Both are dead and I was wondering if it's and easy fix, I drive a 2003 A4 Avant 3.0. I know for the front turn signal and head lights you need to remove the whole front bumper but I was hoping these would be easier since it was $93 in service to replace a $3 turn signal bulb.

 

the brake light is easy.theres a circular access panel on the inside of the trunk with a long screw holding in the fixture. take it out and the whole assembly comes out, then you just have to disconnect the wire.

the head lights are pretty easy (if you or a friend has small hands).just take off a couple pieces to get in there.

for the fog, im really not sure.ive never had to do it so maybe someone else has tips

 

fog just pop off the grills undo the hex bolts and swap the bulb. Just as simple.
