X5 M, EDC Button

[ncmoore12]

Hello all,

I am new to this 2013 X5 M and my roommate and I were trying to figure out the EDC (Electronic Damping Control). When the button is pressed (Light Green) what does it do? Are you effectively riding in a sportier suspension setup (increasing/decreasing dampening for better handling, compromising on comfort)? Just curious and can't seem to find any more information on it. Also how much does everyone use it? I think it rides smoother with it off (no depressed), but still can't tell.

Thanks!

Like all E70 X5 models, the X5 M utilizes a rack-and-pinion steering system with an overall ratio of 19.5:1 and Servotronic variable power assistance, which constantly varies the amount of assist based on vehicle speed. However, the Servotronic system has been specifically tuned by BMW M. In addition, two different parameters for the overall level of assist are offered and these are linked to the Electronic Damping Control (EDC) modes: Greater steering assistance is given in EDC Normal mode and less steering assistance is provided in EDC Sport mode. (These settings can also be programmed as an MDrive preference.)" - Quote from link above, thanks DeeO, I read this before but I think I forgot about it.

So it really affects the steering and I assume the button being depressed is the EDC Sport mode then.

Steering as well as suspension.

The effect of EDC was was noticeable for me when driving on the highway with that has twists. Also after driving the X5M for a month straight then going to my analog Z3M.

Here is a general summary of EDC technology
from BMW (below)...as well as a video found by typing "BMW EDC YouTube":

Electronic Damper Control (EDC) automatically or manually adjusts each damper to suit the driving conditions meaning you enjoy outstanding comfort along with the best in BMW on-road safety. EDC reduces variations in wheel load, ensures tyres have excellent traction and counteracts bodyshell movement regardless of the weight your automobile may be carrying or the state of the road's surface.

Sensors constantly monitor all factors influencing the vehicle's behaviour and occupants' comfort, in order to precisely adjust the damper control. In a fraction of a second, the signals are analysed by the EDC microprocessor and orders are sent to the actuators on the shock absorbers, which, with the help of magnetic valves, are variably adjusted to provide optimal suspension. Thanks to Electronic Damper Control, the tendency for the nose to dip when braking is practically eliminated. The influence of potholes and unevenness on the road surface is reduced to minimum.

In addition to increased driving comfort and improved roll characteristics on the tyres, EDC also contributes to vehicle stability and safety. By reducing the nose's tendency to dip when braking and improving the tyre traction, EDC shortens the braking distance when braking heavily. The damper adjustment means that even when braking with ABS the vehicle chassis remains upright on the road and all four wheels have the largest possible contact to the surface.

The Driving Experience Control switch with ECO PRO lets the driver choose between various programs (like COMFORT, NORMAL, SPORT or SPORT+) and adjust the suspension to suit his individual needs.

when you turn on EDC car feels less like a whale in short..

Thanks for all the responses!
