the check engine light was on when I bought my c240 from an insurance auction. The car drives very good. My modest OBD scanner shows codes p0306, c0300, p1503, p0603, and p1415. After I drove it for less than 20 miles, the check engine light disappeared on the dash. I scanned the car again, the codes still shows in the scanner.
