Anyone able to help on this VAG Com Report?
Of course I have my big vacuum cleaner sound as well...related?

I'm thinking bad O2 sensor? Hoping it is instead of cat...ideas?

If you have a vaccum sound their is air leak check lines, if you have an oxygen sensor code air is coming in from where it shouldn't see if you could narrow it down possibly a line or hose. Best way to chk is when you narrow it to a stop take some dishsoap and water and a spraybottle and just spray a little, if bubbles form you have the problem. Hope that helps
