It means you have something wrong with your emissions.

Check the hose that goes from the Evap Valve (usually a round plastic valve) to Throttle body. Maybe it is too soft and when there is a vacuum it cloggs.

Have a look here http://www.permoveo.ltd.uk/tabid/122/OBD-Error-Code/P0443/Diagnostics/Renault/Default.aspx

Thanks dbug that is where I originally got my info from.  :y

My reading of this is that it is for removing vapours from the petrol tank and the ecu is not seing a response from the solenoid as there are no other error codes. It has just happened again when the petrol light came on  ???

I just want to know where it might be so I can fault find. Dont even know what to look for ? is it under bonnet or near tank or under wheel arch (one suggestion on google search but could not see anything).

probably a break in the loom somewhere. The ECU will only check for a resistance in the wiring. It'll not be able to tell if the valve is working.

there will be a small-bore hose coming out of the inlet manifold to the valve. Go for a valve screwed to either the manifold or on the bulkhead or inner wheelhouse.
