I had to jumpstart my 96 E300 yesterday after leaving the interior light on all night. I hooked everything up the correct way and after I started my car, The Check Engine Light and the Check Engine Electronics message appeared and has stayed on. I tried unplugging the battery today thinking it would reset everything, but the light and message still comes on. Any ideas on what I screwed up by jumping my car? I'm beginning to hate these computerized diesels.
