Silly question but what does "S" and "W" mean on the gear box
I heard "S" is Summer and "W" is Winter
I find W more economical than S so should I just leave it in W?
On my previous E300 "S" was sport and "E" Economy
Also has an effect on reverse which has two gears (722.6 gearbox). Can't remember which way round but I think W makes it reverse slower and S faster. Try it out, select reverse and you can feel it creep at different speeds between settings.
W - winter
S - standard
Winter mode it pulls from 3rd
Standard from 2nd
I think it varies too if w140 is 4 speed (pre facelift) or 5 speed (facelift)
Too pull from first lever need to go to 1
As far as I remember correctly
