Recently Added Faults

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.

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.

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.

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.

DPF Blockage from Family Use

Moderate
2005-201440,000–90,000 miles£200–£900

The Zafira Mk2 1.9 CDTi is the classic family MPV diesel — used for exactly the kind of school runs and local trips that block DPFs. It is the most commonly reported Zafira fault.
