Detailed Description

LuK DMF023 is a clutch flywheel designed for OE-level fitment on select Volkswagen Passat and Audi A4 platforms, including Audi A4 Quattro and Audi A6 Quattro applications. The dual mass construction is tuned for the specific vehicle application to reduce the drivetrain stress that can occur when a solid flywheel is used in place of the original design.

This part cross-references AMS Automotive 167174 for the same application.

Common Problems This Part Can Address

• Excessive drivetrain vibration at idle or under load
• Harsh clutch take-up during engagement
• Premature wear on engine mounts from vibration transfer
• Gearbox stress associated with incorrect flywheel design
• Crankshaft damage related to drivetrain shock loading

Installation Notes and Tips

Verify the flywheel diameter, tooth count, and step height against the original part before installation. Because this is a dual mass flywheel, proper clutch system inspection is important during service, especially on high-mileage Volkswagen Passat and Audi A4 applications. Confirm vehicle year, engine, and transmission details against the fitment list before ordering.

Quality Assurance

LuK manufactures this DMF as an OE-style replacement built to the original dual mass flywheel concept for the listed applications. The design is intended to maintain the vibration isolation characteristics required by the vehicle platform and support reliable drivetrain operation.
