How often should I change the engine air filter on my 2025 Audi A8 L?

• To keep the A8 L performing at peak efficiency, schedule appointment for a quick inspection.

What is the difference between an engine air filter and a cabin air filter?

• The engine air filter protects the engine and turbo system; the cabin air filter protects passengers by filtering pollen, dust, and pollutants entering the HVAC system.
• Both affect comfort and performance: a clogged engine filter reduces power and economy, while a clogged cabin filter reduces airflow and interior air quality.
• Audi North Atlanta uses OEM filters and documents replacements so warranty integrity is preserved — remember, warranty-covered repairs must be performed at a certified dealership for validation.

What are signs of a bad air filter?

• Engine filter: reduced acceleration, lower MPG, unusual intake noise, or a check-engine light related to airflow sensors.
• Cabin filter: reduced HVAC airflow, unpleasant odors, or increased dust inside the cabin.
• If you notice symptoms, take advantage of our quick inspections and service specials, and schedule service to restore performance and comfort.
