Volkswagen Group of America is recalling about 43,000 VW and 10,000 Audi models to repair faulty Direct Shift Gearboxes (DSG).

The 2007-2009 models are the Volkswagen R32, Jetta, Jetta SportWagen, GTI, Eos, Audi A3 and TT.

VW said some customers had reported “transmission performance issues under certain driving conditions” due to a faulty component inside the Mechatronic unit.

The US unit will repair or replace components at no cost to owners or reimburse those who have had the fault repaired at their own expense.

VWGoA said the transmission recall was not related to an announcement on 20 August that it was replacing a faulty temperature sensor in a separate and smaller group of vehicles. This addresses a potential for the sensor to cause the transmission to shift into neutral while the vehicle is being driven.

VW said it would extend new vehicle limited warranty to cover affected DSG transmissions for 10 years or 100,000-miles.
