@ 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?

[kdog_x]

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?

[Enabled]

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.

what is your source for this information? real oem shows superseeded part numbers but nothing on what has been updated.

Here it is, threaded into place. The actual BMW tool for this task is a 2 piece assembly, so your tool may not match but they work similarly. This MUST stay in place while the pump is removed or you will need to pull the engine and reset the timing





Then remove the 4 bolts that hold the bracket to the cylinder head and the pump. Followed by removal of the bracket, it's a tight squeeze, but it can be worked out of there



Remove the electrical connector for the pump




With the bracket out of the way, there are two bolts that hold the pump to the cylinder head, one here and one down below.




Loosen the last bolt holding the pump through the special tool in the back and work the pump forward off of the cylinder head.




And there it is with the pump removed

Do you know if it's possible to replace the quantity control valve on the HPFP without removing the manifold?

Hi There,

I have a 2015 BMW 420d Series, think N47 Engine, not sure, anyway i have read your steps and folllowed them althought i seem to be struggling removing the pump, its free and it come away from the head slightly but just cannot seem to free it. Do you have to put bolt the hpfp tool in until it basically stops im just dubious taking it out a few turns and causing issues.? or would you back the tool off a few threads, im guesing the bolt that you undo thats on the end of the pump doesnt fully remove as mine stopped dead after undoing so far?

HELLLLPPPPP!!!

Sounds like you're on the right track. The bolt that threads in the back of the pump will run out of room to be backed out. The head of that bolt is larger than the hole in the special tool so it won't come out.

So you need to pull / twist / pry the pump forward a little bit to give the bolt room again, then loosen the bolt a little more. I believe I needed to do a bit of a clockwise rotation while pulling it. It takes a bit of force to pop it off the sprocket.

You should not need to loosen the special tool to remove the pump.

Yes, pretty sure the bolts were accessible with the intake manifold installed.

Youre a diamond buddy. Its backed all the way out until it has stopped. It does rotate clockwise and anticlockwise.

Also on my 420d the bollom bolt on the hpfp was a pain to get to and had to go underneath as my oil filter huosing is in the way. any easier way as you cannot got it flush onto the bolt.

Quick question, locking off the flywheel, is this just to help udo the hpfp bolt as without it the whole sprocket will spin?

[kdog_x]

Yes, I remember needing a precise combination of different size extensions and my ratchet that works on a 45 degree angle to remove the bottom bolt. It took some maneuvering. Dunno about the 420d, but I got mine from the top.

I think there's a hole in the flywheel that the special tool needs to go through. If it's not locked with that pin, the hole is out of alignment, and you can't insert the tool.

Keep in mind that if there is a lot of pressure on the cam and sprocket from chain rotation, it will not release and slide off the keyway.

What would you suggest?

Any help welcome, it will turn clockwise anti clockwise easily, just wont come out, the bolt is backed till its hit the stop.

Sorted Crowbar helped

[Rayment87]

Can you confirm when replacing the pump which part number is the crucial one?

[kdog_x]

I believe I used a pry bar as well. Its a tight fit.

0445010588 is the Part Number of that pump

[Enabled]

8511626 is the BMW part number. Bosch one is different.
