engine control module (ECM) otherwise known as the ECU

may need reset. possibly the fuel map has developed an error causing over fuelling. i know a few owners who've had ECU problems similar to this and it was moisture on the ECU connectors. try disconnecting it, see if there's any corrosion and clean off, then spray some wd40 on and reconnect. what clio is it? 1.2 16v?

the other fault code is a lamda sensor problem. the'te located near the exhaust silencer i think? and they can def cause emmision problems. could need a clean or replaced. i would clean it 1st. replacement is around 60 quid tho i think
