How it works
Clear information first, then the right engine and specialist for your exact vehicle.
Variant History
The Vauxhall Insignia 2.0 CDTI, powered by the GM Family II diesel engine, was introduced with the Insignia's launch in 2008 and continued through both the Mk1 (A) and Mk2 (B) generations until 2022. It became the backbone of the Insignia range, prized for its torque and motorway economy, but also notorious for a critical oil pump seal and crankshaft design flaw that can cause catastrophic failure.
