In Canada some 2006-2010 model year Audi A3 quattro vehicles and some 2008-2010 model year Audi TT/TT Roadster quattro vehicles. The affected A3 quattro vehicles were produced from September 30, 2005 through August 24, 2009, and the affected TT/TT Roadster quattro vehicles were produced from February 02, 2007 through August 26, 2009.

The closing force of an internal spring of the fuel tank ventilation valve is not adequate enough to hold the valve closed under extreme conditions. During dynamic driving maneuvers, liquid fuel may enter the fuel tank venting system and migrate into the evaporative system, saturating the carbon canister. Should this occur while driving, the vehicle may experience performance issues (i.e., vehicle jerking) and the malfunction indicator lamp (MIL) in the instrument cluster could illuminate. In rare cases, fuel could leak from the evaporative system leak detection pump filter. A fuel leak, in the presence of an ignition source, can lead to a vehicle fire.

Affected vehicles can continue to be driven as usual until the inspection/repair is conducted. If you can smell fuel in your vehicle, customers are advised to proceed immediately to the nearest authorized Audi dealer or qualified workshop if they believe that it is safe to do so in order to have the fuel system on the vehicle inspected.

There are approximately 2,660 affected vehicles in Canada. A customer notification is anticipated to begin in November 2009. Audi dealers will replace the fuel tank ventilation valve on the affected vehicles with an improved valve when this new valve becomes available.
