interesting reading here:
dweisel's HPFP Analogy of a Failure - VW TDI forum and Audi TDI forum - myturbodiesel.com
Cliff notes:
design flaws and/or bad fuel lead to HPFP piston bore scoring (lubrication issue) and aluminum shower for the system also making the cam/cam follower falsely appear to have been the start of the issue.
Will try to find more.
