    Check your pipe to the charcoal canister & the spill off pipe from fuel rail to inlet manifold.

    My pipe to the charcoal canister spilt & caused a smell of petrol, replaced it with silcone pipe & i also replaced the spill off pipe as this was cracked on the up bend to the inlet manifold.

    I had this on my s3 it turned out to be the fuel filter. It had a tiney hole not visable to the eye. I found out because after a fews days like it fuel started pi**ing out of it.

    Have a look around the fuel cap to see if there are any drops of fuel there. I had an issue with a gravity valve in the fuel tank meaning that pressure built up inside the tank and was pissing fuel out whilst driving. To check if you have a faulty valve, start the engine and then go round the side to undo the filler cap if you feel pressure building behind when you pull it off or fuel pisses out - bobs your uncle.

    Oh it is a 4.00 part but you need to drop the tank to change it and about 4 hours to complete

    Had the same issue with smell, really noticed it when the blowers were on. Turned out the plastic hose on the carbon canister had completly snapped off at the connector, stupid Audi plastic
    Anyway short story long I temp fixed it with a rubber connector and the smell seems to have disappeared. Really must invest in some silicone tubes and strip the lot out. I have pics but not too sure how to uplaod them..

    think i figured it out, its only after filling up i get the smell. No doubt getting some around the flap, dosent happen all the time which would explain why its sporadic
