Update: well I now only have one code left. It is a p0455 large evap leak.
Does anyone know where the common fail points are? My canister and everything is in the driver rear fender. Could this be a ldv? Or a hose issue. I went down there but could not visibly see and cracks/splits/holes.
Its normally a hose issue, especially where the tube passes the rear axle. The rubber hoses dry out and crack. But ofcourse it could be at some other point as well, even the gas cap could be the problem. Check first if its fastened ok.
