Audi (and others, I believe) have noticed some issues with direct injection. Without fueling going over the valves, nothing is "washing" them. Some of the Audi FSI (direct inj) motors are having valve issue. The build up is likely realed to the PCV, the EPA requires the motors digest the crankcase vapors. So I am not too excited to get a direct inject motor until these issues are resolved....be it valve coatings, secondary injectors in the intake, "scheduled" seafoam treatments....something.
