I noticed that I can smell the windshield washer fluid when the ac is turn on and while driving. I dont have this smell while driving the C and B Class. Is this normal?

 

I'm assuming that this is when you have actually used the washer fluid to clean the window? If so, I have that too. The intake to the ventilation system is right under the windshield so I try to put the system in recirculatation mode when I wash the windows.
