Hi,
I have a megane 2 1.4 03 reg, yesterday the toxic fume filter warning lamp started flashing along with a missfire, after reading the FAQ's I removed the plugs and No 4 was much darker colour than the other 3, today bought new plugs and 1 new pencil coil, replaced the coil on No 4 and missfire cured, refitted the original coil= missfire back, confirming No 4 coil defective, changed all 4 plugs and re-fitted new coil to No 4, miss fire gone but toxic fume warning lamp still on but now constantly on not flashing.
what have I missed?

You might need to get the codes cleared.
It will probably go off on it's own if you just keep using the car.
Might take a good few journeys though.
