Help me please!!

I have a 1.6vvt with 48k on the clock now,I had the a problem on Tuesday were after filling with fuel the Toxic Fume light was flashing and misfiring So the car was promptly booked in to Renault Wolverhampton were they told my it was the coils and changed them, but today Saturday the warning light has come on again but has stayed on and is not flashing also the service light is on what is the cause of this can anyone help me?

Could well be the Camshaft sensor. That normally is a non flashing toxic filter light combined with the service light as you describe. Costs about £75-100 if your out of warranty. You may find the car runs fine alot of the time with this fault.
