@ CleanKM As far as the pump goes, 0445010517 is the latest version of the pump from Bosch. It's somewhat improved but I don't think it insures that the system won't get destroyed if it goes out though.

@Richard Ellis I bought this kit. Had everything I needed for about $50. The camshaft locker isn't needed but the other parts are.

These are the numbers the auction lists:

Crankshaft turning tool OEM 116480
Camshaft locking tool OEM 118760
Pump sprocket support sleeve OEM 118740 and OEM 118741
Crankshaft pulley locking tool OEM 115320
Two tensioner locking pins

Bosch part number 0445010517 is not the latest. That one stopped being revised after October of 2015. Next design came out in July 2016.

The newest Bosch number for this car is 0445010783, which is BMW part number 13518597819 (and a 03 minor revision underneath that part number)

Dealer quoted me $800 OTD for swapping this out while they are doing the EGR Cooler Recall work. This seem overpriced to any of you who have done this, or had it done?

I stand corrected! Maybe I didn't have the latest and greatest. Still comforted knowing it's been replaced. Does the new one prevent catastrophic failure?

$800 seems pretty fair to me for a dealer price. I'd count on 4-6 hours labor if I did it again and they're usually ~$200/hr. The part Enabled mentioned lists for $1100, so you may be at $2000 if they provide the part as well.

Does anyone know if the X5D (2015) is plagued by the same HPFP?

Same HPFP generation, except the N57 has a dual head/dual piston system for more volume.
The updated pumps exist for N57 as well.


Regarding updates, I don't think it will prevent system failure from intentionally running any trash fuel, but it will make it a lot less susceptible to major damages. These simply were not designed to run water through them or gasoline.


I have a good detailed list of updates, but here are some main ones:
-DLC coating on cam, rollers, piston, and cylinder walls
-mesh filters inside intake and return lines, with a modified bypass system
-larger roller size for the cam follower
-an internal fixation system to prevent the internal piston from spinning


I have a few pictures of these, I will have to make time to upload sometime.

Called around to several dealerships. The interesting part is that one said (after speaking with a tech) that if it hasn't grenaded yet (I'm at 116K), then chances are that mine isn't a faulty one. Thoughts?

I'm still leaning on replacing it, especially if the latest part has the filter to prevent damage for the whole fuel system.

I wouldn't consider replacing it till you are out of the 120k mile warranty that is offered by BMW. My 2014 535d fuel pump cracked on the left piston cap and started puking fuel. I am in the process of trying to get this taken care of under the extended warranty but BMW is trying to deny the claim even though its clear that the HPFP failed. Here are some pictures of the crack and now the cap is completely off with metal shavings found in the piston cap.

Ah, you're the one that Anthony has been telling me about. Shoot me a PM, I'd love to hear a bit more about that car. Didn't realize you were that close.
