We recommend replacing your Audi A6 fuel filter every 40-50,000 miles. The factory doesn't specify a specific interval for changing the fuel filter. However, a good rule is to change your fuel filter around the same time as your engine tune up.



In most cases the fuel filter is one of the most overlooked scheduled maintenance items on a vehicle. Your Audi fuel filter is responsible for the removal of dirt, dust, soot, particles, contaminants, water and other substances that can negatively affect the efficiency of your engines fuel injection systems. A bad or plugged fuel filter can result in poor fuel economy and a lack of engine performance. Regular fuel filter changes can result in the protection of your fuel injection system, trouble-free engine operation, and help avoid inconvenient breakdowns and costly engine repairs.
