Recall 21V-586: High-Pressure Fuel Pump May Fail (N47, N57 engines)

Saw this posted on another forum, figured it deserves mention here.

BMW is recalling a large number of cars with the N47 and N57 motors for HPFP issues. It pretty much confirms what the common-rail diesel community suspected for years on the Bosch CP4 pump. Looks like we're all getting new pumps.

Quote:
In early 2021, it was shown that the valve lifter of a certain pump build level configuration has a higher tendency to be affected due to the use of biodiesel aging products and low viscosity fuel. Additional factors such as the pump’s roll and cam profile were thought to contribute to performance degradation and unwanted pump wear for this build level configuration.
2014-2018 328d, 328d xDrive, X5 xDrive35d
2014-2016 535d, 535d xDrive
2015 740Ld xDrive
2015-2017 X3 xDrive28d vehicles

Good on BMW for doing this. AFAIK, this is first time a manufacturer has acknowledged an issue with the pump. The issue goes back to the late 2000s with VW TDIs having the HPFP cam and roller disintegrating and requiring a full fuel system replacement. For years, VW has tried to blame the failures on bad fuel or misfueling and going as far as recalling cars to affix more "Diesel Only" stickers and misfueling guards. However, VW never admitted to an issue with the pump itself. To put this in perspective, the CP4 pump as been used on many Ford, GM, Chrysler, VW, and BMW diesels, all have had similar issues.

I saw this a few days back. Pretty good news for sure. 11,000 units seems kind of low...

My nearest local dealer is a disaster, so I'd have to plan this well.
The latest updated pump is a good thing to have for sure. I'll try to get a bit more detail as to what will go in.

I bet we’ll see nothing of this in the UK…as BMW will probably claim our fuel quality is adequate enough to mitigate failures…we’ll see!

Odd. My '14 328d doesn't appear to be included in the recall. Wonder if that 11,000 will increase over time.

My car isn't showing up either. I guess when we get closer to that Sept date we will start seeing the VINs pop up.

What I am interesting in seeing is the SIB for this recall and see exactly what are the repair steps.

The NHTSA link list the production dates for all affected models. 328D's from Jul 1, 2013 to Oct 11, 2018 are covered.

Give it another month. BMWNA wont be mailing the recall letters till Sept 20, 2021, so around then would be when specific VINs would be flagged in the system.

My 2017 328d just went full-time with an HPFP issue, it stalled and died on a road trip Sunday and again Monday morning. Check engine lamp is illuminated, and the drivetrain malfunction warning occurred both times. Engine fault 247500 and 247600 are present in Carly, and it idles a bit rough.

I spoke with BMW corporate and they did recommend I bring it in. I called my main dealer and mentioned my call to corporate and they pulled the active recall notice as applicable to my VIN. like others said, it won’t pull for you on NHTSA or BMW sites until after 09/20/21 when the bulletins are mailed out.

Before I called corporate I did go ahead and update all contact info which helped both parties ensure the VIN and notice would go to the right address. I hadn’t received the EGR recall notice which I should also address next week when the car goes in.

I think the abundance of B5 diesel in the midwest and high humidity has contributed to this, as the drivetrain warning has occurred at 42k, 53k, and 56k miles - but without further incident in those cases. I am at 60500 miles currently. If anything i’m hopeful that the timing of the recall and my engine issue is perfectly aligned so I get little or no bill and the problem is solved. I had planned on running this car to 150k, it was fine within warranty from new but this HPFP saga is disappointing. likely the last diesel vehicle I will ever own. Considering how ugly the iX and i4 are to me, probably the last new BMW I will buy for a long time. Keeping my E36 though and maybe getting an M2 CS.

I wonder if it will be a recall on every model listed. 11,200 units doesn't sounds like it would every car in a 4 year span, covering 5 different models. Maybe they identified a certain lot number of pumps that they will recall. I just rolled past 185,000 on the clock... so I may be on borrowed time with something else breaking anyways.

