About this product
When flywheel performance matters, the BF 20090344201 delivers — built to the same dimensional and material standards as the original part it replaces. The part is built to the following specification: Number of Teeth: 160, Width [mm]: 70 mm, Operating Mode: Mesh Filter, Material: Polyurethane, Inner Diameter [mm]: 235 mm. Each dimension is checked against the OEM reference to ensure the component seats and functions correctly first time. This part supersedes original equipment references: 01 0330 442001, 10133, 3421 601 012, 442 030 19 05 and 4 more. Matching these numbers confirms a like-for-like replacement with no loss of function. BF is a recognised supplier of automotive replacement components to independent workshops and dealer networks across Europe. All parts are sourced from authorised distribution channels and carry full manufacturer traceability — you receive exactly the same component supplied to professional garages and dealer workshops. If fitment or specifications do not match your vehicle, our technical team can help identify the correct alternative — use the vehicle selector or contact us with your VIN for a guaranteed-fit recommendation. Replacing worn components on schedule preserves your vehicle's safety, reliability, and resale value — and aftermarket parts from established brands deliver OEM-equivalent performance at a fraction of the dealer price. Every part is dispatched from our UK warehouse with a 30-day money-back guarantee and free hassle-free returns.
Flywheel buying guide
Why replace this part?
The flywheel is a precision-balanced steel disc that stores rotational energy to smooth power delivery between firing strokes, provides the ring gear surface for starter motor engagement, and on manual gearbox cars provides the friction surface for the clutch disc. A dual-mass flywheel (DMF) adds a spring-damper mechanism to absorb drivetrain vibration. Worn or heat-cracked flywheels cause clutch slip, rough engagement, and gear rattle.
Signs you need a replacement
- Clutch judder or shudder on engagement
- gear rattle at idle that disappears with clutch depressed (DMF)
- vibration through the gearstick
- starter motor grinding (worn ring gear)
- scoring or hot spots visible on friction face
- poor clutch bite point
When to replace
Always replace the flywheel when replacing the clutch on DMF-equipped vehicles — DMF springs and dampers wear in tandem with the clutch disc. Solid flywheels can be resurfaced if scoring is within limits. Inspect the ring gear for damage.
