I have a renault clio dci 1.5 it's a 51 plate so about 9/10 years old? When I put the key in the ignition the lights on the dashboard come on except the diesel light and when I try to start the engine there is no response what so ever, mechanice I have tried are puzzled by this and can't work out why the car won't start, one guy said it could be the ECU? And suggestions would be great thank you.
