Luk DMF225 Clutch Flywheel

LuK DMF225 Dual Mass Flywheel

The LuK DMF225 is a clutch flywheel engineered as a dual mass flywheel for smoother drivetrain operation. It uses two rotating masses with an integrated arc-spring damping system to absorb engine torsional vibrations before they reach the transmission.

• Dual mass flywheel design for torsional vibration damping
• Integrated arc springs help isolate engine pulsations
• OE-style replacement for select Audi applications
• Built for drivetrain smoothness and clutch engagement consistency
• Cross-reference part numbers: 0B2 105 266 R, 4150974100

Fitment Details

• Fits 2013-2017 Audi A5 Quattro, N/A
• Fits 2010-2011 Audi A5 Quattro, N/A
• Fits 2009-2016 Audi A4 Quattro, N/A

How It Works

In a dual mass flywheel, the two masses rotate against each other through a damping mechanism rather than acting as a single rigid unit. That construction helps reduce drivetrain vibration and supports smoother operation in Audi A4 Quattro and Audi A5 Quattro models where refined clutch and transmission behavior matters. The LuK DMF225 is a direct-fit clutch flywheel solution for these applications.

Common Issues It Can Address

• Excessive drivetrain vibration at idle or under load
• Clutch shudder during takeoff
• Rattling or knocking noises from the flywheel area
• Harsh engagement feel during shifting
• Wear-related loss of damping performance in the flywheel assembly

Installation Notes

Inspect the clutch system, release components, and transmission mating surfaces before installation. Replace worn related parts as needed and follow the vehicle service procedure for torque values, alignment, and fastener sequence. Confirm application by matching the part number DMF225 to the vehicle’s OE reference and fitment listing before installation.

Quality Assurance

LuK, part of Schaeffler, introduced dual mass flywheel technology more than 30 years ago and continues to supply drivetrain components built around that design principle. The DMF225 reflects that OE-focused engineering approach for select Audi fitments.
