Hello, this is my first post so apologies if this has been asked before - I have looked but could not quite find the same question anywhere. I have an E350 Sport Estate (diesal), 2010. It has a 'C' and an 'S' and an 'M' mode. I have been trying both the C and the M modes in the current slippery conditions, and am struggling for traction and control in both. I know I should turn off the ESP when starting. But I have also been trying to start the car in 2nd gear, by using the M button. Except it does not seem to let me do this: it always starts in 1st! Similarly, I have tried to select a lower gear earlier via the M button, when for example trying to go up a slippery hill. Again, the engine often seems to stay in the gear it is already in (say 3rd) when I want it to go into 4th. Is this simply because there is some kind of limiter, stopping me from selecting a gear that is too low? In short, should I drive using the C, or the M? Frankly, both are scaring me to death :Oops: Finally, I have heard it said that a very simple solution is to place heavy bags of sand into the boot. Is this true? Many thanks!
