I have a 63 plate 2008 with 50k miles. I've just been told the catalytic converter is cracked. The garages has only linked to diagnostics. They've quoted £900+ but have said Peugeot will pay 50% as a goodwill guesture. They said driving hasn't caused the issue. I don't know how it could be cracked. Does anyone know if there is an issue or am I just unlucky. Thanks
