[s-cars] Gas smell when hard on throttle

[Tom Green]

Dealer or worldimpex.com or similar online source that deals in some  
genuine audi parts as well as OEM
replacements.  It's one of the check valves (bleeder valves) that  
control fumes to the charcoal canister.
The parts in this system are typically outrageous in price  
considering the minimal impact on emissions this
little system can have.

It would take some fuel resistant epoxy or the like to repair the  
valve, and if it doesn't operate you may still
have the fumes.  I assume the missing air-box was removed to access  
the area and future work here will
require removing it again each time.  You should consider any fuel  
fumes you can smell as being concentrated
enough to be dangerous, since you generally don't have any other  
information to evaluate.
