Function of the DSG® dual clutch gearbox

Description

The vehicle is equipped with a DSG dual clutch gearbox.

The DSG^®dual clutch gearbox is a gearbox which uses dual clutch technology to change gear automatically. It uses a

dual clutch and two independent gearboxes to enable very fast gear changes with no loss of torque. The DSG^®dual

clutch gearbox thus combines the performance and economy of a manual gearbox with the comfort and convenience

of a conventional automatic transmission.

How the system works

When driving, engine power is transferred to the drive axle via the gearbox. In order to change gears, the power

transmission between the engine and the gearbox has to be interrupted. This is what the clutch is for.

With the DSG^®dual clutch system with its two complementary gearboxes, one gearbox is always connected under

load to the engine. Before a gear shift, another gear is always preselected in the load-free second gear train half. The

clutch on the non-driven gear is closed and the other is opened at the same time. This is what makes very fast gear

changes possible.

Thanks to its design, the DSG^®dual clutch gearbox is more efficient than an automatic gearbox. Whereas in an

automatic gearbox the torque converter is constantly in use, in the DSG^®dual clutch system the clutch can be opened

at idling speed, thus saving fuel. With its efficiency, low weight and intelligent control system, the DSG^®dual clutch

gearbox usually enables fuel consumption that is equal to or lower than a manual gearbox.

However, just like the manual gearbox, the clutch in the DSG dual clutch gearbox is subject to wear. Regular

maintenance is necessary depending on the type of DSG^®dual clutch gearbox; further information (→ Scope of

service). In the event of a fault in one gear train half, the DSG dual clutch gearbox also allows one gear train half to

be deactivated and the journey to be continued using the other gear train half (→ Automatic gearbox). If this

happens, have the system checked as soon as possible by a suitably qualified workshop.

Dual clutch gearbox DSG®: Selecting a position

Fig. 1 Selector lever for the dual clutch gearbox(DSG) with

button for parking lock.

The selected position is shown on the instrument cluster display and on the upper part of the centre console→ Fig. 1

when the ignition is switched on.

The gear shift pattern is shown on the instrument cluster display when the brake is applied or when a position is

engaged.

– Parking lock

The drive wheels are blocked. May only be selected when the vehicle is stationary.

To engage the parking lock, press theP button → Fig. 1

If the engine is switched off in gear selector positionD/S or R, the gearbox automatically engages the parking lockP

to prevent the vehicle from rolling away.

If the engine is switched off in positionN, the gearbox remains in neutral positionN for around 30 minutes and only

then engages the parking lock P (car wash function)(→ Switching off the engine).

– Reverse gear

Reverse gear is selected. May only be selected when the vehicle is stationary.

– Neutral

The gearbox is in the neutral position. No force is transmitted to the wheels and the braking effect of the engine is

not available.

– Standard forward driving position

Position : normal programme.

All forward gears are shifted up and down automatically. The timing of the gear shift is determined by the engine

load, your individual driving style and the speed of the vehicle.

Position : sport programme.

The forward gears are automatically changed up later and down earlier than in selector lever positionD. This exploits

the engine’s full power reserves. The timing of the gear shift is determined by the engine load, your individual driving

style and the speed of the vehicle.
