I love the car but I'm having a problem with the glass around the convertible top. I believe this is a defect that is common in these cars. I've been told I have to repair the whole top not just gluing or sewing the window. My Catalytic converter has also gone out .Is this common?Please help.Thanks!I didn't find the right answer from the Internet.References: www.city-data.com/forum/audi/2271563-2009-audi-a4-cabriolet-discuss-any.html#ixzz52N37j1xIPromo Marketing Video Animation
