I treat them all as requiring tear-down inspection.

Too few mechanics, dealers included, get it right.

If not a dealer, chances are high that a rebuilt pump was used. One rebuilt pump failure mode is impeller sliding slightly toward block, acting like a machine tool on it. (New-casting, plastic impeller "Laso" replacement pump is a recent development by enthusiasts to combat this issue -- It wasn't around 8 years ago). Porsche new pump was the better option back then, and still is, but is cost prohibitive now for most of us.



(Most uber-enthusiasts will say 8 years is too long on a rubber timing belt. Assuming thats a legitimate fear, you sure don't want a tracking issue or sharply worn gear to be hidden under those covers at the same time).

I'd also insist on new fuel lines!


Further, I'd check crankshaft endplay on a PPI if automatic car. Crucial check for automatic S4 & GTS. Thrust bearing failure is terminal and the 928 has a design flaw that can silently increase preload force on the crankshaft, resulting in contact wear of thrust bearing.
