NHTSA lists 2 fuel-system recalls for the 2010 Audi A3, out of 5 recalls in total. A recall applies only to the vehicles named in it, so check your VIN.
Volkswagen is recalling certain model 2009-2012 jetta and jetta sportwagen vehicles, manufactured from may 2008 through september 2011, model year 2010-2012 volkswagen golf vehicles, manufactured from may 2009 through september 2011, and model year 2010-2012 audi a3 vehicles, manufactured from september 2009 through september 2011, that are equipped with a 2.0l tdi common rail diesel engine/clean diesel engine. The fuel injection pulses could coincide with the natural frequency of the injector line #2, in specific load and rpm conditions. This resonance creates additional stress in the fuel line.
Risk and remedy
Risk: Due to the resonance condition, injector line number 2 could develop small cracks which could lead to fuel leakage. Leaking fuel in the presence of an ignition source, may lead to a fire.
Remedy: Volkswagen will install an improved fuel injector line for the number 2 cylinder on certain vehicles and will install vibration dampers on all of the injector lines. Volkswagen and audi will notify owners to have the vehicles repaired free of charge. The safety recall is expected to begin during november 2011. Owners may contact volkswagen at 1-800-822-8987.
