Hello all, I have a 2000 323 ci steptronic and was wondering what is exactly the SD mode. Do I have to shift or does the car do it manually? I'm a newbie so any feedback would be greatly appreciated. Thanks
BMW mapped shift points are available in the "D" mode.
A limited amount of "learning" happens in "SD" mode, where the electronics from the motor, transmission and other various sensors have some ability to figure out how you are driving. The shift points are changed from "D" mode to slightly more aggressive.
In "M" mode, the gear is somewhat in your control. Attempt to shift too early, and it won't. Attempt to downshift into too low a gear too early and it won't. Hit the rev. limiter in this mode, and it will shift for you, even though it's supposedly in the "manual" mode.
To know which mode you are in look at the display between your tach and speedo. Pulling the gear shift straight back into drive from park as in any type of automatic, you'll see "D" displayed.
Move the leaver to the left from "D" and "SD" will appear. Once in "SD", move the leaver up or down and the display will change from "SD" to "M". Once in "M" you'll be able to move to next gear by tapping the leaver up to "M1, M2, M3, M4, M5".
Hope this helps.
