Hi new to the forum wonder if anybody could help me as I'm having problems with my daughters fabia 2015 1.2 tsi running rough likes it's missing I've changed both map sensors ,plugs, coils, and still drives rough. On tick over it doesn't miss a beat, just while driving. When I scan it I gives me map inlet manifold fault but I've changed this sensor. Is it possible there could be a crack in the inlet manifold as its plastic. Any help would be appreciated 

 

Quite likely to be the turbo actuator or wastegate pivot, we have one in bits at the moment on a Leon.
