We're talking about vehicles BUILT in 2011, not a car built in 2010 with a 2011 model year slapped on it.
Then point out the 2011's that have the build dates posted.

Have there been 2011 models with the HPFP problems not as a result of gasoline/diesel mix up?

That's the million dollar question, but we're not concerned about 2011 models. We're concerned about 2011 BUILD DATES. SO far, no answers.

The build date of the HPFP is the important point. If the pump in the 2011 build date car is the same as the pump in the 2011 with a 2010 build date, the date doesn't make a difference.

El Dobro, it's called wishful thinking. Dariof thinks that his 2011 is immune to the HPFP failures because he is creating a subset of TDIs that his car is included within, and claiming victory based on that.

In a year, he'll give up on that. Just like the 2010 guys, just like the 2010 Golf guys, just like the 2010 Golf guys in CA, just like the 2010 Golf guys in CA with blue paint.

That's what I was thinking. Not too long ago it was the 10 guys saying there's had a new pump and there weren't any failures etc...

You're out of your mind. I never said anything like that dude.

If you don't understand how to read, what I said above was I wanted to know if any TDI's that were BUILT in 2011 were having failures. That's an inquiry to gain facts...not some "victorious subset" as you conjured up.:rolleyes:

In fact, I'm getting ready for a trip and I'm taking the Mercedes diesel instead of the TDI because I DON'T KNOW if there have been 2011 build date failures. I won't take the chance until there are factual answers. That's a far cry from "claiming victory!"

I just got back from a nice journey along the eastern seaboard, about 900 miles. The 2010 Jetta was a great drive, got upper 40s-low 50s mpg. I've been running a 2% BD blend. Don't live in fear, drive your car and enjoy. There are no guarantees no matter what you drive.

Statistically you are more likely to be rammed by a Tahoe driven by a text-er, smashed by a drunk driver in dented Taurus or rear-ended by Ford 250 Super Duty 4x4 powered by testosterone.

I love imaginary stats as much as the next guy, but based on all available information, I very much doubt your specific example is more likely than a HPFP failure.

Yes I had two of them. The last failure was fuel from the dealer which I was told was of the highest quality.

I have been talking to some people at work about my failure. And one guy his brother works on Diesel tractors for a living and claims the HPFP is a common failure on diesel vehicles. He states "You should never run a tank empty because of all the bad diesel at the bottom." I don't know about the other failures but I drove my TDI until the fuel light came on every time and would drive for another 20 miles. This is just hearsay but i am curious if there is a connection.

The fuel at the bottom should be the first to get used. The fuel at the bottom of the tank at your local station may be another issue. I generally don't let my tanks get much below 1/4. A concern with running too low would be the possibility of sucking air into the fuel system, perhaps impairing lubrication of the hpfp.

If I had to guess the diesel in the bottom of the tank probably gets mixed up pretty good when you fill it up the next time. I dont think it layers.

Could the fuel somehow have moisture and that float to the top and when the tank gets empty you would be pulling some water in or something like that?

Or could the diesel it self separate? the good stuff float to the bottom and bad stuff float to the top? (whatever the "good and bad" stuff is i dont know. I am mainly a gas man and I know all this ethanol eventually breaks down into water)

Water will always settle to the bottom of the fuel tank in diesel fuel, it's heavier...that's why we sump our JetA fuel trucks daily. Condensation on steel tanks is horrible but poly tanks now reduce the accumulation rate significantly in cars and trucks. I chased a prematurely plugged fuel filter on my Cummins once and after dropping the tank, there wasn't a spec in the tank or at the bottom...whatever the source of rapid filter plugging was entrained in the fuel pumped into it and and made its way through the system as a fully blended fuel/gunk mixture. That's why good fuel filters are sooo important on diesels.
