Sounds like the engine may be over-fueling.
Has a compression test been done or the exhaust gases analysed?

Hi all I have this problem also. We changed the EGR valve recently and since this the car it chucking when stopped and the abs light is on. I doubt the abs light has anything to do with it but just wondering if the EGR Valve did anything

i had a compression test done and they said that it was fine but i have not had the exaust gases tested but when you drive the car for a bit and then stop and get out you can smell petrol. why is this ?

The charcoal canister 'stores' fuel vapours from the tank, and is 'purged' into the inlet air pipery. The purging is controlled by a solenoid-operated valve, and must only occur under specific engine operating conditions.

If the valve is stuck open, this will be like having an air leak into the inlet system. A 'lumpy' idle being one symptom.....

Hi - I'm not familiar with the Clio, but on my Megane the charcoal canister is in the engine compartment down by the foot of the RH (viewed from the back) wheel arch. It's usually a black plastic 'container', about the size of two baked bean cans.

The purge valve is either integral with the canister, or connected to it by a pipe. The other side of the valve will connect to the inlet air trunking or throttle body or inlet manifold.

Hopefully someone else can help you locate it.

To eliminate the purge valve from your enquiries, remove the pipe from the valve to the inlet side, and plug (seal) the pipe so that no air is drawn into the inlet.
