Could someone explain me what is the idle speed and how does one understand if it is too high...?


The self-leveling suspension (LAD) as found on the "iL" models is completely unrelated to the transmission. Torque (or axle wind-up) is the reason the rear of the car is settling when you put the tranny in Drive. If the movement is excessive and/or bothersome, it may be that the idle speed is excessive. A high idle will exagerate the settling of the rearend.

Every time I shift from "D" to "N", the rear end seems auto-
matically elevate a couple of inches. I suspect my car has the SLS (hope not). If it does, is it typical for that model year for E32s? What are the pitfalls & how do I disable it? Does disabling it make sense to you guys? I remember I had it disabled it in my '88 M6 - it was a costly
proposition and I'd like to avoid it this time.

Any feedback would be appreciated.
