Let's not go claiming it's only turbo charged DI cars that have this issue. The B7 RS4 is the first major case of carbon build up in DI engines. The Toyobaru is DI with port injection that's supposed to wash the intake valves, but that motor has had some cases of fuel starvation, so not all is right with that setup yet either. It will be interesting to see how the newer Audi engines do with their dual injection setup.
