Thanks to JimmyBones, justincredible and the site I’ve concluded that the two HPFP’s need to be replaced. I found some interesting stuff regarding pricing on these between dealerships (got them for $100 under msrp), but needless to say I should have them next week.
I feel pretty confident doing this job myself and understand how to depressurize the system, etc. I do need to pick up a new torque wench and was checking out the manual recommended vag 1331 - looks pretty awesome with various attachments, etc.
Any words from the wise out there on doing this procedure? I’m planning on replacing the two pumps (07L127026AD) and accompanying o-rings. What about #8 in the part diagram? Should the roller-tappet/cam follower also be replaced? I know some inspect these for wear after removal, but I believe they’re < $100.
** I did notice that JHM offers some type of core refund with upgrading HPFP’s. After looking at the pump assembly I wondered why there is not a rebuild kit. Doing a bit of searching did turn up that some people have figured out a way to remove the two bolts in the top of the pump (see attached), but I didn’t go further. Has anyone cracked into any of audi’s hpfp’s to resurrect or upgrade? **
