How often should the air filter of an Audi A6L be replaced?

The air filter of an Audi A6L should be replaced approximately every 30,000 kilometers. The Audi A6L has air filters located at the air intake and blower of the air conditioning system. Taking the 2020 Audi A6L as an example, it belongs to the mid-to-large-sized car category, with body dimensions of: length 5038mm, width 1886mm, height 1475mm, and a wheelbase of 3024mm. The fuel tank capacity is 73 liters. The 2020 Audi A6L features a five-link independent suspension at the front and a five-link independent suspension at the rear. It is equipped with a 2.0L turbocharged engine, delivering a maximum horsepower of 190PS, a maximum power of 140kW, and a maximum torque of 320Nm, paired with a 7-speed dual-clutch transmission.
I think the replacement interval for the Audi A6L's air filter mainly depends on driving habits. My car is a 2015 A6L, mostly used for commuting in the city where there's a lot of dust, so I generally replace it every 15,000 km. Once I delayed it to 20,000 km without changing it, and the filter was as dirty as a black rag. The engine felt sluggish, and fuel consumption increased by a few tenths of a liter, which scared me into rushing to the dealership for service. Actually, a clogged filter not only increases fuel consumption but also forces the engine to suck in more impurities, which can lead to problems. It's generally recommended to replace it annually or every 10,000 to 20,000 km. If you frequently drive on dusty roads or in areas with poor air quality, like during smoggy days, check it earlier. Doing it yourself isn't difficult—buying an OEM part costs just a few dozen bucks, and you can replace it by simply opening the hood. Remember, timely maintenance keeps your car running smoothly.
Over the years of driving an Audi A6L, I've learned that air filters should be replaced when necessary. It's best to change them approximately every 20,000 kilometers, but adjustments should be made based on road conditions. For instance, if I mostly drive on highways with less dust, the filter can last longer. However, during holidays when driving on rough rural roads with sand flying everywhere, I need to check if the filter is clogged before reaching 10,000 kilometers. If the filter isn't clean, air can't get through, and the engine will suck in dust, wearing out the piston rings—repairs for that can be expensive. I make it a habit to inspect the filter's color every six months; if it turns black or hardens, I replace it. Even cheaper aftermarket parts work fine. In short, don't cut corners—vehicle performance depends on attention to detail, and good habits save both hassle and money.
