DEFINITION: The clutch does not engage completely after the pedal is released, after changing gears, or the clutch slips during maximum engine loads, such as climbing hills or high vehicle speeds. Clutch slipping is identified by increase in engine RPM without increase in vehicle speed. Review the Symptoms - Clutch and perform the necessary inspections.

Incorrect clutch pedal height, not allowing the clutch master cylinder to return.

Adjust the clutch pedal position switch. Refer to Clutch Pedal Position Sensor Replacement .

The clutch pedal return spring is broken or missing.

Replace the clutch pedal return spring, if equipped. Refer to Brake, Accelerator, and Clutch Pedal Replacement .

The clutch pedal is binding or sticking.

1. Clear away any items that may be contacting the pedal.
2. Inspect the pedal bushings for ease of movement.
3. Replace the clutch pedal if it is faulty. Refer to Brake, Accelerator, and Clutch Pedal Replacement .

Clutch master cylinder binding or seized.

Replace the clutch master cylinder. Refer to  Clutch Master Cylinder Replacement : Right Hand Drive → Left Hand Drive .

Clutch actuator cylinder binding or seized.

Replace the clutch actuator cylinder. Refer to  Clutch Actuator Cylinder Replacement : M32-6 → F40-6 → D33 → D16 .

Kinked or damaged clutch actuator cylinder front pipe.

1. Inspect for the correct routing of the clutch actuator cylinder front pipe.
2. Route the clutch actuator cylinder front pipe properly.
3. Inspect for loose or faulty engine mounts that may allow the clutch actuator cylinder front pipe to be kinked or pinched.
4. Repair or replace faulty engine mounts.
5. Replace the clutch actuator cylinder front pipe if it is damaged. Refer to  Clutch Actuator Cylinder Front Pipe Replacement : F40 and Right Hand Drive → F40 and Left Hand Drive → LHD - MZ0,MZ4,MR5,MF3 → RHD - M32, MF3, MZ0, MZ4, MR5 → Right Hand Drive with D33 → Right Hand Drive with D16 → Left Hand Drive with D33 → Left Hand Drive with D16 .

Grease or oil contamination of the clutch disc.

1. Repair the source of the oil leak.
2. Repair the source of the grease leak.
3. Clean the contamination from the clutch components.
4. If contaminants cannot be removed, replace the clutch assembly. Refer to  Clutch Pressure and Driven Plate Replacement : LUJ, LUW, 2H0 - MF3, MZ0, MZ4, MR5 → LBS , LNP with MYJ → D33 → D16 and D20 .

Oil-soaked clutch disc.

Correct the leak at its source and install a new clutch disc.

Weak diaphragm spring.

Replace the clutch assembly. Refer to  Clutch Pressure and Driven Plate Replacement : LUJ, LUW, 2H0 - MF3, MZ0, MZ4, MR5 → LBS , LNP with MYJ → D33 → D16 and D20 .

Driven plate that is not seated.
