The other day I had to replace a seat heater switch in my 1987 560SEL. As many of you know, this involves removing the ashtray and the black thingy which holds the horn switch and seat heater buttons. Out of curiosity I lifted the insulation which was now exposed under the ashtray and found a box that said (in four different languages) "Warning! Do Not Remove". Needless to say, I did not remove the box, however, because of the multilingual warning I am very curious as to what it could be. Anyone know?? Is it a doomsday device?
