i've just bought a citroen c4 1.6 diesel. the engine management light is on, i've been told that it is because the car has been stood still for a while and it will turn itself off when its been for a good drive. is this true? or is it something thats likely to cost a lot of money?
you could try what you have been told but it really should go onto a code reader to see what is causing your problem,once the fault is fixed,then the fault can be deleted
