Common problems

1High Likelihood

DPF blockage and oil dilution from repeated regenerations

DPF or engine warning lights, rising fuel use, frequent fan activity, a hot smell after stopping, limp mode, or the oil level creeping up on the dipstick.

How to check

Warm it fully, then drive at steady A-road speed for 10-15 minutes and watch for warning lights or a sudden drop in response.

Estimated Repair Cost

£1,200

2High Likelihood

EGR and intake carbon build-up

Flat acceleration, uneven running, occasional engine light, extra smoke under load, or a car that feels more strangled than its power figure suggests.

How to check

Accelerate gently and then more firmly from low revs once the engine is warm.

Estimated Repair Cost

£900

3High Likelihood

Exhaust tailpipe or rear muffler cracking

Blowing noise from the rear, more exhaust smell than normal, or a metallic rattle from underneath.

How to check

Start from cold, let it idle, then drive over a rough surface and listen with the windows slightly open at low speed.

Estimated Repair Cost

£450
