This is a hose that has been added to a 1991 TT. I don't know what it is for, but I am certain it is not stock. I want to remove it and cap the fitting on the recirc, but I'd like to know what it was put there for first so I don't mess anything up. It is the hose going into the pipe that goes on the DS of the plenum at a 90° angle and into the PS recirc valve. The recirc valve is drilled and tapped for a fitting to add this hose.
And here is a teaser for those who have followed my posts at all... Finally!
