I have a 1994 Mercedes E-320 Coupe with 112500 miles on it.
Today when I started the car, the check engine light came on.
I am having the head gasket replaced and the motor mounts replaced. Would either of these problems cause the light to go on?
The temp is normal and the oil pressure is good, the car doesn't seem to run any different than before the light came on. It doesn't flicker, it stays on all the time. What does this mean?
Thanks, Bill Scott
