DSG dual clutch gearbox
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 gear train halves 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.
Function
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 gear train halves, the engine power is always
connected to one gear train half when driving. Before a gear change, the next higher or lower gear
is already 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. Thanks to its efficiency, low
weight and intelligent control system, the DSG dual clutch system usually enables fuel
consumption 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 dual clutch gearbox DSG;
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 ⇒ Troubleshooting. If this happens, have the system checked as
soon as possible by a qualified workshop.

Serious damage to the clutch and gearbox can occur if the gear stick on the manual
gearbox is shifted to too low a gear when travelling at high speeds or at high revs. This
also applies if the clutch remains depressed and the gears do not engage.
NOTICE
Please note the following to help avoid damage and premature wear:
•Do not rest your hand on the gear lever when driving. The pressure from your hand is
passed onto the selector forks in the gearbox.
•Ensure that the vehicle has come to a full stop before engaging reverse gear.
•Always fully depress the clutch pedal when changing gear.
•Do not hold the vehicle by riding the clutch on a hill with the engine running.

If the selector lever is moved accidentally to N when driving, take your foot off the
accelerator. Wait for the engine revs in the neutral position before selecting a position again.
Changing gear using Tiptronic
Tiptronic allows the gears to be shifted
up and down manually with a DSG
dual clutch gearbox.

hand drive vehicles.

The gear that is currently selected will be maintained when the Tiptronic programme is selected.
This remains the case as long as the system does not automatically carry out a change of gear due
to the current driving situation.
Operating Tiptronic with the selector lever
•Push the selector lever from position D/S to the right into the Tiptronic gate.
Selecting the wrong position can cause you to lose control of the vehicle, which can lead
to accidents and serious injuries.
•Never depress the accelerator pedal when selecting a position.
•When the engine is running, the vehicle starts moving as soon as a selector lever
position is engaged and the brake pedal is released.
•Never switch to reverse or selector lever position P while the vehicle is moving.
WARNING
Unintentional vehicle movements can cause serious injury.
•The driver must never leave the driver seat when the engine is running and a position
has been selected. If you have to leave the vehicle while the engine is running, always
switch on the electronic parking brake and move the selector lever to position P.
•If the engine is running and the selector lever is in position D/S or R, the vehicle must
be held on the foot brake. The vehicle will creep forward even when the engine is
idling, as power transmission is even then not fully interrupted.
•Never select reverse gear or selector lever position P when the vehicle is in motion.
•Never leave the vehicle in selector lever position N. The vehicle will roll downhill
irrespective of whether or not the engine is running.
WARNING
If the electronic parking brake is not switched on when the vehicle is stationary and the
brake pedal is released when the selector lever is in position P, the vehicle may move a
few centimetres forwards or backwards.

Deactivating Car-Net services

deactivated.
First read and observe the introductoryinformation and safety warnings⇒
Introduction
If you sell the vehicle or lend it for a longer period, inform the user about the deactivated services or
deactivated control unit.
If your vehicle is already equipped with the legally required emergency call function eCall, this
function will not be affected by the deactivation.
Temporary deactivation
If your vehicle is in a workshop, you may find that the service technicians have deactivated
individual or all services for the duration of the workshop visit. The services will be available again
once the work is complete. Please contact your workshop if necessary. Individual Volkswagen Car-
Net services can be deactivated manually via the Infotainment system. The services can then be
run again when the deactivation is cancelled in the Infotainment system. Deactivated services are
marked in the Car-Net portal on the start page with a corresponding indication.
Permanent deactivation
In order to permanently deactivate Car-Net functions in vehicles with the Security & Service or
e-Remote packages, the online connectivity unit must be deactivated by a qualified workshop at
your request.
Once the on-board connectivity unit has been deactivated, the workshop will attach a sticker
⇒ Fig. 180 to your vehicle (e.g. on the roof console). The sticker shows that neither the
Volkswagen emergency call service nor the automatic accident notification will work. All other
e-Remote and Security & Service services will also be deactivated.
Interferences
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Even when the above-mentioned requirements for using the services are met, the functionality of
the Car-Net services can be impaired or interrupted due to factors that lie outside the control of
Volkswagen AG. Such factors include in particular:
•Maintenance, repairs, software updates and technical changes to your service provider’s
telecommunication systems, satellites, servers and databases.
•The telecommunications provider has changed the mobile telecommunication standard for
transferring mobile data, e.g. from UMTS to EDGE or GPRS
•An existing mobile telecommunications standard has been shut down by the
telecommunications provider.
•Impairment or interruption to mobile and GPS reception, e.g. due to high speeds, weather,
landscape, interfering devices or intensive use of the mobile network in the relevant cells.
•The availability, completeness or correctness of information provided by third parties, e.g.
maps.
•Countries where Volkswagen Car-Net services are not available.

Introduction
Data transmission
The data for using the Volkswagen Car-Net Guide & Inform services are transferred via your mobile
device with data option or a SIM card with data option. For some services, your mobile device or
your SIM card needs to support a specific data connection type, e.g. rSAP.
Data transmission for running the Volkswagen Car-Net e-Remote and Security & Service services
is performed using a factory-fitted control unit with an integrated SIM card with data option.
Availability
Volkswagen Car-Net services can be subject to a limited period or changed, set, deactivated,
reactivated and expanded without prior notice.
Some Volkswagen Car-Net services contain external information that originates from third parties
(e.g. maps). Volkswagen AG is not responsible for external information being correct, up-to-date
and complete, or for any infringement of third-party rights.
