Alright i was driving my 2000 audi TT and went to the store to get a drink. I came out and started driving i noticed my boost wasnt as stong as it should be. Also the blowoff was making a weird fluttering noise. Almost like it has a SS blowoff but all it is, is stock. Now if audi's came with turbo boost gages this might be a little easyier to figure out. Can anyone help me out with whats going on??

 

sounds like you blew off a boost line somewhere
