I agree, they really need to at least acknowledge the existence of this issue. Sure, it may be an "infrequent" occurrence--1%, 2%, whatever; that's an acceptable failure rate for a power window regulator, maybe. Also, it's worth noting the inconsistencies in responses (from differerent dealers, regional reps, corporate, etc.) to the same question. I emailed "VW Cares" and asked explicitly if the hpfp was covered under the powertrain warranty, and if so, if it failed, was associated damage covered. The response I got was "The HPFP is considered part of the powertrain and falls under that warranty, and any collateral damage would be covered if it failed."
Better, but still not good enough--most of us bought into these cars to keep them a long time, or at least with the intent of a good resale value if not. If you can expect an $8 - $10K repair every 36 - 60K miles, what the hell good is it?
I really wish I had stumbled upon this forum before buying the car; I may have done so anyways, but at least I would have made an informed decision.
(rant ended; we now return to your scheduled programming)

btw it could be argued that the HPFP *is* lubricated by oil--i.e., diesel.
