Usually it's because it needs a new catalyct converter or because of the emmission control, which is usually just a charcoal canister in older cars if they have one at all. on that model car it should be pretty easy to fix but the hard thing may be trying to get the parts to replace them if need be.

My renault Megane RT 1.6 twin Cam T reg has just failed its Mot emission test Fast Test was OK but failed on Idle Test. Carbon Monoxid to high at Idle Speed reading 1.73 when it should be 0.50 max. I...

if there are no faults showing, then the most obvious thing to do would be to change the air filter, this is a relatively cheap part, but it can make a huge difference to emissions, even if it looks perfectly clean.
also make sure you take the car on a good run before taking it to the test centre to ensure that the engine and catalytic converter are up to operating temperature.

it is possible that the catalytic converter is clogged up and not working properly. the only cure for this is to replace it. the mot tester can usually tell you if he thinks it is the cat. my mot tester is always good for advice, just ask what he thinks could be causing it if the air filter does not make enough of a difference

MOT failure

I can almost guarantee somebody has installed your bulbs the wrong way round I've seen this before many times, of course we're talking about Main beam headlight bulbs, I speak as a Renault technician.
I suggest you take it to the main dealer, I hope I have been helpful.
