Servicing windshield wipers and washer fluid nozzles (Skoda Superb B6)

Note: If the wash field is uneven due to dirty nozzles, remove them, wash them in the reverse direction, and then blow them with compressed air in the reverse direction. Do not use any objects to clean the nozzles.

1. Over time, road film accumulates on windshield wiper blades, reducing their effectiveness, so the blades should be regularly washed in a mild cleaning solution or replaced.

2. Wiper blade assemblies should be inspected regularly. If inspection reveals hardened or cracked rubber on the blades, replace them. If inspection reveals nothing unusual, wet the windshield and operate the wipers briefly. Uneven marks from the blades or streaks on clean glass indicate that the blades should be replaced.

3. If the wipers do not clean the windshield well enough, the reason may be wax particles that got on the glass when the car passed through an automatic car wash. These particles can be removed by using a detergent with wax-dissolving properties as an additive to the washer fluid (see Specifications). You can also use glass cleaning cloths G052 522 A1 according to VW specification to remove wax.

Checking and adjusting the washer fluid supply nozzles

4. Correctly installed fan-type nozzles for supplying washer fluid to the windshield require virtually no adjustment. The jets should hit the glass in a cone shape. The fluid supply areas are shown in Illustration 7.4a. It may be necessary to adjust their height if there is a difference in the heights of the washer fluid supply. To increase/decrease the height, turn the regulator (2 in illustration 7.4b) with a screwdriver counterclockwise/clockwise.







5. The jet from the fluid supply nozzle onto the rear window when the vehicle is stationary should hit the window at a distance (In the accompanying illustration) above the nozzle. Use a suitable needle to adjust.



6. When the vehicle is stationary, the washer fluid should be supplied to the headlights at the points (A and B in the accompanying illustration). If this is not the case, or the jets are uneven, replace the corresponding nozzle or adjust it. To adjust, pull the nozzle out to the stop and change the position of the nozzles so that the rod of the MP8-524 device alternately touches points (A and B).

Checking and adjusting the parking position of the windshield wiper arms

7. After switching off, the windshield wiper arms should stop in the parking position. To extend the service life of the windshield wipers, after every second switching off, the arms are set to an alternative parking position (from the normal parking position the levers are slightly moved upwards). For the rear window wiper, this function can be switched off/on (see Chapter "Controls and operating techniques"). The following check applies to the normal parking position. You can verify this position by observing the brushes when the windshield wipers are switched off several times in a row.

8. The parking position of the windshield wipers is set correctly if the brushes are on the corresponding marks on the glass with a tolerance of ±2 mm (see accompanying illustration). The rear window wiper parking position is set correctly if the wiper blades are at a distance (And in illustration 7.5) from the bottom edge of the glass.





9. Adjustment of the parking position of the windshield wipers is carried out by moving their levers with their mounting nuts loosened (see Chapter 12). After adjustment, tighten the nuts to the torque specified in the Specifications.

Removal and installation windshield wipers

10. The levers can be moved away from the windshield only from the service position. To set the windshield wiper to this position, with the hood closed, turn the ignition on and off, and then within 10 seconds move the right steering column switch to the lower position. The levers return from the service position to the parking position the next time the ignition is turned on and the right steering column switch is moved again, or the vehicle is moving at a speed of more than 6 km/h.

11. To remove the frameless windshield wiper blade, move its arm away from the glass, press the button (1 on the accompanying illustrations) and pull the brush in the direction of the arrow (2). To install the brush, insert it into the support in the opposite direction until it locks, so that the button appears in the slot. Installation is carried out in the reverse order (see illustration 7.9b). A longer brush is installed on the driver's side.
