A4 owners - do this today and save yourself over £150!
The glovebox hinge on A4's have a damper to allow the lid to drop gently. Over time these get stiff and they WILL break the hinge. For ages I've been thinking "Soon I must lubricate that damper" - but I left it too late and the hinge broke :banghead:
This will take you one minute at most!
Pop the end of the dashboard on the passenger side and you will see the damper. Lubricate the barrel with a silicon type lubricant and replace. Save yourself the griefy glove box fix!
Credit to Marc1 for the following: It is possible to remove the damper and split it and take out the O ring which provides the damping. The glovebox will still work fine but the damper will not be stressing the weak hinge.
