The air filter housing on the V6 TDI is nearly identical with the 3.6ltr, both have a metal heat shield cover on engine side of the filter.
On the V6 there is a sliding clip on the breather tube and this slides onto the edge of the shield to hold the breather tube vertical so I expect the 3.6 tube is held in the same way.
