Symptoms

Clutch pedal stays flat to the floor
Difficulty engaging gears, especially 1st and Reverse
Pool of brake fluid under the gearbox bellhousing

Root Cause

The seals inside the concentric slave cylinder wear out. Because it is mounted inside the bellhousing on the gearbox input shaft, the entire gearbox must be removed to replace a £40 part.

How To Fix

Check brake/clutch fluid reservoir level (it will be low).
Gearbox must be removed to access the CSC.
Always replace the entire clutch kit at the same time, as the leaking fluid ruins the friction plate.
Cost: £400-800

Other Faults on This Variant

Electronic Parking Brake (EPB) Motor Failure

Severe

2014-202150,000–100,000 miles£200–£300

The electronic parking brake actuators on the rear brake calipers frequently seize or burn out, leaving the handbrake stuck on or refusing to engage.

DPF Pressure Sensor Pipe Split

Moderate

2014-202160,000–100,000 miles£5–£100

A tiny rubber hose connecting the DPF to the exhaust pressure sensor splits frequently, causing limp mode and preventing DPF regeneration.

Front Radar / Anti-Collision Sensor Failure

Minor

2014-202140,000–90,000 miles£600–£800

The front radar sensor (used for emergency braking) is poorly sealed and highly vulnerable to water ingress and stone chips, causing the entire safety system to shut down.
