Many BMW E46 owners experience clutch slipping. The engine revs increase but the car doesn’t accelerate proportionally, especially noticeable on hills.

Main Causes

• Worn clutch disc – The most common cause.
• Weak pressure plate – Reduces clamping force.
• Damaged flywheel – Causes vibrations and slipping.
• Air in hydraulic system – Affects pedal feel and clutch engagement.

Solutions

• Replace the full clutch kit (disc, pressure plate, release bearing).
• Resurface or replace the flywheel if worn.
• Bleed the hydraulic system and refill with fresh fluid.
