Question Asked: What does service code AO indicate?
February 18, 2011, 12:27 PM
I get a service code of AO on my instrument cluster. I know A means the oil and filter are due for a change, but Mercedes would not tell me what the "O" service code means. Check brake pads and rotors, change brake fluid perhaps????
