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

EGR Valve Failure and Carbon Build-Up

Moderate

2006-201450,000–100,000 miles£80–£280

The Fiat/GM 1.3 CDTi is a capable diesel but its EGR valve blocks with carbon deposits regularly. This is one of the most common Corsa D complaints.

Diesel Particulate Filter Blockage

Moderate

2006-201440,000–90,000 miles£150–£800

DPF blockage is endemic on the 1.3 CDTi Corsa, largely because most owners use them for short trips where the DPF cannot self-clean.

EGR Valve Seized Open

Moderate

The EGR valve on the 1.3 CDTi clogs rapidly, usually jamming open and causing terrible starting and idling.
