You could leave the strut brace in place, but it is a little roomier to get at the back if you take it off. I just tightened those bolts until it was tight.

You will need an assistant to get the fly wheel locked in place, and an inspection mirror to figure out when you hit TDC. The instructions are pretty good, no huge surprises or anything

Original pump @ 120k. There's some slight visible scoring on the roller, and the crank as well. Some wear but nothing substantial, No indications that the pump was nearing failure or anything. It's difficult to photograph, but it looks pretty good. I like my new pump better, but this one could have broke the 200k mark for sure

Probably was the intake cleaning, but gas mileage seems to be up too! Last tank was 41.3 mpg with sitting in traffic 3+ hrs

That pump looks great. You've been using quality fuel for sure. It seems to confirm the fuel contamination theory vs. just wear and tear. I agree it would have lasted more. Thank you for the pics!
I have a 20k mile one for testing, with similar wear patterns, just less polishing of sidewalls.

I was sent the fuel pump warranty extension letter, like everyone else, 2-3 years ago. But today I just received another letter saying specifically that the fuel injectors would be covered for 10 years or 120,000 miles. I assume this extends, and does not simply supercede the prior fuel pump protection letter.

Looks like with the GM, FCA, and other diesel fuel pump class actions in the news this fall, BMW thought it would be a good customer retention strategy to make it clear that they're at least extending the coverage. My wife's Mercedes, and my 328d, both have the Bosch 0445010553 or CP4.1 pump that can self destruct with ultra low sulfer diesel, especially if water gets into the fuel. She has yet to be told anything by Mercedes.

We're both using DieselKleen which has an extra lubricant for the fuel pump, so maybe that will save us $10-15k each.

Mind taking a snap of the letter?

The pump generally destroys the fuel injectors when it goes, but I have not received a separate letter covering them, not sure if they had any issues on their own. I'm past 120k at this point, But still on original injectors.

Is this only sent to original owners or even 2nd or 3rd owners? We just bought a 328xd wagon with 102k miles from a BMW dealership and would sure like to know if this would be covered. We purchased an aftermarket drive train warranty which includes the HPFP, but I was planning on dropping it after I could get some miles on the car on my own. Now I am starting to thing it would be better to just hold on to it.

I have been working on a solution to the CP4.1 issue and finally the prototype parts are here! Everything is based on on the same concept as the "disaster prevention kits" for the CP4.2. I will be installing into my ride this weekend. I also have a 2nd set of parts that I would like to have someone test out in their rig. Any volunteers?

If testing is successful, I plan on selling these as kits for around $200.

One of those 2micron kits would work just fine. I am planning on using a derale filter mount with a Cim-Tek CIM300BHA01 1 micron filter. Only thing I still need to source for that is a 1-12 to 1-12 nipple to mount the filter.

Interesting to see this letter. I was one of the unfortunate people to have a hpfp failure at 42,000 kms! My car is now at 82k with no further issues, however, I haven't received any recalls/waranty extensions about the fuel system.

I'm curious... Anyone in Canada receive this letter or anything similar regarding the fuel system?
