Ihave the wretched warning light on with code p1147,evap purge valve,i have checked the filler cap and connections which seem fine,so will replace the gizmo itself,i have part no 002 03-030 stamped on it,but cannot find one listed.does anyone know an oem number for a compatible part,esr 4032 comes up but i cannot get a new part ,as out of stock and i dont want to go down the 2nd hand route.
