I personally wouldn't go to Mercedes for anything except battery certification. (free) once a year. I do my wiper blades, cabin air filter, and tires myself.
The car needs "Mercedes" summer fit/winter fit windshield washer fluids --
other colors throw off the sensor (Makes the car think the washer fluid is empty)
So I buy Mercedes "Summer Fit" / "Winter-Fit" concentrate on Amazon/eBay -- mix as instructed with water.
Cabin air filter takes 2 minutes, no tools needed -- email me for pictures. (Buy on Amazon or eBay)
