Activated Charcoal Filter (ACF)

W220 W220 Replacing ACF Activated Charcoal Filter DIY

Tip: The hardest part about getting out the charcoal filters was the dexterity required. Had to get under the dash. Removed a few screws 
 on a flat plastic panel and then had to gently pull it out. There are overlapping plastic flaps that only come apart by gently manipulating. 
 Once you get this off, there are two nifty plastic hinged doors that swing open and all you do is slide out filters, straight down towards the floor.

NOTE: Activated charcoal filters must not be cleaned but should always be replaced. 

• Undo One Phillips screw and two 8mm screws. Remove right cover below instrument panel. I didn’t have to remove knee protection (3) as it will bend

out of the way to remove the canisters.

• Pull back right front floor covering
• Move locking slide (2) in the direction of the arrow and remove cover (1)
• Remove both activated charcoal filters (3) downwards out of the AC housing
• Install in the reverse order.
