In fact in my
MCS at speeds over 160 km/h there is a constant whistling noise which has nothing to do with the wipers (even if I move them the sound is there). I have found out from some other guys here in Greece who have had the same issue that the problem was solved after removing and glueing back the rubber thing that sits between the windscreen and the roof. I am planning to take a ride to my dealer from September on and I will let you know about the results.
