Common problems

1High Likelihood

EGR cooler internal leak and fire risk

Coolant level drops for no obvious reason, there may be a sweet smell, white smoke when warm, or a drivetrain warning. Some cars show few warning signs before it becomes serious.

How to check

Warm the car fully, then let it idle for a minute after a normal drive and pay attention around the bonnet and exhaust.

Estimated Repair Cost

£1,100

2High Likelihood

DPF regeneration failure and blockage

Engine light or DPF warning, sluggish performance, cooling fan running after shutdown, poor fuel economy, or limp mode.

How to check

Drive it long enough to reach full temperature, then accelerate steadily through the mid-range and watch for warning lights or flat performance.

Estimated Repair Cost

£1,500

3High Likelihood

Boot water ingress from rear drains or seals

Musty smell, condensation, damp boot trim, water in the battery or amplifier area, odd electrical behaviour after rain, or static from the audio system.

How to check

Open the boot after the car has been standing outside or after a wash, lift the floor panels and use the normal cabin controls and audio.

Estimated Repair Cost

£600
