I love it too, but the early implementations are really prone to carbon buildup.
My 12 A4 is a perfect example. At 70k miles, I had to pull the intake and decoke the exhaust ports, valves/stems and guides. The amount of carbon buildup was shocking. For 13+ VW/Audi installed a second injector to keep the valves clean.
