Steering — general information

Steering consists of steering wheel, steering shaft, rack and pinion steering and tie rods (see illustration 13.0).



The force applied by the driver to the steering wheel is transmitted through the steering gear to the steering gear.

In the steering mechanism, the gear rack moves in accordance with the direction of rotation of the steering wheel to the left or to the right.

The tie rods transfer rotational force to the wheels through the tie rod ends and the steering knuckles.

The rack and pinion has no play and requires no maintenance. The exceptions are the sealing cuffs and anthers of ball bearings, the condition of which should be checked when servicing the car.

Golf/Touran vehicles are equipped with electromechanical power steering (servo control).

Power steering allows the driver to perform all the driving tasks with less effort. This is especially true when turning the wheels of a stationary car.


The force applied to the steering wheel supports the electric motor attached to the steering gear.

This electric motor drives an additional gear that is connected to the steering gear rack.

This process is coordinated by the control unit, which takes into account such parameters as the speed of movement, the angle of rotation, as well as the speed of rotation of the steering wheel by the driver.

In addition, on Golf/Touran vehicles, the power steering control unit automatically corrects the vehicle's straight-line driving in constant wind and sloping road surfaces.

Attention! Welding and straightening work on steering elements is prohibited. Always replace self-locking nuts and rusted bolts and nuts with new ones when carrying out repairs.

Attention! The specified tightening torques for threaded connections must be adhered to strictly. In case of insufficient experience in carrying out repairs, it is recommended to entrust it to an appropriate workshop.

The driver's airbag is mounted on the steering wheel.

The airbag is a folded bag that instantly fills with air in a frontal collision, thereby protecting the driver's torso and head from hitting the steering wheel.

With a sufficiently strong impact, the airbag control device ignites a small explosive charge and the gases resulting from the detonation of the charge inflate the airbag within a few milliseconds.

This time is enough to soften the impact on the steering wheel. The air cushion then collapses within a few seconds as the gases are expelled through the outlets.
