Okay, so it is not some made up toxic sludge that eats the inhabitants of the earth rather it does something that is super cool which is to SILENCE the ringy- dingy "your seatbelt is not not latched" sound coming from the depths of your dash when you drop your gym bag or laptop bag on your passenger seat on your way to work. One day I counted the ding-ding-ding's and I either lost conciousness or was hypnotized by the time I got to to 60 of them...and if you move the bag or turn a corner and the weight shifts, it starts over again....and again. For Gen 2 MINI's that have the built in annoyance feature that cannot be turned off until now.... Make it all go away with the Chimex: http://www.outmotoring.com/mini-coop...top_chime.html
