Replenishment of a tank of a washer of glasses

Continuous check

Suspension from exhaust gases, evaporations of oil and silicone from conditioning agents behind a varnish are constantly postponed on glasses. In a warm season therefore it is recommended to add detergent in water; nonfreezing liquid in the winter is necessary.

After removal of a plastic cover of a water-proof casing there are available three fixing screws (1, 2 and 3) screen wiper levers.

On an illustration on the right the engine of a screen wiper (1) is removed from the lever. On a drive (2) carving openings of fixing screws (arrow) are visible. As there should be a crank of a drive (3) at installation, shows drawing: shift from a parallel on
a= 6 ° to an average axis of the engine.


  1. The bulk branch pipe for water is at the left in a motor compartment near a broad tank of cooling liquid. The tank includes about 4 l on the models which have not been equipped with system of washing of headlights if the car is equipped with similar system, the tank contains about 6,5 l.
  2. At first it is necessary to pour in detergent, only then water in order that these liquids well mixed up in a tank.
  3. If the car is not equipped with system of heating of vpryskny nozzles, they can freeze in hard frosts.
  4. For prevention of it the increased concentration of nonfreezing liquid is recommended. Impurity of the denatured alcohol can bring in a combination in anti-freezing means to formation of flakes therefore nozzles can be hammered.
  5. Embedding of the ordinary petrol filter in the pipeline of system of washing of glasses prevents obstruction of washing nozzles.
  6. System of washing of back glass at Audi 80/Avant (versatile person): the tank for water with a rotary bulk branch pipe is under a cover on the right in a luggage compartment.

Regulation of a spraying stream


  1. To insert a needle into an opening of a spraying nozzle.
  2. The opening is in a ball which can be turned by means of a needle.
  3. To turn a nozzle until the water stream, as is shown in drawing, will not start to get on glass.

Nozzles warmed up electricly

Directly before nozzles there is a metal case with the heating resistor. With inclusion ignitions (plug X) on this resistance the current arrives. Nozzles quickly thaw thanks to a high current arriving at first (0,5 — 0,7 And). For temperature keeping the current after a phase of heating falls to exactly 200 мА. If the external temperature makes минус15°С and below, the supporting current raises to 320 мА.

Search of malfunctions


  1. To separate shtekerny connection to a nozzle.
  2. At the included ignition to check the voltmeter, whether tension and whether as it should be contact on "weight" arrives.
  3. Otherwise to look for conducting damage.
  4. If with a food everything is all right, it is necessary to replace a nozzle.

Thus it is necessary to establish nozzles of system of washing of glasses:
and = 20 cm, b = 45 cm, with = 22 cm, d = 48 see.
