My question is that the engine management light stays on constantly when driving

The computer in the car has detected a problem, its a warning to get it checked and not drive around with the light on as you may be doing damage to something expensive, like the cat for example.

The light on the dashboard only signifies a fault, but not which fault. To find the fault code that causes the light on/flashing the car needs to be connected to Lexia or OBD2.

A cheap, generic OBD2 reader, like this one on Amazon would suffice to read the codes on a Citroen C3 petrol 1.4
