Hi all, 2002 A4 1.8t Quattro

I just installed the driver side side view mirror. Now I have to install the driver side front fender. Do I have to remove the bumper in order to remove the fender? Also, how do I remove the door trim, under the door ledge ( rocker panels)? There are T27 torque bolts under the trim but they don't loosen. They just spin. Do I yank the trim off? I have to get the trim off so I can access the bolts at the bottom of the front fender.

Thanks in advance!
