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.

Disconnecting the battery does not clear stored fault codes from the memory. Some codes will clear themselves after a certain number of drive cycles with no failure, but some will not. Try taking it to AutoZone and see if they will clear the codes for you. They should do it for free.
