Would this be related to having a Turbo Back Exhaust with a 200 Cel cat on the car? It idles a bit weird at times aswell.
Would a remap with the fueling sorted fix this issue. I have previously replaced the MAF, Charcoal Canister and the PCV.

I plan on getting it remapped at some point. Just wondering if now would be best to help with these codes.

Thanks in advance

Yeah because of the sports cat.  EU emissions mandates the money light comes on when the cat efficiency falls outside of spec, but it doesn't change how the engine runs.

I couldn't get rid of the evap codes until I'd replaced the N80 valve, the charcoal can and the rigid line that connects the can to the line by the brake reservoir.

Ahh right. I spoke to the local Revo guy and mentioned the errors and if they would just need to be mapped out.

I have replaced the hard pipe and canister. I may just buy a N80 and fit before it gets mapped.

A Revo Stage 2 map will sort the warning light.
