Question 05 C320 coupe. Dealer says charcoal canister is clogged & wants $950 to fix. Options?

I cant fuel my car more than 1 gallon without taking a break. I took it to the dealer, they diagnosed it as a clogged charcoal canister and says repair will cost around $950

Can someone point me towards the right direction? Called a few autoparts stores they claim thats a "dealer only" part. There has to be another way.. I'm open to any options!



EDIT: I was told by the dealer the vehicle needs a new charcoal canister which is needed for the evaporative system with the fuel tank. The canister would need a new valve and wiring harness due to the fact that the canister is an updated part.
203-470-03-59 ACTIVATED
000-470-71-93 VALVE
211-440-01-34 CABLE HAR

EDIT 2: I think I found the original part:
Mercedes Benz - C320 - Purge Valve - Vapor canister - 0004701593
Can any one confirm? I'm assuming since its unmodified I wouldn't need the other two items?

You can try posting this on the w203 forum. I did not find any specific posts that would help you.
The charcoal filter will be in line with the fuel filler opening. If you sign up for "EPC online", you pull up a diagram that will show you the location. The epc is free in the US. I looked on autohausaz for the part you need but could not find it. Getting the part number from the epc will help with that though. You can search for the part number itself-you can just google it. You could always just order it from the dealership's parts dept. I am not sure how comfortable you are changing it yourself.
Here is a write up on changing the canister on a w210. Not the same model as your car but it should give you an idea of how it is done.


Alternatively you can find a indy mercedes shop and get a quote from them.

Good luck. Hope you get your mercedes fixed and running properly soon.
