I have a 2000 E320 W210,that will die istantly ,if put in reverse after startup in cold weather.If I start the car in the morning and let it run for 1-2 minute,its fine,if I am in the hurry and engage the reverse 10 sec after start up,will shut down,and need to be restarted and let idle for one-two minutes or so.It happends every time in the cold,around freezing temps.
