I've got a 1995 e320 cabriolet with about 130K miles, and my engine light went on. My ODB2 unit only goes down to 1996 vehicles. Is there a way to read the codes? Is there a way to reset it?

 

yes,there is a little black box on the right by a firewall,take the plastic lid of and push the little button,lights will start flashing,you must remember from wich number and how many time the light will flash,afer that example 8 flashes on nr 6 means some sort of troble,you must be able to figure out the codes.
good luck
