Ok so I just bought myself a 2006 TDI sedan with Nav and power seat. Kinda rare car with only 73k miles. Well it started vibrating pretty bad on the way home. And I figured it was flywheel. Except now it has a viscious leak from the trans. How bad am I looking here? Anyone had any success welding up the holes? I hate the thought of throwing away a low mileage DSG.
