The recall applies to 2010-2012 Audi A3, 2010-2012 Volkswagen Golf, 2009-2012 Volkswagen Jetta and 2009-2012 Jetta Sportwagen vehicles equipped with the Volkswagen Group’s 2.0-litre TDI diesel engine.

A total of 168,275 vehicles are affected by the recall, including 161,144 Volkswagens and 7131 Audis.

CarAdvice has contacted Volkswagen and Audi Australia, who are investigating the matter to see whether the diesel engine defect also applies to vehicles sold in Australia. We will update the story when we hear more.

The official recall notice published on the National Highway Traffic Safety Administration explains the engine’s fuel injection pulses could coincide with the natural frequency of the injector line, producing a resonance that creates additional stress in the fuel line.

“Due to the resonance condition, injector line number two could develop small cracks which could lead to fuel leakage. Leaking fuel in the presence of an ignition source may lead to a fire.“Volkswagen will install an improved fuel injector line for the number two cylinder and will install vibration dampers on all of the injector lines.”

Volkswagen and Audi are contacting all owners of affected vehicles in the US, with the recall repairs to commence in November.

If Australian vehicles are affected, a local recall could be wide-ranging. Volkswagen Group vehicles sold in Australia equipped with the 2.0 TDI engine include the Audi A3 and A4, Volkswagen Golf, Golf Wagon, Jetta, Tiguan, Passat, Passat CC, Eos, Amarok, Caddy and Multivan, and Skoda Octavia and Superb.

At this stage, there is no Australian recall for any of the cars listed above. Stay tuned for updates.
