Luk DMF049 Clutch Flywheel

LuK DMF049 Dual Mass Flywheel

The LuK DMF049 is a dual mass flywheel engineered for the 2002-2005 Audi A4 Quattro. It is built around the OE-style dual mass design that helps isolate drivetrain vibration and maintain smoother clutch engagement in demanding transmission applications.

With a 24.1 in. (9.488 in.) flywheel diameter, 15.4 in. (6.063 in.) inner diameter, -0.213 in. (-5.4 mm) cup depth/step height, and 135 teeth, this flywheel is specified for precise fitment and proper starter engagement. The LuK DMF049 is a direct-fit choice for Audi A4 Quattro flywheel replacement work where OE-level dimensions matter.

Detailed Description

LuK develops dual mass flywheels as matched components for specific vehicle applications, and the DMF049 follows that approach for the Audi A4 Quattro. The dual mass construction helps reduce the stress that can occur when a solid flywheel is used in a system calibrated for torsional damping. For buyers searching for a 2002-2005 Audi A4 Quattro clutch flywheel, LuK DMF049 provides the dimensional accuracy needed for proper clutch and starter operation.

This part cross-references 06C105266B and 4150149100 for the same application. When replacing the flywheel on an Audi A4 Quattro, confirming the diameter, tooth count, and step height is essential to maintain correct drivetrain geometry and engagement.

What It Helps Address

• Excess drivetrain vibration during acceleration and shifting
• Premature wear on engine mounts from torsional shock
• Gearbox stress caused by improper flywheel damping
• Crankshaft damage associated with solid flywheel conversion issues
• Starter engagement problems related to incorrect tooth count or dimensions

Installation Notes and Tips

Verify the existing flywheel dimensions, tooth count, and clutch system requirements before installation. On 2002-2005 Audi A4 Quattro models, confirm that the replacement flywheel matches the OE-style dual mass specification and the listed step height before assembly. Inspect the clutch, release components, and related drivetrain parts during service to avoid repeat labor.

Quality Assurance

LuK is an OE-focused drivetrain brand known for application-specific dual mass flywheel engineering. The DMF049 is built to match the vehicle’s original design intent for fit and function in Audi A4 Quattro transmission service.
