Mann Filter fuel filter WK 69/2 — high-efficiency diesel protection with water separation

MANN-FILTER WK 69/2 is a high-efficiency fuel filter engineered to protect modern diesel injection systems from particles, rust and water for reliable engine performance.

Modern engines demand cleaner fuel and more precise protection than ever before. The MANN-FILTER WK 69/2 uses a MULTIGRADE F filter media and robust chemical-resistant materials to remove contaminants and separate water, helping to prevent damage to fuel pumps and injectors while maintaining optimal fuel flow and minimal pressure loss. This is a purpose-built replacement part meeting OE-quality expectations for many European vehicle applications.

How does the WK 69/2 protect sensitive fuel injection components?

The filter captures dust, rust, dirt and micro-particles before they reach the pump or injectors, reducing wear and clogging. Its multilayer media balances fine particle retention with consistent flow to avoid pressure spikes.

• MULTIGRADE F media for high filtration efficiency
• Removes both solid contaminants and separates water from diesel
• Prevents abrasive damage to high-precision injection parts

What performance features ensure reliability in extreme conditions?

Materials are selected for chemical resistance and thermal stability, so the filter keeps functioning at high and low temperatures. The design reduces fuel pressure loss to preserve pump efficiency and engine responsiveness under load.

• Chemical-resistant construction for longer service life
• Stable operation across wide temperature ranges
• Engineered for minimal pressure drop and consistent fuel flow

How effective is the WK 69/2 at separating water from diesel?

When assessed under diesel test conditions, this filter achieves near-complete fuel/water separation, protecting metal components from corrosion and preventing water-related injector issues. Efficient separation also aids overall filtration performance.

• Almost 100% water separation in diesel tests
• Reduces corrosion risk to fuel system components
• Helps maintain clean fuel reaching the injection system

Which vehicles and service intervals is this filter suited for?

The WK 69/2 is developed for many European gasoline and diesel applications, notably compatible with select Audi and Volkswagen models. Follow your vehicle manufacturer’s recommended replacement intervals or an experienced technician’s guidance for best results.

• OE-quality part designed for European car platforms
• Compatible with certain Audi and Volkswagen models (check fitment)
• Replace according to manufacturer service schedule

Who is this for: The MANN-FILTER WK 69/2 is aimed at owners and technicians who need a dependable, OE-quality fuel filter for European vehicles — particularly Audi and Volkswagen drivers seeking durable filtration, superior water separation, and stable fuel flow under real-world driving conditions. It’s also a strong choice for fleet managers and repair shops that prioritize protective components to extend injection-system life and maintain engine performance.
