Last week the programme ran a major piece which revealed that a malfunctioning ignition system on some early 307 hatchbacks could – in the worst cases – lead to a fire under the bonnet.

Following ignition, keys were remaining stuck in the 'starter' position, and not returning to the 'drive' position – eventually causing the starter motor to burn out.

Watchdog accused Peugeot of failing to mention fires in any subsequent vehicle recall notices, and failing to tell customers about the fundamental safety of cars suffering from the ignition problem.

Peugeot declined an invitation to appear on the programme, but sent a statement saying the company “regrets the events that have occurred”. The statement also said: “In the instance when the part did malfunction, drivers were alerted by warning signs such as the key not returning to the 'drive' position, an abnormal noise or unusual smell.

“As the recall campaign progressed several cases of starter motor burnout were identified, and we therefore renewed the campaign using DVLA data to reach every possible owner.”
