My understanding from two techs, one a foreman, the S63 are pretty reliable, better built motors especially compared to the N63. Other than odd vacuum leaks, a pretty stout engine.

Big thing seems to be to manage the under hood temps better to provide longer life to the adjacent components near the turbo and downpipes.
