The factory-fitted windscreen wiper blades are coated with graphite. The graphite coating ensures that the windscreen wiper blade moves quietly over the windscreen. If the graphite coating is damaged, the windscreen wiper will become louder.

Damaged wiper blades should be replaced immediately. Windscreen wiper blades can be bought from a qualified workshop.
