All I was asking was if anyone knew if the new hpfp/fuel system was different besides just the injectors. I didn't want to completely de-rail the thread, but since it already is, here goes.
Bosch designed the hpfp for euro spec diesel, and recommend using fuel with an atsm spec of 460 microns. What's available in the US is 520 microns. They recognize that the pump could self-destruct with >460 microns. Why not just add a little B2 or stanadyne? VW says in writing not to do that, and it could possibly effect the warranty. If you guys do some research, you'll find most people have gone as far as keeping all fuel receipts and having samples of their fuel tank and local gas station tested in their fight against trigger happy techs and reps who automatically assume an owner put some gas (petrol) in their tank. Why don't more people boycott the tdi? Because we don't have any other great options at this point; hybrids just aren't good enough yet.
I'm happy for you guys in EU and other parts of the world who don't have this issue b/c your fuel provides the recommended lubricity, but here in the US it's a real concern. I have tremendous hopes that the VII US-spec diesel will have solved this issue.
