Okay so this has been a bad week for my car. It's a 2003 Audi a4 1.8tqm and I was sitting in it last night when my coolant shot out and filled my engine bay with smoke. I found where it shout out, and it is under my intake manifold. It's a plastic flange looking thing with a hose on top. Anyone know what this is called? And why this would happen? Also a DIY on replacing would be awesome! I'm tearing the car down tonight and if no responses by then I will try and get some pictures. All help greatly appreciated!!
