Which point on the wiper should be used for the 30 cm reference on a Volkswagen?

It is recommended to use the point between the right wiper's root and the right washer nozzle as the 30 cm reference. Main components: The electric windshield wiper is driven by a motor and generally consists of a wiper arm, wiper blade assembly, rubber blade, blade holder, blade support, wiper arm spindle, wiper base plate, motor, reduction gear, drive linkage, drive link hinge, wiper switch, and wiper switch knob. Working principle: The left and right wiper blades are pressed against the outer surface of the windshield by the wiper arms. The motor drives the reduction gear to rotate, and through the reciprocating motion of the drive linkage, it causes the wiper arms and blades to swing left and right, thereby wiping the windshield.
Back when I was learning to drive, my instructor taught me this trick, which is super practical. On Volkswagen wipers, that little bump is usually a 30cm reference point—it's the small nodule near the right side of the wiper arm. Sitting in the driver's seat, first adjust your seat so you're sitting upright, then locate that point. When it aligns with the top of the curb, the right side of the car is roughly 30cm from the roadside. As a beginner, I practiced this often. At first, I could never get it right and had to drive slowly, focusing straight ahead while using peripheral vision to check the point. After a few tries, it became second nature. The key is not to rely solely on your eyes—double-check with the rearview mirror to ensure safety. I also recommend practicing in an open area, like a parking lot, to avoid pedestrians or other cars.
I've been driving for over ten years, and the 30cm reference point on Volkswagen wipers is easy to find - it's that small raised bump on the outer side of the wiper arm. When parking, I first check the right rearview mirror to estimate the distance, then align that point with the curb edge. With enough practice, it becomes second nature - just a quick maneuver and the car parks perfectly. I've also learned that slower speeds (under 10km/h) work best for accuracy. Before long trips, I always inspect my car; if the wipers are muddy, I clean them to ensure clear reference points. While this method works for most vehicles, Volkswagen's wiper design is particularly thoughtful with more visible markers.
