Note: If the spray field is uneven due to clogging of the nozzles, remove them, wash in the opposite direction and then blow with compressed air in the opposite direction. Do not use any objects to clean the injectors.
1. Road film accumulates on the wiper blades over time, reducing their effectiveness, so the wiper blades should be washed regularly in a mild cleaning solution or replaced.
2. Wiper blade assemblies should be inspected regularly. If the inspection reveals the presence of hardening or cracks on the rubber of the brushes, replace them. If nothing out of the ordinary is found upon inspection, wet the windshield and operate the wipers briefly. Uneven brush marks or streaks on clean glass indicate that the brushes should be replaced.
3. If the brushes do not clean the windshield well enough, then wax particles that have fallen on the glass during the automatic car wash may be the reason for this. These particles can be removed by using a wax-dissolving detergent as an additive to the washer fluid (see specs). To remove the wax, you can also use glass wipes G052 522 A1 according to VW specification.
Checking and adjusting washer fluid nozzles
4. Properly installed windshield washer fan nozzles require little to no adjustment. The jets should hit the glass in a cone shape. The liquid supply areas are indicated in illustration 7.4a. It may be necessary to adjust them in height if there is a difference in washer fluid delivery heights. Turn the knob to increase/decrease the height (2 in illustration 7.4b) screwdriver counter-clockwise.

5. The jet from the nozzle for supplying fluid to the rear window when the car is stationary should hit the glass at a distance (B on resist. illustrations) above the nozzle. Use a suitable needle for adjustment.

6. When the vehicle is stationary, the washer fluid must be supplied to the headlights at the points (A and B on resist. illustrations). 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 stem of the MP8-524 tool alternately touches the points (A and B).

Checking and adjusting the parking position of the wiper arms
7. After turning off, the wiper arms should stop in the park position. To prolong the life of the wiper blades, after every second wiper switch off, the levers are set to an alternative parking position (from the normal parking position, the levers move slightly upwards). For the rear window wiper, this function can be disabled/enabled (see chapter "Controls and methods of operation"). Further checks refer to the normal parking position. You can make sure in this position by observing the brushes during several successive shutdowns of the wipers.
8. The parking position of the windshield wipers is set correctly if the brushes in it are on the corresponding marks on the glass with a tolerance of±2 mm (see resist. illustration). The parking position of the rear window wiper is set correctly if the wiper is at a distance (And in illustration 7.5) from the bottom edge of the glass.
7.8 Parking position of the windshield wipers
9. Adjusting the parking position of the wipers is carried out by moving their levers with the nuts of their fastening loosened (see chapter 12). After adjustment, tighten the nuts to the torque specified in the Specifications.
Removal and installation of wiper blades
10. It is possible to remove the levers from the windshield only from the service position. To set the wiper to this position, with the hood closed, turn the ignition on and off, then move the right stalk to the down position within 10 seconds. The levers return from the service position to the park position the next time the ignition is turned on and the right stalk is moved again or the vehicle is driven at a speed of more than 6 km / h.
11. To remove the frameless wiper blade, move its lever away from the glass, press the button (1 per resist. illustrations) and pull out 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 in the reverse order (see illustration 7.9b). The longer brush is installed on the driver's side.
