2000 PEUGEOT 2062.0L PETROL

The 1.4 and 1.6 petrol engines are known for head gasket failures, especially on cars that have been overheated or poorly maintained. Symptoms include coolant loss, white exhaust smoke and overheating.

The door lock actuators fail regularly on the 206, leaving doors unable to lock or unlock remotely. The driver's door is typically the first to go.

The rear beam axle can corrode severely on UK cars, particularly in salt-laden coastal areas. Heavy rust can lead to structural weakness and MOT failure.

The oxygen (lambda) sensor fails regularly, causing poor fuel economy, failed emissions tests and engine management warning lights.
