Yes I know, but the hpfp failures are "related to gas in tank" but if you read between the lines, when you put gas in the tank, you severely cut down on the lubricating properties of diesel! So, if the "fix" vw is wanting to pull out of their hats with the filler neck doesn't fix it and nhtsa keeps getting these complaints, and they are found to be unrelated to fueling, then the engineering analysis will dig deeper into the hpfp failure issue.

That's a huge "if", though, given the information at hand that points to gasoline contamination in almost all cases, the fact that this rarely happens in Europe where owners are more familiar with Diesel engines, and the fact that US Diesel fuel satisfies the required lubricity.

^^^ AND you KNOW FOR A FACT that all those replaced at YOUR dealer were all due to MisFueling? I know of NO Diesel Trucks that have had the failures our TDI's have had when "accidently" filling with GAS. In Fact I have accidently put Gas in a Diesel F350 when I worked construction. That truck ran a little rough, but the fuel system lasted another 200k Miles before a rod was thrown thru the block due to excessive weight on a trailer.

And I have not heard of Previous generation TDI or Diesel VW before the 2.0 CR motor came along with the issues either. In Fact My cousin has an 80s Diesel Cabrio and when he got it, the motor didn't run, Gas in the tank... He drained the lines, changed the fuel filter, put diesel in the tank, and it fired right up. It still runs today.

So, basically, we all know Gas is a killer, but it is pretty lame that the fuel system isn't nearly robust enough for the US market and our vast abundance of STUPID in this country. When the HPFP goes, it takes out EVERYTHING fuel system related. This is absolutely an oversight in the VAG Engineering groups.

So, again, if the Dummy Proof Filler "fix" doesn't bring the number of HPFP failures down. Does anyone think VAG will issue a TRUE Recall on our oh so poorly designed HPFPs???

No engineering expertise, even German, can overcome the stupidity of the USA customer. The problem is not the design, it is the customer.

Your Ford "example" is laughable.

Must Read, and the info is in the last paragraph that I thought was interesting, we are finally getting engineering to look into our hpfp issue!

The reason they are doing that is because Vw is tired of picking up the tab on wineing diesel owners because they grenaded their high pressure fuel pump by pumping gas into the Diesel engine and still expecting that Vw be responsible for their stupidity

Every single CR Diesel is like that - whether VW, Audi, BMW, or Mercedes. There is currently no other technology to produce the required high fuel pressure.

However, some of us have been wondering if a post-pump filter could be installed. The problem is that it likely has to be pretty big, so as to not reduce the pressure.
