I don't want DI unless they figure out how to keep the valves clean. The Audi and BMW DI engines get caked with oil and carbon junk on the valves, a big problem that they fail to address properly. That's why I won't buy one. Go ask the rs4 and S5 guys about their 70k cars with carbon junked valves. Needs to be done every 15k miles or so for cleaning. No thanks. Port injection works just fine.
