Will do the flaps too it’s a good call, anything else to check in respect of this one? I’d like to catalogue this together with other peoples FSI’s too (at different mileages) if they have an endoscope, sad I know but still, it interests me.It is very likely that the crud that builds up in the FSI's inlet comes from the EGR system, and not directly from combustion. If that's the case, then (endascopic) visual checks will have to be done direct on the flaps. Carbon on the cylinder head and piston crown may not be an accurate guide to the inlet manifold. None the less, it would be very interesting to see a piston crown at 80+K, or 150+K even.
