SL55/63/65/R230 AMG: Yellow check engine light came on....won't go off.
I checked the gas cap...it's on tight. The car is running smooth.....has mileage seems fine. I went back home last night....and have been driving car somewhat today....same thing, orange CEL stays on....I drove maybe 25 miles today.
Any ideas? Everything seems fine....and it's odd that light went on after I almost drove on it empty.
It is possible that you sucked some junk from the bottom of the tank and the code is something about the fuel system.
Or it could be a coincidence and your cel is not related to your running to empty.
I had my front pads and rotors done last night and they must have reset the code as the check engine light wasn't on when I picked car up. I drove 200 miles today and last night and it still hasn't come back on....so it must have been due to the almost empty tank the other day and just needing the light to be reset.
