Do you experience "fogging" problem... sometimes when I drive I see some fogging spots... like a triangle on my windshield.. It appears externally. I've heard that many C230K owners have experienced it and that there are some solutions to get it "fixed"...

Actually, the fogging they are talking about is a chemical fog on the inside. It is caused by the outgassing of plastics. Almost all cars do this to some extent. The other kind of triangular fogging on the exterior and often interior, is caused by the triangular vent being open when the air conditioning is operating in very humid conditions. Try closing the vent by rotating the control wheel until no blue marking are visible. Sometimes this helps reduce the chemical fog.

YEs
IT's done by the triangular vent in the front

I see there's no use for it

so I close it at all times

ALso

it's really cool watching the fog dissappear in a manner of seconds when you defrost

When I close that blue wheel i get a whislting sound. It is very annoying. Does anybody else have that problem.

Give it an extra push. There is a slight detent to the open/close wheels. If they are not lightly forced closed, there is a whistling sound.
