Can anyone help?
My S420 Benz 1996, failed the smog test twice and my mechanic has informed me that he had checked all possible reasons the will cause the car to fail the smog test . The print of the test shows "Not Ready" for all he 5 points. Today my mechanic told me that the dealer recommended that I'll replace the computer in my car inorder to pass the test. Is there anything else that can be done? Any comments.
Thanks, Shimon
