Other Faults on This Variant

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.

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.
