The hydraulic system provides the power needed to support the driver's efforts. This system consists of a pump driven by the engine poly V-belt, a fluid reservoir and hydraulic lines.
The principle of operation of the system: The pump sucks oil from the tank and delivers it under high pressure to the valve body, which is located in the steering mechanism. Depending on the turn of the steering wheel, oil is supplied to the left or right side of the working cylinder. There, the oil presses on the rack and pinion piston and thus keeps the steering gear moving.
If we ignore some of the adjustment and maintenance work, we can say that it is impossible to independently maintain the power steering, especially its repair. Most often you have to check the oil level in the tank.
Power steering gear: 1 - tie rod end, 2 - hex nut 40 Nm. 3 - band clamp (be sure to replace), 4 - cuff (after setting the convergence, the cuff should not be twisted), 5 - o-ring of circular cross-section (be sure to replace), 6 - power steering (lubricate the gear rack with grease for steering gears A0F 000 05), 7 - hose clamp (be sure to replace), 8 - transverse steering rod.
Do-it-yourself steering repair?
Power steering repair is a workshop job. The workshops have special test devices that allow you to interrogate the codes of the control device, and the staff has the appropriate knowledge. This is the only way to avoid malfunctions of electronic components and the damage that can be caused by these malfunctions, as well as high repair costs. Therefore, power steering repairs should be left to a workshop. With unskilled repairs, the steering may fail.
Airbag: repair only in the workshop
Strict rules must be observed even when transporting and storing airbags, the same applies to the workplaces intended for dismantling and installing the airbag module. In addition, a gas generator that instantly inflates an airbag in the event of a collision is subject to the Explosives Act. Therefore, the manufacturer only allows trained personnel to install airbags in series; qualified specialists carry out this work in workshops. For this reason, we strongly recommend that you refrain from any work related to the steering wheel with airbag, as well as the airbag for the front passenger. This also applies to cosmetic repairs, when, for example, the steering wheel is additionally equipped with a wooden or leather lining. Airbags should only be handled by workshops.
