I have an 07 307 HDI which has all of a sudden decided it will not turn over when the key is turned. Battery is good as lights, central locking etc all work fine and battery is only a couple of months old. Spedo and taco do not light up when key is turned, could be normal, but ignition and warning lights do. There is nothing from the starter motor, not even a click like when the battery is flat. Relay does make a click sound when key is turned. ????
