Hi, I just bought a used w211 2004 e320 for my wife and it says that I need to change the charcoal/ pollen filters. Are there really 3 filters to change? (2 charcoal and 1 pollen) Can you please help me to find them and replace them? Thank you.

Looks like 3 of them.

#540 accessed from the engine compartment and #310 from the passenger side foot well.

Next thing to buy is the W211 Service DVD which contains all the maintenance/repair procedures you'll need.

At your dealer or at 800.for.merc
