Luk DMF039 Clutch Flywheel

LuK DMF039 Dual Mass Flywheel

The LuK DMF039 is a dual mass flywheel engineered for select Audi A4, Audi A4 Quattro, and Volkswagen Passat applications from 2000-2005. Built around the original LuK DMF design, it is tuned for the specific drivetrain demands of these vehicles and helps reduce the stress that can come from using a solid flywheel.

Key Features

• Dual mass flywheel design for smoother drivetrain operation
• 23 in. flywheel diameter for the specified application
• 14.77 in. inner diameter and -0.329 in. cup depth/step height
• 135-tooth ring gear configuration
• OE-style fitment for Audi A4, Audi A4 Quattro, and Volkswagen Passat
• Part number DMF039 for easy identification and cross-reference

Detailed Description

LuK DMF039 is a clutch flywheel built to match the requirements of the original dual mass flywheel setup used in these vehicles. The flywheel diameter measures 23 inches, with a 14.77-inch inner diameter and a -0.329-inch cup depth/step height, helping maintain the correct geometry for the clutch system. With 135 teeth, this flywheel supports proper starter engagement and drivetrain operation in 2000-2005 Audi A4, 2000-2005 Audi A4 Quattro, and 2000-2005 Volkswagen Passat models.

This part cross-references AMS Automotive 167170 for the same application. The LuK DMF039 is also referenced by part numbers 50-2781 and 058105266A.

What It Helps Address

• Excess drivetrain vibration from a worn dual mass flywheel
• Noise during clutch engagement or engine load changes
• Premature wear on engine mounts caused by torsional movement
• Gearbox stress linked to an incorrect solid flywheel conversion
• Crankshaft damage associated with improper flywheel damping

Installation Notes and Tips

Verify flywheel diameter, tooth count, inner diameter, and step height before installation. Confirm the vehicle application by year and model, especially for Audi A4, Audi A4 Quattro, and Volkswagen Passat fitment. Inspect the clutch system, starter engagement surface, and related drivetrain components during service so the new flywheel is installed against clean, correct mating surfaces.

Quality Assurance

LuK supplies original-equipment dual mass flywheel technology, and this DMF039 is individually tuned for the listed vehicle applications to maintain the intended drivetrain characteristics.
