Hello,
Sorry for the delayed reply.
It is not easy to say what exactly went wrong due to intermittent nature of the symptoms. Most likely the gear selector module was not working at low temperatures. In this case, selector lever position is not clear to electronics and starter is blocked.
There should be some fault codes in transmission and selector lever control units to confirm this. These codes can be read out with Star Diagnosis computer, which some of the independent MB shops have besides the dealers.
