I am hoping that the better pumps will be a permanent fix (or at least good for 100k+ if doping with lubricity agents).

It is really screwy that a HPFP cannot be manufactured. I would pay more for one that doesn't shred itself apart. How about aftermarket?

So $800-1K for a timing belt, $1800+labor for a fuel pump all while staring down both barrels at a possible DPF replacement at anywhere between $1-2K.

Yeah, that's realistic.

Is the HPFP itself really $1800?

It can be had for under $1000 discounted, but as a maintenance item? BS. There goes your fuel savings out the window.

Once the aftermarket re-builders get there hands on a few it will probably be around the $1000 mark

Impex lists the VW list price on a 03L130755A pump as $1265.

And, I still say, aftermarket (that is, non-Bosch) isn't really the true answer - if there's a 1800 bar version of the Bosch CP3.2, that's the answer. (Or, for that matter, use a CP3.3, and just have the thing bleeding fuel off all the time. You'll have enough fuel for 450 hp, but you don't have to use it all...) That's a pump that is more tolerant of US fuel.

Also, $900 for a VE pump has no relation to what a CR HPFP will cost.

The crack spread hit $.70 per gallon (i.e. difference between rug and diesel). There is no savings for the lower mpg CR engines right now.

I don't hold one ounce of sympathy for VW. Is the claim that VWOA is/was too stupid to understand that the USA runs state of the art 1950s infrastructure. They should have expected it and developed a pump for it --- oh wait, they did in every design but the CR's .........

Actually, the 2.0T eats HPFPs, too.

(IIRC, the reason for gasser HPFPs dying is ethanol.)

I wouldnt be so sure about that. Pensacola made a far superior update to the Stanadyne DB2 for my 6.9 IDI. The original lasts about 160.000 whereas the Pensacola with updated internals will outlast the original for many more miles.

Default 3x designs

BMW had a recall on its HPFP thanks to a 20/20 report on ABC. I spoke to a BMW rep they are now on there 3rd replacement pump since the recall the others all failed. As per Friday 2/11/11 one of there salesman has 12k miles in just under 2 months an still working ok.

I also recently spoke with a Regional mgr for Bosch an he will get back to me on the VW issue sometime this week.

I called VW of N America on the HPFP problem, well they state its a fuel contamination water or gas mixed in the diesel fuel. I cam back and said well how come there is no contamination on the 06-08, only 09-10 her answer was pure silence.

The more people complaining the better off for all TDI owners

Unless there's a failure mode I'm unaware of, it can't be ethanol or other fuel related reasons, the FSI engines have oil lubed HPFP cams. The newer TFSI engines have supposedly solved the problem by switching to a roller follower.

+1 This is real problem they should work on and the pump to.It's one thing for the pump to fail but to take out the whole system is a downer.

I am on the sidelines in purchasing a new TDI Wagon because of this issue. I do believe VW makes a great car, will get this handled and will have a permanent fix, but I also believe it will take a little while longer for this to happen.

However, there are way too many posts on the subject, both within this forum and outside sources.

Although nobody is exactly sure of how widespread this issue has become, there is no doubt, it is an issue.

These failures are not a state of mind, and I highly doubt they are all caused by diesel enthusiasts "accidentally" putting gasoline in their tanks.

My local dealer told me they have had 4 failures, and all were because the diesel purchasers didn't know any better and put gasoline in the tank. I know that is not true, and it fits nicely with VW's stance of "plausible deniability."

In the meantime, I'll continue to drive my German Diesel SUV around until I believe VW has fixed this issue.

Doesn't matter. Even if it were true, mis-fueling is going to happen.
And it can happen at the terminal, when re-filling the retail
station, or when filling the vehicle.

In the past, it often resulted in nothing in particular,
or maybe a blown head gasket. It did not cause mass
destruction of the fuel system.
_______
The HPFP is apparently not designed for the real world
(US lubricity or predictable mis-fueling - or both).

Unless you filter the fuel LEAVING the high pressure port of a HPFP, a failed pump will tend to destroy the fuel system. There are very few options to filter the fuel leaving a HPFP at 1800 bar.

Perhaps a sintered bronze filter integral in the high pressure fuel line between the HPFP and the common rail would withstand that kind of pressure, but not much else would. This would not be a maintenance item, but a fail safe item. The metal particles leaving the trashed pump would lock up the bronze filter and stall the engine before the metal reached the common rail and the rest of the fuel system.
