Common problems

1High Likelihood

Rear subframe corrosion

How to check

This usually needs an underside inspection and cannot be judged fairly on a short drive.

Estimated Repair Cost

£3,200

2High Likelihood

DPF blockage and differential-pressure sensor faults

Engine warning light, limp mode, poor pull above town speeds, or repeated regeneration trouble.

How to check

Drive at mixed speeds and then accelerate firmly once the engine is warm.

Estimated Repair Cost

£900

3Moderate Likelihood

Injector seal blow-by

Diesel smell, chuffing from the top of the engine, or black tar-like buildup around an injector.

How to check

Let the engine idle with the bonnet open after starting from cold.

Estimated Repair Cost

£700