I did proactively replace the HPFP around 100k though, so if I had an affected lot number, I may not anymore.

My 328D is booked in for service this week. We shall see if they have clue one about this when I speak to them. To be honest I'd sooner delay the service if my car is on the hit list and get it all done at once.

I also wonder if the new pump requires a software update.

Any ideas on that?

No, because the pump characteristics will remain the same. It will be a pump with different coatings on the cam and piston, to protect from corrosion and fuel contamination.

Perhaps they can recall their faulty fuel tanks while they're at it.

Update from my dealer (finally) my HPFP was indeed failing so hopefully this updated part cures the problem for the lifetime of the car. Also hoping that due to this being a recall that any & all fuel system parts affected will be covered 100% by BMW. I'll update when I know more.

The dealers were notified in late August, so all of them should know about it. With 11,XXX total diesel cars affected however, I am guessing enthusiast market dealers will be more responsive than those who primarily trade in higher-spec/M cars but it's in their systems at least.

Was sincerely hoping that my car would not be affected, so I would not take it to incompetent dealership of mine. But alas!

Nothing on my car yet. Also looks like some affected cars will be given a 10 year, 100K warranty extension (from original in-service date) on the pump too.

yep. but I already fixed it myself...

I had my HPFP go out on me this past February. BMW in Vista CA wanted $12,000 USD to replace the entire fuel system. I ended up figuring out how to fix it myself for about $4,500. I wonder if they will cover that cost? anyone know how this recall will impact owners previously damaged by the pump actually failing?

TREAD ACT CUSTOMER REIMBURSEMENT PLAN
(BMW of North America, LLC)
If you have paid for the repair described in the attached letter, and you would like your expenses
to be considered for reimbursement, please contact your authorized BMW center. Expenses paid
to repair facilities outside of the BMW center network will be considered; however, the repair
procedure must meet BMW standards.
Your authorized BMW center will request a copy of your owner notification letter, as well as your
previously paid invoice. They will then inspect the vehicle (if it is still in your possession) prior to
submitting a claim on your behalf to BMW of North America, LLC for reimbursement.
Please note the following:
•Only a repair that is the subject of this safety recall is reimbursable. Consequential
expenses such as towing, rental, accommodations, damage repairs, etc will not be
reimbursed.
•The Manufacturer’s Suggested Retail Price (MSRP) for BMW Genuine Parts will be
considered as the guideline for reasonable part charges.
•Repair labor, taxes and hazardous waste disposal, when previously paid, are eligible for
reimbursement.
•Expenses for repairs performed more than 10 days after the date of the last owner
notification letter sent by BMW are not eligible for reimbursement.
Your authorized BMW center should be able to answer any questions that you may have
regarding your qualifications for reimbursement of a previous repair. If you qualify for such a
reimbursement, your BMW center will also be able to advise you of the manner in which you can
expect to receive reimbursement.
Your authorized BMW center should be your primary contact on this issue; however, our
Customer Relations and Services Department may be contacted at 1-800-525-7417 for any
special assistance that you may require.
In special situations where your authorized BMW center cannot be of assistance, you may submit
your written request for reimbursement to:
Customer Relations and Services Department
BMW of North America, LLC
P.O. Box 1227
Westwood, NJ 07675-1227
If you intend to submit a request for reimbursement to our Customer Relations and Services
department, your vehicle (if it is still in your possession and was repaired at a facility outside of
the BMW center network) will need to be inspected at an authorized BMW center before a claim
can be accepted for consideration. This is to ensure that prior repairs at an outside facility meet
BMW standards for recall completion.

Still nothing on my 09/14 build date f31d.

Wonder if there were certain batches of pumps only that are targeted.

I am still curious as to what exactly is different in new pump. Heard a mention of improved coating materials on the roller and other components. Wondering if there are any additional updates. Anyone privy to that information by chance?
