You drove 60 some miles from the first sign on to death. Electical things die mostly suddenly. Mechanical parts not so much. Computers are weird. Best bet is the OBD2 plug. There will be a code. The SIS was on telling you something. On Feb 17, 2015 2:33 PM, "Donald Snook via Mercedes" <mercedes@okiebenz.com> wrote:
