I have a '95 E420 with 93K Last weekend I got a Check Engine light. Today my mechanic reset it and it was Code 19. He looked it up and it said something in the "emissions system being at their limit". He was busy and I told him that I would come back later. I then looked in the archives and found numerous posts about Code 19. They all said something about a new computer.
Any help would be appreciated.
