Step by step instructions on how I disassembled my glove box and repaired the broken hinge on my 2004 Audi A4 B6 Quattro wagon.
I purchased a kit on e-bay, simply search for "Audi A4 glove box hinge kit", there are a few different kits ranging from $5-$30, I'd suggest the $30 kit.
Follow these instructions at your own risk, I am simply documenting my own DIY fixes.
