When the check engine comes on my 140 with the 104 engine at 65K miles, I found the problem was the engine wire harness insulation were broken, cause the wires to tough each other at the thermostat housing. After I separated the wires, reset by disconnect the battery. The check engine goes away.

MB replaced the wire harness under warranty, I paid for labor.
