Hey, I have a 2009 DS 250 that i just bought, the battery was dead to I charged it, and when i went to start the 250, A little black box under the front right fender started to smoke up like crazy, I also have no spark, Do you know what this box is or if it could effect me not having spark? I bought a coolant temperature control unit because i thought that it was the right box but it was half the size of the box that started smoking! And info would be nice, thanks!
