[s-cars] Emission Canister

[Alvin Labonite]

S-folks:

How likely is the evaporative canister to go bad? Any experiences with them
going bad? I get a fuel odor after parking the car and it seems to be coming
from the pass front wheel well and or under the car. No smell from the
engine compartment that I can tell. Local Audi shop pressure tested the
system and found no leaks.

Pic #1 is what i'm talking about.
