Hi there,
Does anybody know where the charcoal canister is located in a
1994 S320? Thank You.

Here is the PIC for ref

Thanks for the reply Bluesky . I've checked every wheel well but could not find the canister . I disconnected a hose from the (MOT) valve and blew into it which I think leads to the canister but the hose leads all the way back to the fuel tank .Could it be around the fuel tank ? And if it is how does it look like ?Thanks again .

Typically Mercedes "hid" the canister behind the plastic fender liner, so it's not actually visible from the wheel well or the engine bay. I belive the liner has to be removed to access the canisters.

Could not attach some more infor for you. They limit they space. If you don't mine give me your email address. I would send you some more PIC for reference and infor of diference model you need to do your work.
