2003 Mercedes Benz C230 4 cyl Two Wheel Drive Automatic 59900 miles
My check engine light came on. The Mercedes dealer ran a diagnostic and indicated the thermostat needed to be changed. I changed it myself and now can't figure out how to clear the CEL so I can see if that was the true problem. How do you clear a check engine light.
