When I was cleaning under the hood I found a hose fitting with no hose attached. This is on the top side of the curved tube that goes between the air cleaner and the turbo. There is a plastic elbow in a rubber grommet, and it is at a 90 degree angle. Looks to be for a 3/8 or so hose..Can't for the life of me figure out where it goes. There isn't any loose hoses anywhere! Does this car have EGR?? Thanks! John
