    From the link, there is this "Word in the 2.0 FSI forum is that the root cause is from the PCV valve sucking oil into the engine and collecting on hot intake valves. A PCV valve is supposed to just collect crankcase fumes but in the case of the FSI engines they suck in a bit of oil as well."  Seems like it is not normal carbon deposit.
