Glove Box Door
Hi, You have to replace the whole glovebox, seems a common problem on A2's, I recently replaced mine, it was easy enough, but the cost is £165 inc of VAT, only available from Audi. It takes about 20 mins to take out all the screws, then about 10 mins to replace. There are two screws below under the dash, the one on the left is tricky. You will need a magnetic screwdriver, to hold the screw on the screwdriver, push the trim back and get that screw in. If you drop it, you will lose the screw behind the left footwell panel. That would mean either another screw or take more panelling off to find it. Its an easy job to do. There are about 4 screws on top/inside the glovebox. You will need a small handled screwdriver for some of these, as it needs to fit inside the glovebox. (Halfords sell these for £2.00).
hope that helps. Good luck.
