Since I am now intensively concerned with the whole topic of RPF, but unfortunately only have the X20DTH as Euro2 engine, I am interested in how I get the engine on D3. I have read in the TIS that this conversion is possible. Definitely I know that the metal AGR has to be replaced for a plastic one, because the plastic AGR has a faster response time. What else needs to be changed to get the engine on D3 and thus on a green badge?
