I think mines an 11/13 build.

hey, my M235i was built 11/13!

Yup. Ask Ford how "blaming the supplier" worked during the Firestone-Explorer recall. Ford paid a steep price as the buck stops there.

Given the massive failure of the N54 fuel pumps and turbo wastegates getting stuck requiring twin turbo replacements this is just another reason to be prepared to pony up big bucks in long-term ownership costs buying a BMW.

So if I'm looking at this correctly, only 10 of the very earliest Gran Coupe's are being recalled and my GC which was manufactured in November 2014 is in good shape, yes?

Weird. Production for 2015 4 gran coupe shouldn't have started by March 2014 though?

Does the recall affect out of warranty vehicles differently than under warranty vehicles? I just crossed 50k and I'm in the production date range of affected vehicles.

[deadlyrhythm]

Why is everyone going on about this in the E Series? Completely different fault. Just happens to be the same pump. Different failure mechanism tho

Thought about that, but there were a few GC's making the rounds at the time (I saw one at the NY Auto Show a year ago this weekend) and there are only 10 in the world affected by the recall.

So perhaps those early production cars were eventually turned into loaners or sold as CPO executive specials and are out in the wild, still need to be recalled and corrected.

Bosch is a good supplier but they seem to suck at fuel pumps, spark plugs and DMTL modules.

Bosch usually makes great products!

I started to feel that every turbo engine from BMW will have this problem!

The original reporting referenced defective nickel plating. Sounds like a manufacturing issue as opposed to design.

Warranty has nothing to do with recalls. Safety is the issue so BMW wants to have all its cars corrected.

Recall doesn't say if low pressure or high pressure. But here is the low pressure pic from real OEM

Recall states nickle plating flakes get stuck in the impeller.
High pressure pump has no impeller, so its the low pressure pump.

Pump is also only a piece of the part you see in the pic as that includes the one fuel level sensor.

They will most probably only replace the pump and filter.
Quick easy job. Most will probably be done at their next service as with many other easy recalls.

When will this actually start showing up in local dealers systems? Mine failed, car cranks but won't turn over, but the dealer's system doesn't show any recalls pending for my car.

30 April according to the report.
Dealer can just submit a PUMA case for your car that has problems and get the same work done before the recall becomes effective, if its the same problem and the car is under warranty .

Interesting that BMW still uses their "beta turbo engine" even today on some cars like the z4

The old e9x pumps are the same exact pumps used on the n55. Same goes with the injectors. It took them long enough to get it right. Ever since my last replacement at 18k miles I haven't had an issue and I'm on 96k miles now n54 FBO

Glad my 3series is diesel and isn't affected by this according to the recall documents.

The diesels had more than their fare share of major problems over the years

It's low pressure. Nickel plating is on the suction casing and cover of the in-tank fuel pump module. Fuel pump design is of turbine variety - feel free to look it up if interested to learn more.

Nickel plating is used to avoid wear due to cavitation / various fuel blends E0-E100 / and slower spinning pumps due to ERFS. (Electronic returnless fuel systems - PWM for fuel pumps)

Sounds like a process issue to me.

No worries - Bosch/AFCO know what they are doing is probably already fixed.

[raysspl]

All the best to those part of this recall

[r3dbimmer89]

Hmmm this sounds familiar.... at least this time they seem to have figured out the root of the issue from the get go.

[jadnashuanh]

It would be nearly impossible for BMW, on incoming inspection, to tell if the nickel plating was to spec or not. It could be as simple as a contaminated cleaning solution prior to plating, or the temperature being off a little, or the concentration of the materials or the timer, and many other numerous factors.

IOW, only by long-term endurance testing would this show up AFTER it was built unless you were sitting in the plant where it was built and monitoring every detail carefully. Part of that process is to take an occasional part and run it through endurance testing, but results, obviously, take awhile.

Bosch (based on what was said) discovered this during their (probably required, certainly prudent) testing of their delivered products. The design works, but when not manufactured properly, it may have premature failure.

There are many thousands of parts in the car, and while BMW assembles it and is responsible for the entirety, they rely (as does every manufacturer) on their suppliers holding up their end.

Few manufacturers, if any, can afford to design and build all parts used in their cars. Things have moved a long ways from the vertical conglomerate that was pioneered by Ford, where they started with raw materials and made essentially everything in the ModelT. The current BMW is a long ways from that, and it's a good thing, too.

SOme things can be detected on incoming inspection, some can't...this one couldn't be. It's being resolved. Calm down...

[capt_slow]

Sigh...

I wish Bosch would step up to the plate for the HPFP on the VW TDIs.
