1 Like many other owners after a couple of years, the constant rattle of my glovebox was starting to drive me crazy. I started noticing it get particularly bad during the winter of 2003, but managed to live with it for several months. Finally in March 2003, I fired my first salvo by removing the hefty owner's manual from the glovebox. The reduced weight stress on the flimsy mechanism helped a lot, but it was obvious that real surgery ultimately had to be performed. Finally, in July 2003, after reading the many instructions and success stories that had been posted on the various message boards, I bit the bullet and started to work on silencing my glovebox once and for all. As I write this, I have been driving the Z3 for 3 days with its newly reinforced (and quiet!) glovebox over the rutted rural roads near my house. So far, all I hear is the motor and the stereo and I am very pleased with the results of my 3 hours of work.
Here is a summary of what I did in the hopes that it might help the many other Z3 owners suffering this auditory plague. Basically, I followed the instructions of several others, with some minor variations of my own thrown in. Unfortunately, during the intervening years all of the original instruction pages have disappeard from the interwebs and all that remains is this pdf that I luckily socked away for safe keeping. Although it was written to accompany a repair kit that was being sold on ebay, it is still relevant and you should study it thoroughly before attempting to fix your glovebox.
