A20NHT 2.0 Turbo

The turbocharged petrol, and the quick way to own an Insignia. It's rare and thirsty and holds up well enough, with the direct-injection carbon and the cooling system as the things to watch on a hard-driven car.

Engine and component issues

Carbon buildup on intake valvesdirect injection€400–€700
Rough cold idle, slow throttle response, misfires, gradual loss of low-end response. Direct injection puts no fuel over the intake valves, so crankcase vapour deposits bake on undisturbed.
Check: Not visible without a borescope. Treat it as a service item that's due unless there's a receipt. It's not a fault, it's an unbudgeted maintenance cost.
