BMW 340i xDrive Clutch Replacement Cost

When the vehicle is in gear, power is transmitted from the engine through the clutch to the transmission. Pressing the clutch pedal disengages the clutch friction disc from the flywheel, momentarily disconnecting the engine from the transmission and allowing shifting between gears.

A failed clutch could slip or shudder, or it could be unusually difficult to press the pedal. Changing gears may become more difficult. The engine will rev but speed will not increase or the vehicle may not move.

No, it's usually impossible to drive with a failed clutch. Even if the transmission can be put into gear, the worn clutch disc will not be able to transmit enough torque to move the vehicle.

Replacement intervals vary by vehicle and driving conditions. Similar to brake pads, clutches do not have a recommended replacement mileage. They do wear out, but some will last over 100,000 miles. 

The technician will inspect the clutch hydraulics and clutch cable, if equipped. Shifting problems may arise from leaking clutch master cylinders, misadjusted clutch cables or worn pivot arms. If other clutch issues have been ruled out, the transmission will be removed and the clutch, pressure plate and flywheel will be inspected and repaired as needed.

The technician will remove the transmission or transaxle from the vehicle. The release bearing, pressure plate and clutch will then be removed from the engine. The flywheel may be removed for resurfacing or replacement, and the pilot bearing will be removed from the rear of the crankshaft. The new components will then be installed, and after assembly, the technician will check for proper operation.

Engine oil or transmission fluid leaks can damage a clutch. When replacing the clutch, any leaks should be diagnosed and repaired to avoid recurring problems. As a preventive measure, it's not uncommon for a shop to recommend replacement of the rear main seal, the transmission input shaft seal, or other parts, even if they haven't failed. It's a good insurance policy against expensive future repairs. Also, when driving, avoid "riding" the clutch — that is, keeping your foot lightly on the pedal. Riding the clutch will wear it out more quickly.

No, clutch replacement is a job for an experienced technician. Transmission removal is required, and special tools are often needed for removal and seating of the new clutch components.
