Anyone seen long term solutions for this yet or is the HPFP that is now being used actually different than the recalled 4.1?

It might have been updated since when I entered my VIN of my '17 car in the link on the previous page it said my vehicle isn't involved in any programs (so the HPFP extension doesn't apply to me).

It will still be a CP4.1, otherwise then the control (DDE) would have to be different, or a special flash.
We can just hope Bosch got their hardware fixed.

Well the DDE is definitely different on the LCI 328ds.

That's an interesting fact.
Did some realoem checking.
The superseded CP4.1 pump is still the same part number across LCI and non LCI though.

• There are no diesel pump recalls for the BMWs that I know of.
• Second, any change in part should coincide with a change in part number, which would be seen in realoem, and also coincide with when the change updated on the production line. So if your HPFP number is the same in realoem, there is no update part.
• There are no product solutions for the BMW. But since these pumps are used in Powerstroke and Cummins, there are solutions in that market - both bypass kits and CP3 downgrades. Not seen anyone figure this out for our BMWs.

Here's some reading for those that want to look at this issue from outside the BMW word: http://www.dieseltechmag.com/2017/12...s-the-cp4-time
Below is a photo of what is in one's fuel system when the HPFP grenades.

Happened to me two nights ago. 2015 328d with about 35k miles. Died on Ortega Hwy at night, leaving me stranded. Talked to my advisor today and he said fuel pump and $10k repair with all fuel lines replaced, etc., but that they were still confirming. Haven't discussed anything further yet.

They should be finished in a day or two with the repair. So far, advisor quoted that it's a 'big job' and about $13-14k. Covered under warranty and no hassle there, but I was hoping to keep this car long term and now I realize that I'm driving with this ticking time bomb.

Did you get your vehicle back from the dealer?

Just curious what all they replaced? Seems a little steep that it would be a $13,000 bill. At dealer prices it's $1200 for the pump, $600 x 4 for all replacement injectors. That's $3600 plus labor... Not sure if the lines are crazy expensive? You would think they could flush those out. Or do they have to replace things back in the tank as well?

Yea, curious too, especially since injectors were $80-$100 a piece a few months ago. Stocked up.

I should have looked at the HPFP price then too...

When the HPFP grenades they replace EVERYTHING that fuel touches. Lines, tanks, pumps, filters, injectors......EVERYTHING. That 13k is in the ballpark for a HPFP grenade.

[CO_Steve]

A couple of questions. Has everyone received the letter? I have not. Second, does this warranty apply to the entire fuel system replacement required with pump failure? Not very useful if they cover the $1200 pump and you're left with the other $10k in parts.

Geez, I knew the injectors were left unprotected just due to the design of the HPFP and the high pressures involved. But if they replace everything in the tank as well there must not be any protection on the return line so it just sends the shavings right back into the tank. The in-tank pump should have a filter on it, but I'm sure trying to clean the shavings out of the tank out would be a fun job.

If I don't sell the car it sounds like this is pretty much going to be required maintenance at 120k. If I do replace it I'll have to post some internal pictures... definitely wondering if the internal cam would be worn at 120k if it hasn't failed yet or if it just implodes all at once when the roller turns sideways to the cam. That does seem to be the common failure point once it does go. I wish there was some info on what changed when BMW superceded the part number in 12/2016... I know my pump is original from 2013 when the car was built so it would be nice to know if they improved something in the design that would make me feel good about replacing it proactively.

When the VW commom rail CP4 HPFP issues started coming up, VW blamed misfuelings with gasoline. I wonder if it was true, and how common the failure really was. Switching to VW will put you in the same fuel pump situation.
I am hoping that Bosch's mistake isn't quite as common.

If the updated part number isn't affected, then that would be good news.

[kdog_x]

I sent Bosch a message asking if they could advise whether anything was updated with the part number change. Not sure if they will divulge that info but I'll update if I hear anything back

[kdog_x]

Bosch got back to me pretty quickly, I guess the 098 number is the manufacturer refurbed version of the pump. No difference between those part numbers.. no idea why BMW changed their part numbers in that case, unless they just started using rebuilt pump's. I guess I'll have to look under the hood and see what number is on my current pump if it has a bosch number

[rbreding]

There was an aftermarket secondary fuel filter that was made for the cp4 VW. I forget the name but it was plumbed so that if the HPFP grenaded that filter would catch the filings instead of circulating it back through EVERYTHING.

Not sure if adding a filter to the return line would hurt anything with the restriction, but it certainly would be nice to save half the fuel system when the HPFP goes. If we had the CP4.2 style pump I would think it would be fairly easy to use one of the "disaster prevention kits" available for diesel trucks and modify it to connect to the BMW plumbing. I have not seen any kits for the CP4.1 pump though.

Our previous 135i was a different story though.

Thank you for sharing! Just to confirm, you got the letter (and 10 year) for your 2014 diesel?

Did anyone else get this letter for diesels?
I just received one yesterday for my F31 VIN number from BMW group.

I know that these HPFP issues were a dime a dozen with the 335 petrol engines but have not heard of any issues with the Diesel engines and the HPFP.

Anyone here have any issues with their diesels?

Sorry for the potato quality of images

Thank you so much for posting the letter! I just bought this 2014 328d (3rd owner) and I think my HPFP just started its death spiral. I am trying to confirm my 14 328d really has the HPFP extended warranty before bringing to a dealer otherwise I'll just use my usual trustworthy mechanic.

Type your last 7 of VIN there to find out. This is the reimbursement website.
