Symptoms

Rattling noise from engine bay on cold start
Engine stops suddenly while driving
Car won't restart, engine turns over very quickly (loss of compression)

Root Cause

Infrequent oil changes block the small oil feed hole to the hydraulic chain tensioner. The chain runs slack, jumps a tooth, and snaps.

How To Fix

Preventative: Replace chain every 70,000 miles (£400). If it snaps: The rocker arms are designed to break to save the valves, but the cylinder head must come off to replace them. Cost if snapped: £800-1,200.

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

2006-201440,000–90,000 miles£150–£250

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