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.

Timing Chain Snapping

Critical

2006-201460,000–100,000 miles£400–£1200

The 1.3 CDTi engine uses a weak single-row timing chain. It stretches and snaps without much warning if oil changes are missed.
