DSG Repair

The DSG dual-clutch gearbox, available in 6-speed and 7-speed versions, is unlike a conventional automatic transmission.

Two independent gearboxes are connected under load to the engine in turn, depending on the current gear, via two drive shafts. An output shaft assigned to each gearbox applies the torque to the driven wheels via the differential gear. Clutches and gearboxes are operated hydraulically by the gearbox mechatronics (a combination of mechanics and electronics).

The electronic transmission control unit, sensors and hydraulic control unit form one compact unit. The control unit uses information such as engine speed, road speed, accelerator position and driving mode to select the optimum gear and to determine the ideal shift point. The control unit then implements the shift commands in a sequence of precisely co-ordinated actions.

Each change takes less than four-hundredths of a second. DSG can be used manually, via the Tiptronic gear lever or the optional paddle shift.

The clutches on these systems are nearly bullet proof and are rated by the manufacturers to last the life of the car. That being said the dual mass flywheel is an issue and will need changing, anytime from 60 to 100,000 miles. Anything less that 60,000 would require an investigation in to how the engine is running. Vibrations from a faulty dual mass flywheel are transferred to the gearbox, which can incur issues there as well.

Replacement of the dual mass flywheel is a straight forward job that any competent garage should be able to carry out, removal of the clutch requires special training and special tools. Once removed the clutch can not be refitted (dry clutch).

We at Care care Garage Services are always looking for different ways in which can improve our staff training and improve the services we can offer our customers. We are now taking bookings for DSG Repairs.
