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.

Estimated Repair Cost

£1,200

2Moderate Likelihood

Automatic transmission fluid neglect causing harsh or hesitant shifts

Delayed drive engagement, revs rising before the next gear takes up, or a jerky shift when warm.

How to check

From fully warm, move away gently several times and then add light throttle through the first few upshifts.

£350

3High Likelihood

Exhaust tailpipe or rear muffler cracking

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