Now worries del.

Bit more info for people to help you with.
1st fault was permenant, brake light switch open circuit.
2nd fault was throttle discrepency, 40% sensor 1 & 52% sensor 2.

The first thing to do is check the brake lights are working correctly, very common on 206's & picasso's, usually the lights stick on making the ECU think you are braking & accelerating at the same time, often acompanied by a loss of power aswell.

FIXED.

Replaced brake sensor and replaced throttle sensor H20cooler reset my fault codes and no anti pollution fault anymore. Emlight no longer on.

Brake sensor was noticeably burnt out inside, throttle sensor requires special tool to access internallly so £20 one from breakers seems to work fine.

Many thanks h20cooler
