Bought '09 E70, 3 weeks later catastrophic HPFP failure...

[Eric_S]

Well, isn't this a lovely first post.

Bought from an independent dealer with extensive notes on service and repair history, all of which was BMW facilities. Felt pretty good, even though she's a 2009 and had 97k miles on her. The diesel engine ran great, had no standing or pre-existing codes to deal with, but has not received the airbag repair.

Set an appt at the local dealer for the 100k service because the wife wanted it dialed in and ready for the next 100k miles.

3 days prior to appt, vehicle has a stumble, then on comes the CEL. I have since learned the code that would have appeared, if they checked, was:

004CE7 DDE Misfire detected, cylinder 2

Wife is in town at this point, and drives approximately a mile to the dealer. Dealer states 'it's not a big deal', and never connects the vehicle to a diagnostic device. She is sent home, to return 3 days later for the 100k service. At this point we don't know that it was the 004CE7 code.

2 days later, vehicle completely disabled on the side of the road, requiring a tow, with a complete fuel system failure. 2 full pages of codes are thrown at this point per the subsequent investigation.

Dealer has reported this is a complete HPFP failure, with unknown upstream and downstream distribution of metal shards from the pump disintegrating. Apparently this is something that has been seen in the 335D's. Currently stating a $3500 repair to replace the HPFP and flush the fuel system, however it may not resolve the issue due to distribution of fuel pump fragments. Most effective repair per the shop would be to replace pump, confirm whether it is in fact repaired, or not. If not, complete fuel system replacement to include tank, lines, low and high pressure fuel pumps, hard lines, injectors, etc, for a total cost of $14,950. I have a printout of the complete failure list, but obviously all codes came about almost simultaneously with the major failure.

You all have owned these things, I'm new to it. Lay upon me a bit of knowledge. I suspect the dealer could have seen the early code and prevented a much more catastrophic failure.

Thanks for input or similar experiences.
