Genuine OE Concentric Slave Cylinder (Release Bearing) – 0A5-141-671S
As an authorised retailer of genuine OE parts, we supply this Concentric Slave Cylinder (CSC) direct from the manufacturer’s original supply chain. The slave cylinder, sometimes called the clutch release bearing, is a critical hydraulic component that sits inside the gearbox bell housing and operates the clutch every time you press the pedal. When it begins to fail, you may notice a soft or sinking clutch pedal, difficulty selecting gears, or fluid loss from the clutch hydraulic system.
This unit (part number 0A5-141-671S) is the genuine OE replacement and is the recommended choice when refreshing your clutch system or carrying out a full clutch replacement.
What the Slave Cylinder Does
When you press the clutch pedal, hydraulic pressure travels from the master cylinder to the slave cylinder. The slave cylinder then pushes against the clutch pressure plate, disengaging the clutch so you can change gear smoothly. Because it integrates the release bearing into a single hydraulic unit, the CSC offers a cleaner, more compact design than older external setups, but it also means the gearbox must be removed to replace it.
Why Choose the Genuine OE Part
- Made to original equipment specification for guaranteed fit and function
- Matches the durability and feel of the unit fitted at the factory
- Reduces the risk of premature failure compared with budget aftermarket alternatives
- Direct replacement, no modifications required
Important Fitment and Installation Notes
Always replace the slave cylinder when changing the clutch. Because access requires gearbox removal, fitting a new CSC alongside a new clutch is considered essential practice. Reusing an old slave cylinder with a new clutch is a false economy and can lead to a repeat gearbox-out job if the bearing fails shortly after.
Bleed the clutch hydraulic system thoroughly after installation. Air trapped in the line will cause a poor pedal feel and incomplete clutch disengagement. On many VAG vehicles, a pressure or vacuum bleed is recommended for best results.
This concentric slave cylinder fits a wide range of popular VW, Audi, SEAT and Skoda models using compatible manual gearboxes.
