[s-cars] Emission Cannister

[Tom Green]

The system just temporarily holds hydrocarbons in the canister, then  
pulls them
back out and burns them in the engine, so I doubt it is a faulty  
canister unless
it is damaged.

Remove the airbox and inspect the valve, item 18 in your  
illustration.  The
mystery fumes could be a broken valve.  I repaired mine with JB  
weld.  If
you are saying the local Audi shop pressure tested the system  
illustrated,
then they might as well pressure test your wallet.  Hmmm....., I  
guess they did.
:-)   It captures fumes from the tank as well as the engine so  
functionally
testing the entire system installed is difficult.
