Hi Guys,

Engine management light on and off and then on again. Something to do with the evap system, any hints on where to look, I don't see any split pipes, I put a dab of vaseline around the gas cap seal as I know leaking gas caps can cause issues.

Thanks 👍

Things to check:

That you have not inadvertently over filled the gas tank recently. Modern tanks should not be brimmed.

The vent from the carbon cannister is not blocked.

The Purge Valve is functioning.

There might be a thermal vacuum valve in the system, it will be linked to the purge valve if present. If so check this.

You'll need a workshop manual to check all of this but these are some on this site you can download.

Thanks Aldfort,

Would you know where the purge valve is on the 1.0 engine. I had a look and tbh I couldn't see it , it's the wife's car and I've had a quick look, thanks for responding

Sorry, I drive a 1.5 but the valve will be somewhere in the inlet tract. The intent is to suck the fumes out of the carbon cannister.
