Original MANN‑FILTER Oil Filter W 940/50 – For Passenger Cars

The MANN‑FILTER Oil Filter W 940/50 is a premium, OEM‑grade filtration solution engineered for modern passenger vehicles. Designed with precision and durability in mind, it delivers superior protection for the engine’s lubrication system, ensuring optimal performance and longevity.

Key Features & Technical Highlights

• High‑Efficiency Filtration: Utilises advanced multi‑layer media that captures particles as small as 0.5 µm, preventing wear on bearings, pistons, and camshafts.
• Anti‑Return Valve: Integrated valve prevents oil backflow into the engine bay, maintaining proper pressure and reducing contamination risk.
• Robust Construction: Made from high‑grade polypropylene housing with reinforced seals to withstand extreme temperatures and pressures.
• Standard Thread Size: 3/4‑16 UNF (outer diameter 93 mm) – compatible with a wide range of European passenger cars.
• Certified OEM Replacement: Meets or exceeds original equipment specifications for Audi, VW Passat, and other VAG models.

Vehicle Compatibility

The filter is specifically engineered for the following vehicle families:

• Audi A4 (8D2/8D5) – B5, Avant, Limousine variants
• Volkswagen Passat (3B2/3B5) – Sedan, Variant, Wagon
• Other VAG passenger cars with matching engine bay dimensions and thread specifications.

For a complete list of compatible models, consult the manufacturer’s technical data sheet or your vehicle’s service manual.

Installation & Maintenance Guide

1. Preparation: Warm up the engine to operating temperature. Drain residual oil from the filter housing using a suitable container.
2. Removal: Unscrew the old filter counter‑clockwise. Carefully remove, ensuring no oil spills onto the floor or surrounding components.
3. Installation: Apply a thin layer of fresh engine oil to the rubber gasket of the new filter. Screw the filter clockwise until snug; avoid overtightening to preserve seal integrity.
4. Check for Leaks: After starting the engine, inspect the filter area for any signs of oil leakage. Tighten further if necessary.
5. Oil Change Interval: Replace the filter at every scheduled oil change (typically every 10,000 km or 12 months, whichever comes first). Adjust based on driving conditions and manufacturer recommendations.

Performance Benefits

• Engine Protection: By trapping contaminants, the filter reduces friction and wear, extending engine life.
• Fuel Efficiency: A clean oil flow maintains optimal viscosity, contributing to better fuel economy.
• Reduced Emissions: Proper filtration helps keep combustion chambers cleaner, supporting lower exhaust emissions.
• Reliability: OEM certification ensures that the filter meets stringent quality and performance standards.

Quality Assurance & Compliance

The MANN‑FILTER W 940/50 undergoes rigorous testing in accordance with ISO, SAE, and VAG specifications. Each batch is inspected for dimensional accuracy, seal integrity, and filtration efficiency before shipping. The product carries the MANN‑FILTER Genuine OEM label, guaranteeing authenticity.

Environmental Considerations

The filter’s design promotes responsible disposal: it can be recycled as part of automotive waste management programs. By maintaining engine health, it indirectly reduces the need for frequent oil changes and associated environmental impact.

Frequently Asked Questions

Can I use this filter in non‑VAG vehicles?

While the thread size is common, compatibility depends on engine bay clearance and gasket dimensions. Verify with a technical data sheet before installation.

What oil viscosity does it support?

The filter works effectively with all standard automotive oils (5W‑30 to 10W‑40). Always use the oil type recommended by your vehicle manufacturer.

Is an anti‑return valve mandatory?

No, but it is highly recommended for engines that operate under high pressure or have a dry sump system. The W 940/50 includes this feature for added protection.

Conclusion

The MANN‑FILTER Oil Filter W 940/50 represents the pinnacle of filtration technology for passenger cars. Its combination of high‑efficiency media, robust construction, and OEM certification makes it an indispensable component for maintaining engine performance, reliability, and longevity.
