Lubrication System
The lubrication system is the full flow filtration pressure feed type. The oil fill process at the factory allows for a tolerance of 4mm above to 4mm below the maximum mark on the oil level dipstick. The oil level will depend on the oil temperature and length of time from the last engine switch off.

Drain & Refill Procedure
The ECVT gearbox contains three plugs, one is used for draining, one is used for fill/level and the other for fill only. On the MINI it is recommended that the oil fill takes place from the underside of the gearbox through the fill/level plug. There is another oil fill plug on the top of the gearbox that is used in other applications but is not suitable for MINI due to lack of access.
The ECVT oil change is carried out at every "Inspection" service.

Shut the valve of the hydraulic equipment, to ensure no oil flow takes place in either direction. Lower the vehicle sufficiently, (Note: ensure road wheels are approximately 15 cm off the ground, as it is necessary to operate the vehicle in drive mode.) Ensure the parking and foot brake are applied firmly, start the engine and allow 10 seconds of engine running time before moving the gear lever from P (park). Shift the gear lever into each position and allow the gear lever to rest in each of its positions for 5 seconds before progressing to the next position. The final part of this process will require the gear lever to be moved into the Drive position and the foot brake released. A light throttle application will be sufficient to shift the gearbox through the various ratios, this should be carried out 2 times, after completion apply the foot brake and return the gear lever to the park position. Keep the engine running and raise the vehicle.
With the oil temperature between 30°C and 50°C remove the hydraulic equipment and special tool, (Note: care must be taken to prevent scalding). Should the filler tube run dry very quickly, the gearbox is likely to be under filled. Refit the Special Tool and pump an additional amount of oil into the gearbox. Remove the Special Tool and wait until the oil flow begins to slow and then refit the fill/level plug.
