Okay, my car runs great warm. Trying to get it started most days below 40 degrees Ferenheight; it has taken between 10 min, to 24 hours of cranking on my poor starter. We have checked most sensors, and vacuum lines, but I can tell there is something we are missing. We both have been mechanics (my boyfriend more than I), so we know what to look for, for the most part. I guess I am looking for some insight from a person who has history with these lovely Mercedes Benzs. Any help would be greatly appreciated.
