Does anyone know if the Octy 3 VRS TSi has any new features to help reduce the inlet carbon build up that plagues the earlier version on this engine?   I read somewhere that the Golf  7 GTi  has extra injectors into the manifold (ie on top of DI) to meet EU emissions and that as a side effect this means the mainfold and backs of valves actually get washed by petrol a bit reducing the build up.   Any info if the Octavia 3 Petrol VRS is the same and views on effectiveness?   Obviously maybe
