In the future, if you have another issue of this nature with your dealer, I suggest asking them to set an appointment with the Regional BMW NA Service Manager.
Typically this works the other way around - dealerships are HAPPY to throw parts at the cars under warranty. They make money and pay the bills, at BMW NA's expense.

Always used good reliable gas stations, and Shell Vpower diesel when available... But I suppose I should've been more on top of additional additives to lubricate the system. I was planning to replace my HPFP as a preventative measure at the 130k km mark (which would've been 90k on the first replacement pump). Dealership advised me a couple hours ago of a 17k CAD quote to replace full fuel system. I have escalated through BMW Canada and am waiting to hear on their verdict. I've had two oil changes done away from the dealership at a German Auto Specialty garage... hopefully that doesn't screw me. Frustrating that owners in the US have received extended warranties on the HPFP, yet I have not heard any owner in Canada receiving the same letter. Anyone on here from Canada who has received the letter, please let me know. If BMW denies me a paid fix, I'm not sure what I'm going to do. I imagine a local garage would be 10-12k or so... Has anyone had a pump fail, distribute metal through your system and then fix everything yourself? What kind of nightmare am I looking at? Can you flush certain components and reuse them? Or is it best to buy all the parts and rebuild the system as the dealership says is necessary? I wanted to get 250-300k kms out of my car.... not quite 1/3 of the way through my goal, and I've eaten two HPFPs.... after being a "victim" of VWs Diesel-gate which lead me to a bimmer...... :/ Side note.... It sucks that I still love (mostly) everything about this car lol |

Yes it's possible to replace just the 4 injectors, HPFP, rail pressure sensor, rail pressure control valve, and fuel filter; flush the rest. If you had water in the fuel (highly likely) then you may need to replace the LPFP since it gets damaged by water.

This is why when folks ask me whether I'd recommend a modern diesel, I respond with an emphatic No.
Between the fuel system worries and the emissions controls that will bugger it up, it's just not worth it anymore. The fuel savings and good times when they work properly is just not enough to offset the expensive headaches at times likes these. Having been through a similar situation with our Bluetec (several years ago, same cost) I can relate to your frustrations. Good luck, wish you all the best.

I got to thinking, and the best way to prevent this would be to prevent water from getting to the pump.
Old VW TDIs accomplished this by using an upright fuel filter that had a drain at the bottom, for draining out water. These are part number 1J0127401A and they were used on cars with both draw through and push through from a LPFP. I had just changed it on my 2003 Jetta a few weeks ago, and I drained the bottom. Sure enough, some water came out.

Enabled , good point on water being the likely issue. On my previous TDI with the PD engine, I had installed a 2-micron CAT filter setup. It did not have a water separator but I had never found water in my fuel filter before then, so I didn't worry about it.
I had found dirt and other contaminants in the filter, which is why going to 2 micron rated filter was all the rage back then. Plus they were cheaper than VW filters and could go much longer mileage intervals. I've thought about adding a similar setup to the X3d, but just not quite sure how to go about it. Hoping that getting fuel from reputable places and using a fuel additive every tankful will prevent issues later on.

There is likely some room back there by the ECU?

Interesting concept. There might be enough room, although I'd want to secure it somehow so it doesn't put any pressure on the lines.
Speaking of pressure, would you anticipate there may be issues with the fuel pressure supply by adding another filter?

However, a device that is sold with excessive cost or filtration capabilities that can select out individual bacteria cells may be overkill. First, you don't want to add resistance to the flow. The fuel is already being filtered. I know that saying 1 or 2 micron filtration is "optimal for the car" in theory, but in all honesty, it won't stop water itself, and most particles will have already been caught. The issue that can come up would be stressing the LPFP a bit with it. It's awesome to find others looking into it. The VW filter does just that job, it separates water, and it's cheap. It also has a screw off bottom that you can take a sample of your fuel/water. Neither would be wrong, but I definitely wouldn't want this situation to morph into an advanced contraption, when something simple would already work. Anyways. These are just my opinions. Obviously if either blocks water from reaching important components, it's a win. A large amount of water entry will still get through any water separator. But if that's the case, there will be a lot more problems anyways.

Thanks for all the input guys.
After some back and forth with BMW and some escalations with a BMW case manager, they have offered to pay 80% of the total cost of the fix. So roughly $3000 out of pocket. Then, as with all the BMW genuine parts, you get a two year warranty on all parts and labor that they change. I figured I would be in it for 3-4k worth of parts to do the work myself, so I took them up on the offer. Complimentary loaner has been provided and they should have my car back on the road within the week. This brings me to my next question... What preventative maintenance are guys doing aside from a fuel additive (which I need to figure out which to use) and changing the HPFP on a set km interval? Nice to see people are trying to come up with some system upgrades for water separators or screens to catch the grenade fragments... but nothing seems quite available yet. |

From looking through the forum, I thought the main reason for the failures of the HPFP was due to the ratio of bio/eco-diesel in North America increasing the wear on the pumps... hence the reason for the lubricant/additive in the fuel? Is there anything I can ask the dealer to look at to determine the cause of my most recent failure? |

Biodiesel (technically) is actually more of a lubricant than straight dino diesel when properly processed and filtered. Trouble is, that's where contaminants can appear, including water.
Water will kill a pump in short order, simple as that. Biodiesel hurts in other ways, over the long term. It creates deposits on the injector tips that can clog them up. Again, the source of the fuel (whether biomass which is typically waste veggie fryer oil, straight clean veggie oil or some other source) counts in terms of quality of fuel, followed by the processing, filtering and storage setup for the fuel itself. The state next door (Illannoy) subsidized biodiesel, so almost all the diesel pumps have some %age of bio. There are probably a few pumps in the entire state that sell straight dino diesel; the rest are all bioD.

I did a proactive change of my HPFP 2 years back, which may not have been necessary. I don't think we had identified water as the cause of failure back then. I did recoup half the cost of the repair after I sold the used pump though, so it wasn't terribly expensive and it made me feel better at the time . |

Well, it looks like LCI/later 328d's are now included in this warranty extension (I had posted before how BMW's system didn't include me in the earlier one when I checked the website). I just got a letter from BMWNA saying 2017-2018s now have a 10yr/120k HPFP warranty extension.

Same, just got my warranty extension in the mail as well. So far, the EGR cooler, injectors, and HPFP have received the 10yr/120K extension. VIN still doesnt show my car under the recall either.

My understanding was it was the ultra low sulfur fuel provided less lubricity vs the EU fuels. Bio diesel is less energy dense (I lost 10% mpg on it) , but more lubricity than uS diesel. I understand it is also more hygroscopic and possible more likely to gel in cold weather (not something we get here so I’ve not paid attention to that aspect)
