AudiForums.com - Audi A4 B6 1.8 quattro problem

I've just bought a 2002 A4 1.8 and I'm trying to get some issues straightened out. I have a serious exhaust smell in the cabin when I run the ac and I have an intermittent bank 1 too lean code. I looked around and I see a hose going nowhere. Any suggestions? [IMG]
