oxygenated gas for winter is not in circulation yet.
Ave90 are you in Germany, I thought you guys have better gas than us here in America????
