Where is the cabin air filter located in the Audi A6L?

The cabin air filter in the Audi A6L is located beneath the glove compartment on the passenger side. Simply remove the lower interior trim panel and open the cabin air filter cover to replace the filter. The cabin air filter is a crucial component in vehicles and requires regular replacement. Generally, it should be replaced every 10,000 kilometers. Failure to replace the cabin air filter for an extended period can impair the air conditioning's performance and negatively affect the health of the vehicle's occupants. When using the air conditioning for cooling, it is necessary to press the AC button. This action engages the compressor clutch, allowing the engine to drive the compressor. The compressor then continuously compresses the refrigerant and delivers it to the evaporator. The refrigerant commonly used in automotive air conditioning systems is R134a, which also requires periodic replacement. Neglecting to replace the refrigerant can result in slower cooling speeds and reduced cooling efficiency.
