I'm getting ready to do a 90,000 mile service, and in my maintenance booklet it says under the heading "Engine Compartment" to "replace activated charcoal filter" Every 75000 miles/120000km/4 years.

Since I am almost certain that the cabin filter has no charcoal filter, I must assume that this refers to the emission control charcoal filter.

Has anyone replaced the charcoal canister as a part of preventive maintenance? Is theis the actual part that the manual is referring to?

Thanks,

Anyone? Anyone ever replace the charcoal canister on a E420 / 400E for maintenance purposes?

Benz has 3 types of cabin filter.

1) A Dust Filter
2) A Combination Filter (dust filter with a bit of carbon filter capabilities and finer filter material.
3) A Active Charcol Filter (fitted with a dust filter also in W211)

The active filter was an option on earlier cars and on the low end of current models.

If you don't have a button for it on ths A/C control panel then you don't have it, just use a combination filter.
