  • ✓Look for blue/black smoke on startup and under load
  • ✓Listen for rattles, knocking, or turbo whine
  • ✓Test all electrics including windows, AC, and central locking
  • ✓Check for DPF warning light or recent regenerations
  • ✓Inspect for rust underneath and around wheel arches
  • ✓Request a pre-purchase inspection by an independent mechanic

Known Faults

Timing Chain Failure

Critical
2008-201770,000–140,000 miles£900–£1600

The A20DTH/DTJ 2.0 CDTi Insignia shares the timing chain weakness of the Astra J 1.6 CDTi. Chain rattle on cold start is the warning sign — ignore it at your peril.

EGR Cooler Failure

Severe
2008-201770,000–140,000 miles£600–£1000

EGR cooler failure on the Insignia 2.0 CDTi causes coolant to enter the intake manifold — a serious failure that requires immediate attention.

Turbocharger Failure

Severe
2008-2017100,000–180,000 miles£700–£1200

Turbo failure on the Insignia 2.0 CDTi follows the standard pattern — oil sludge in the feed pipe starves the bearings, often on cars with extended oil change intervals.

Injector Failure

Severe
2008-2017110,000–200,000 miles£350–£1200

High-mileage Insignia CDTi examples develop injector wear, causing rough running and rising oil levels from diesel contamination.

DPF Blockage

Moderate
2008-201750,000–100,000 miles£250–£1300

The Insignia 2.0 CDTi is a fleet rep car often driven on short local trips rather than the motorway runs it is designed for. DPF blockage is endemic on urban-use examples.
