Great work! Did you locate a reseller for these pumps?

Not so much. They are for sale in England for sure. When searching for the part, remove the J at the end, it could be one of several letters at the end.

Here is a more comprehensive answer. when searching, look for these part numbers.

VW or Audi

06D 127 026

with this letter at the end (eg: 06D 127 026F, for instance)
F
G
H
S
R
J

or leave the letter off and see what you can find.

Opel

12596968

there's just a ton of these darned interchange sites showing up in my googling, with no pricing, but they can be useful to find alternative part numbers

http://www.autopartoo.com/oem/vw/06d127026h.html

Also, I appear to be stuck in a google search bubble, have a VERY difficult time getting to Europe to find stuff. For Ebay I had to specifically search for Euro Ebay to get to look there and find a used one for testing purposes.

this guy's store has them for $430 US plus at least $90 shipping

http://stores.ebay.com/Parts-for-Aud...p2047675.l2563

So, don't anybody do anything JUST yet, I need to get the diaphragm out and compare for sure, then perhaps give one a go in my perfectly running car, to see if it functions. I might have to buy a new one, since this one is soaked in diesel fuel.

Audi AWA FSI high pressure fuel pump, from say 2002-2004 range or so.

brtw: I am already taking one apart, (had it sent from England) just trying to get the diaphragm out without destroying it. But, the more the merrier on this science project. We really need a source, and maybe people buying cheaper similar pumps and dissecting them to find the one that costs the least money when new.

Yes, dude this is one of them. I am totally "Jeally". I paid twice that for mine.

Again, that one is used, and has seen diesel fuel all it's life. The main reason to buy it is to dissect it and verify it's diaphragm is a fit. I guess you "could" try it in your pump. I am going to try to get that steel retainer ring out and make a few pictures to show how I did it once I get it done.

Can you research dealers or good parts sources for new ones? Right now it is looking like $1000 US, for two, shipped to the states.

BTW: from reading that BMW N73 document someone posted awhile ago, the diaphragm appears to be on the supply side, which means, only about 80 psi, and it's there to damp pulsation. Still not sure why it vents vapor? Is it gas-permeable?

Also, V12 had a question as to if there were supposed to be two diaphragms. My diesel pump expert guy who dissected one of my pumps found two layered together as well. If I manage to dissect mine without destroying something, I'll back that info up.

hmmm, great find, considering that Alfa condizioni is "Usato", and they want $499 E for it, too big a risk. It did not show up on the Bosch part interchange list. Might have the diaphragm, might not. But I like the way you are thinking.

But you're right, the VW/Audi pump itself will never bolt up to our cars. The mating surfaces and casting are different. Would be great to fully disassemble one and measure the spring pressures and such and see how much of it is identical.

Can we count on our European V12 brethren and sisters to please help us find brand-new-part sources for the VW and Audi pumps, please?

Folks we have a diaphragm!!!

Not one that is tested in a car, but it's the same part number and we have a source that costs less than replacing our pumps at $3600-$5000 a pair.

I took some time this morning to talk to Giles at Performance Diesel, who has been helping me with this, and for me to figure out how to get the steel retaining ring off, so I could remove the diaphragm and verify it fits into our pumps. It does!!! The Bosch interchange part list Giles had was correct. This means one can buy a new VW or Audi HPFP of the above mentioned part number series and dissect it and get a replacement diaphragm, when yours dies and leaks.

here's the YouTube video. There's also pictures with captions below:



The steel ring is not pressed in, it's just a very close fit. Make sure it's lubricated and you can pry one edge up at a time, and slip it out. Don't pry one side too long, or it will get cocked sideways and stuck. On my gas HPFP it was very dry and had been sitting for a year, so the steel ring was stuck. Some WD-40 (maybe I should have used gasoline, to not contaminate the pump) and a light tap on the ring in a few places, loosened it up. You could probably lift it out with a big magnet as well.






Now, you should be looking at this, The diaphragm ready to come out. On the newer Diesel pump it slipped right out--see the one sitting on the paper. It was well-lubricated. On my gas version, it was stuck and glued to the internal parts. Very dry. Since it was already dead, I destroyed it to get it out






The diaphragm on my old pump tore into two layers. That is why V12 thought he had two installed. It simply had delaminated. The second layer is the one that was almost glued inside the pump, it was so dried out. If you run into this, you might want to just use some gasoline to lubricate it. (being careful not to smoke while doing this job, of course ;-P)





Finally:
here's the Audi diaphragm fitting perfectly into my BMW HPFP. If this diaphragm were new, I would just bolt everything back up and try it. I guess you could even steal the rubber O-ring off the Audi pump as well.

Nice video. The instructions are also in TIS. Do you provide steps to repair if someone emails you?

Also, it looks like you replace the HPFP with a new or good one? We are tying to figure out how to repair a dead HPFP without buying a new one for $1800 US.

I did not understand the question. I'm from Czech, my English is not good ....... One of the two pumps was bad, so I began to explore and eventually figured out a way how it can be repaired. You no longer need to buy a new HPFP!!!

That is good you figured out how to repair a bad pump. Can you please tell us how?

You can always use google translate if you don't understand the English

I understood. The method took me a lot of time and nerves, but if you want, we can make a deal, you send me a bad pump, and I'll repair and send it back. In one day I repaired.

I'll take $ 300 for a complete inspection and repair of all what is needed to repair the pump and give a guarantee on the work.

It is a special membrane hidden under five tiered three screws which are other components of the pump.

I know, I show all that in my pictures too. I want to know where you find a NEW one when the old one is bad. Where do you buy it? Do you buy a new green one, or a good used one?
