[EliRose]

Audi A6L's cabin air filter should be replaced every 30,000 kilometers, with the replacement interval adjustable according to actual driving conditions. Functions of the car's cabin air filter: 1. Ensures the filter fits tightly against the housing to prevent unfiltered air from entering the cabin; 2. Separates solid impurities such as dust, pollen, and grinding particles from the air; 3. Prevents the car windows from fogging up, ensuring clear visibility for drivers and passengers. The Audi A6L was the first Audi model introduced to the Chinese market. In terms of body dimensions, it measures 5050mm in length, 1886mm in width, and 1475mm in height, with a wheelbase of 3024mm.
