How to activate the headlight cleaning function on an Audi A6?

[Matt]

Audi A6 headlight cleaning method is as follows: 1. There is a switch on the left side of the driver's compartment. Turn the switch to turn on the headlights. 2. Turn on the headlights, then push the turn signal lever forward once to activate the high beams. 3. Finally, press and hold the windshield wiper control lever toward the steering wheel for 5 seconds to clean the headlights. There are two structural modes for headlight cleaning systems: 1. Wipe/wash system. This system can only be used with glass lenses, as plastic lenses, despite having wear-resistant coatings, are relatively sensitive to mechanical cleaning. This type of cleaning system can still be seen in older generation models. 2. High-pressure cleaning system. The high-pressure cleaning system can be used with both glass and plastic lenses. The cleaning effect mainly depends on the distance between the nozzle and the lens, the size of the water droplets, the contact angle, the speed of the water spray, and the amount of water sprayed.
