The supercharger is the heart of the MINI R52S and R53 – responsible for the iconic sound and instant power delivery. Although BMW describes the Eaton M45 as “maintenance-free,” in practice the supercharger oil ages over time and loses its lubricating properties. A supercharger service with oil change should therefore be carried out every 80,000–100,000 km to prevent damage to gears and bearings.

• Maintain full performance: Fresh supercharger oil ensures consistent boost pressure and smooth throttle response.
• Extend lifespan: Timely service keeps bearings, seals, and gears well protected.
• Preserve efficiency: A serviced supercharger runs more quietly, cooler, and more efficiently.

When is a supercharger service recommended?

• Loss of power or uneven acceleration: If your MINI feels less powerful, worn bearings or a stretched belt may be the cause – a check is worthwhile.
• Unusual noises: Whining, rattling, or clattering sounds from the supercharger area may indicate oil loss or bearing damage.
• Prevention instead of repair: Even without noticeable issues, the service should be performed approximately every 80,000 km – experience shows this prevents costly supercharger damage.

We perform the supercharger service on the R52S/R53 professionally – including oil change, bearing inspection, and checks of seals and belts. This keeps your supercharger reliable and your MINI powerful.
