Posted this in another thread, though it might get more views on its own:

Well, I cant open my damn trunk to even see if my just my brakelight bulbs are bad. I've done the turn the key counter clockwise trick and opening from inside latch, still doesnt work. Using the key in the lock doesnt work either .... sigh.

S4 Vert BTW.

 

try pushing down on the trunck and then turning the key or pulling the latch. if that doesnt work you may have to take it to a dealer

 

Yeah, tried that, damn thing still won't open.
