Blauparts recommends replacing your VW TDI fuel filter at the manufacturers specified replacement interval. The recommended service for the VW TDI fuel filter is to drain or flush it every 10,000 miles and change it every 20,000 miles. You may also want to consider replacing your fuel filter before winter months. Your fuel filter filters moisture and water from your diesel fuel. If moisture is not removed from the fuel filter during cold winter months this can cause emulsified water to form a fuel/ice slush, further restricting the fuel filter causing poor performance.

In most cases the fuel filter is one of the most overlooked scheduled maintenance items on a vehicle. Your VW 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.
