Where's the car located? Are you in Southern California? If you are in Los Angeles I would suggest you take it to Mr. MB Motors to get the codes checked.
People on here will definitely help. Also, use the search option to find threads that pertain to this problem.
Welcome to the Shopforum and good luck with 300E's CELight.
