I am trying to figure out if my US 2007 E350 even has charcoal passenger compartment air filters INSIDE the car. I am aware of the passenger air filter under the hood.

Apparently some W211's had the passenger compartment filter under the hood AND two inside the passenger compartment under the panel under the glove box.

(Sometimes Mercedes-Benz makes me crazy).

I took the panel off under the glove box and did not find any compartment with "slide clips" that can be moved/removed to expose air filters.

Anyone know which year W211's had THREE passenger compartment air filters?
