The clutch is self-adjusting and requires no maintenance. The thickness of the clutch disc is measured with a special reference gauge. Measurements must be taken every 80,000 km.
Checking the thickness of the clutch disc must be carried out in the following order. Park the car on level ground (flyover). Remove the car stiffening plate, unscrew the two bolts and remove the clutch slave cylinder. Fix the hydraulic drive with a wire clamp on the body, do not undock the hydraulic system.
Insert into the hole from under the clutch slave cylinder «Caliber-BMW» (pic. 2.54) and click on it. The lining of the driven disk is considered worn if the red zone is visible on the caliber scale.
