Check of level of liquid of system of hydrostrengthening of a wheel

1. Periodically check liquid level in system of hydrostrengthening of a wheel in order to avoid emergence of problems with management of the car, such, as damage of the steering pump. Act as follows.


Do not hold a steering wheel turned against the stop in this or that party more than five seconds. It can put out of action the steering pump.

2. The tank of system of hydrostrengthening of a wheel is located in an impellent compartment and has an unscrewing cover with built in in it measuring the shchupy.
3. Park the car on an equal platform and cock the parking brake.

Level of oil can be checked in a cold or heated-up condition (since +50°С). Here check in a cold condition is described. Pay attention to the remarks provided in the end of the Section if level of oil has to be checked in a heated-up condition.
4. The car should not be heated-up, the engine should not work. Forward wheels should stand directly.
5. Unscrew by means of a screw-driver a tank stopper (the shooter on an accompanying illustration). For this purpose insert a screw-driver core into a stopper groove.
6. Wipe a pure rag the level index under a cover.
7. Manually screw and again unscrew a stopper. Oil level on the index should be in a range of 2 mm above or MIN markings are lower.


As a rule, level of oil should not go down. If level of oil decreases, it is necessary to eliminate a leakage on HUNDRED AUDIS. If level of oil lies above the specified range, oil is necessary for pumping out.

8. Oil is added surely only new as even insignificant pollution can lead to hydrosystem failures.
9. Wrap a stopper by means of a screw-driver.

The remark on check on the engine, heated-up to working temperature:

Warm up the car, having executed a trial trip. Oil should get warm to temperature near +50°С. Check oil level on the working engine. Thus forward wheels should stand directly. Oil level at the screwed cover should be between MIN and MAX marks on the other side of the index.
