Megane 225 issues

[55plate225]

Hi,

I'm new here, I bought a Megane 225 yesterday, 48k FSH, 55 plate, I paid £4800 for it! (Don't know wether that is good or bad) anyways,

The issue I'm having is the management light keeps coming on when idling, sat at traffic lights or stopped with the engine running the management light is on and flashing, then when I pull off about 10 seconds later the light will go out and stay out. Another thing I've noticed is the car seems to have a rough idle which wasn't apparent when I bought the car, and a very loud knocking/ticking noise? Sorry I can't describe it any better. Does anybody have any ideas on what it could be? I have to think I've wasted almost £5000!

Missfire, If it has warranty use it, this will be covered with the short time you have owned the car. Spark plugs, coils, injectors will be one the causes of this
