The Mégane II Owners' Club

Hi need a little help took car 1.6 16v petrol megane for its ITV (Spainish MOT) and it failed on high Co2 0.9 I've got no codes up on dash or stored it's had new injectors fitted about 4 months ago along with new coil packs what else can I do

Hi, check the air filter is clean and / or replace it anyway would be next on my list plus cleaning the MAF sensor and checking for any air leaks in any of the induction pipes.

Got it sorted was o2 sensor,and wasn't allowed to buy the part from main dealership,and I needed to get car ITV,d as soon as possible so ended up getting dealers to sort it out now 272€ lighter but cars running fine
Ps I'm in southern Spain and ITV is same as MOT

Hi,
not allowed to buy the part
so much for the EU
glad you got it sorted though
Bob.
