My Ford fiesta 2013 1.6 diesel does not start using the key. When I turn on the engine using the key the car just crank and crank . Using a quick start or pushing the car it starts but the car cuts the diesel immediately and the engine switches off. The car does not idle at all. I was advised of the need for a unichip to override the DPF. The feedback that I got from the DPF specialist pointed to a starter problem caused either by ECU or immobiliser. Could you please give me a quotation for fixing the starting and idling problem of the car.
