Hey,
I did this install sunday on my new A4. It was really difficult to remove the sidemarkers from the outside- I tried for a while using a plastic knife, but I was worried about scratching the paint. I wound up unscrewing the two torx screws in the front wheel well. I pulled the cover back, fished around with my hand to feel the inside of the side marker, then put a screwdriver in there and just popped it out. You have to give it some oomph to get it out, its really in there!!
Once you get the old sidemarker out, installing the new ones are easy- you just pop them in.
Hope this helps- if needed i can snap some pics for you tomorrow.
