Hi Everyone!

I own a wonderful 2001 Audi a6 2.7T Sedan...and I am planning on trading it in soon to get myself a 2009/2010 A5.

Anyways...I have a few things I need to fix.

1. Window Regulator clips...I have to replace these. Do I need to replace the clips AND the guides if I do this? Window rolls down perfectly, rolls up not so perfectly. The motor was replaced two weeks ago (I thought that was the initial problem). I found a DIY on youtube but I'm not sure what kind of screw driver he needed to use to unscrew the clips on the window (some weird one...)

2. o2 Sensors in compartment 1. Any ideas or DIY's on these? I couldn't find any....

3. Drivers side headlight getting dirty on the inside. It's beginning to fog up....any one know how to get in there to clean it and re-seal it? My weather seal is going bad I believe.

That's about it for now! any help would be much appreciated!

Thanks!
Matt
