Charcoal filter???
I have a 300CE with M103. I just swapped my cylinder head with a Brabus one that I got from one of the members here. After installation, I sent my car to a Mercedes Specialist to get the engine tuned up. The Mercedes Specialisit told me I needed to replace the "Charcoal Filter" to smooth out the idling. Any truth in this?
BTW, where's the Charcoal Filter located? Rgds |

Charcoal canister? Is it causing a vacuum leak?

What the hell? How much does it cost? I've never hear of this....not that I've heard of everything by any means.

Charcoal filter
I do not know exactly what system Mercedes uses.
If it is similar to the 70s Saab 99/900; then a charcoal canister is part of the evaporative emission control system. The charcoal is a temp storage device for gas tank fumes; after a period of time the coals become saturated and must be changed. With the Saab, I opened up the container(it was not meant to be opened, slows me down a little), dumped the old stuff and renewed using charcoal from a per store (Hertz ? brand).. cost about one dollar. Why did I not use charcoal briquettes ?? Good question.. I was looking for a source of charcoal where the cost was 25 cents per pound or less.. My philosophy is if something, anything can be completely fixed for "pennies", then go for it.. My labor is free now; when it was not, it was still the thing to do.A little work never hurt anyone.

As asked for above, about all the charcoal canister can do wrong is be a vacuum leak. A defective tank system can cause fuel to pass through the cannister, but that wouldn't be the cannisters fault.
For diagnostic purposes the thing should be isolated to prove that the idle improves. Sounds like guessing to me.
