A light came on today with a picture of a car and a spanner going through it. what does this mean? i've had the car for about a year now and i've never seen it before. cheers
It is the electronic diagnostic light (sister light to the engine management light) It means the car has found a fault and need to be plugged into a diagnostic machine to find out what happened.
Double checked with an Astra handbook and it is a electronic warning light. The service indicator is a counting down mileage total when you turn the ignition on.
