2009 Audi TT recalls

2 NHTSA recall campaigns list this model year.

  1. NHTSA 09V377000Sep 30, 2009Fuel System10,200 vehicles

    Fuel system, gasoline:storage:tank assembly

    Volkswagen is recalling certain model year 2006 through 2010 audi a3, tt, and tt roadster passenger vehicles manufactured between september 29, 2005 and 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 driving conditions possibly allowing fuel to leak.

    Risk: In the presence of an ignition source, a vehicle fire could occur.

    Remedy: Volkswagen will notify owners and audi dealers will replace the fuel tank ventilation valve with an improved valve free of charge. The safety recall began on november 16, 2009. Owners may contact audi at 1-800-253-2834.

  2. NHTSA 09V333000Aug 20, 2009Transmission & Powertrain16,000 vehicles

    Power train:automatic transmission

    Volkswagen is recalling certain model year 2009 and 2010 passenger cars manufactured between september 2008 and august 2009. The wiring harness of a temperature sensor in the direct shift gearbox (dsg) may have connector wires that were insufficiently crimped. With insufficiently crimped connector wires, a temperature sensor has the potential to falsely detect a high gearbox oil temperature, causing the transmission to abruptly shift to neutral. If this happens, the selector lever position indicator within the instrument panel will flash. In addition, the "depress brake pedal" indicator light will be illuminated, alerting the driver to apply the brakes.

    Risk: The abrupt shift to neutral could lead to a crash without warning.

    Remedy: Volkswagen will reprogram the transmission control module with updated software free of charge. The recall began on october 20, 2009. Owners may contact volkswagen at 1-800-822-8987.
