Coolant level drops, a sweet smell or hot smell appears, the engine light comes on, or the car goes into reduced power. Some cars show few warning signs before the recall fault is found.

How to check

Start it from cold, let it idle, then drive until fully warm and stop with the bonnet open.

Estimated Repair Cost

£900

2Moderate Likelihood

DPF loading and failed regenerations

Fan running after shutdown, poorer fuel economy, a warning light, reduced power, or a car that feels strangled at higher load.

How to check

Drive it for 15 to 20 minutes including a steady faster section, then note how it responds under a firm but normal acceleration.

Estimated Repair Cost

£775

3Moderate Likelihood

Coolant loss from thermostat or related housing leaks

Repeated low-coolant warnings, a sweet smell after a drive, or dried coolant residue around the engine bay are common clues.

Run the car to full temperature, then leave it idling briefly after the drive.
