Laguna Hills, CA – December 24, 2018 – Volkswagen Group of America, Inc. (Volkswagen) is recalling certain 2018 Audi TT Roadster, TT Coupe, A3 Sedan and A3 Cabriolet vehicles due to a fault in the fuel line connection. The potential number of units affected is 1,104.
According to the NHTSA Recall Safety Report, recalled vehicles were manufactured between March 9, 2018 and April 13, 2018 and have received fuel lines built in a specific time period where dimensional deviations in production may have occurred.
These vehicles are also equipped with a guiding sleeve for the assembly of the fuel line to the quick connector. Due to the dimensional deviations at the fuel line, the guiding sleeve may not be leak-proof at the connection point.
The underhood fuel supply hose quick connector may also not be securely attached to the fuel supply line, creating a risk that the fuel line may open at the quick connector, which may cause fuel to leak into the engine compartment.
Leaking fuel in the presence of an ignition source may result in a fire. The customer may recognize a fuel odor in the vehicle prior to fuel igniting.
