2006 C280 4 matic. CEL came on but scanner does not detect any codes. I tried my scanner, one at Autozone and one at Advance Auto and none detected any codes. I located the fuse for the Data Link circuit and the fuse was OK. According to another site, the fuse location is #62 located in the fuse box in the engine bay on the driver's side up against the firewall under a couple black plastic covers. Is there another fuse or something else I am missing to solve this problem. Thanks for looking into this. David P.
