So a few years ago a tree fell on the back end of my 01 audi a4 1.8 turbo on the side where the gas cap is. I took it to a body shop and ever since they had it the key fob will lock and unlock the doors but the alarm wont set, the interior lights dont come on when the key is removed from the ignition, the interior door lock will only unlock the doors, not lock them. What is up? I cant seem to figure it out and I cant justify paying $125 for a dude to just look at it.
