Audi FSI Engine Carbon Build-up Thread for A5/S5

This thread serves as an index for carbon build-up related threads within the B8 A5/S5 sub-section. There is a "megathread" located in the Drivetrain section for an index of all models located here. Feel free to PM me any additions (internal or not). I can also index any model specific information one might have.

I've tried to tag content as much as possible. With either PICS where there is photographic evidence or CONCERN where there is discussion surrounding concern of the issue.

A5/S5 specific threads:
S5 FSI engines doomed due to intake manifold carbon build-up ? CONCERN
