[s-cars] fuel vapor on warm days . . .

[Michael Wakefield]

I have the same problem on my S4. There is no apparent leakage at any 
of the fuel connections, including the recall ones, and there is "no" 
corrosion on the fuel line clips under the car. I suspect something to 
do with the canister in the passenger front fender.
