£1,100

2High Likelihood

DPF blockage and failed regenerations

DPF or engine warning light, sluggish acceleration, cooling fan running after shutdown, rising fuel use, or limp mode.

How to check

Estimated Repair Cost

£1,500

3Moderate Likelihood

Turbocharger wear or boost leak

Whistling under load, loss of power, smoke, oily pipework, or a delayed surge instead of smooth boost.
