Nothing new here. Where this discussion should end up is how do you clean valve tops in a direct injected engine. No fuel or detergent outside of the combustion chamber- probably be some kind of water injection treatment that isn't too detrimental to catalysts or something. Audi's have had this problem for some time on their DI 2.0 liters.

I have seen Audi owners install meth injection. I was suprised how dirty the DI engines got.
