Looking at a megane saloon , 1.6 auto .

It's very cheap £500 , mot'd until march '18 , the key card and electric windows even work!

However for the last 5 years each years it's failed it's mot on exhaust emissions carbon monoxide , hydrocarbons on 2nd fast idle as well as high lambada reading on 2nd idle.

Each time it's had a re test and got a pass so is the cat shagged or is the car just cold when they test it then they take it out get the engine hot retest it and it passes?
