So recently picked up a 2003 S80 T6, beautiful car, runs fantastic and drives the same. After working out a few little issues I am down to getting a P0447 and P2400 trouble codes off the ecu. Looking for a little guidance as to where to start poking around to fix these? Drive-ability is fine it has full power and all the good stuff but don’t like seeing CEL. I know they both point towards a problem in the leak detection pump but good GD! You would have to remove the entire rear cradle just to get the thing out! Any help is much appreciated!
