What are the defects?
Due to electrolysis in the gearbox, the sulphur constituents in the synthetic oil can separate off. These accumulations settle between the conductor paths of the electronics in the form of conductive particles and can therefore cause an electrical short circuit and the gearbox fuse could blow. Should this happen, the clutch will fully open due to power supply failure, causing the vehicle to roll to a stop if in motion.
What are the hazards?
In the majority of cases, the fault occurs when the engine is started with the vehicle stationary. If the fuse blows while the vehicle is in motion, however, a sudden loss of power at the wheels could in certain circumstances occur while the vehicle is being driven. This may pose a hazard to the vehicle occupants and other road users. All other functions of the vehicle (steering, braking, etc.) remain fully active.
What should consumers do?
A letter is being sent to affected owners of the vehicles. For further information, customers can contact their local Volkswagen Authorised Service Centre or contact Volkswagen Customer care on 1800 607 822
