How to know if EDC is working?

My "new to me" E92 is a month away from going out of warranty (I did get an extended though from the dealer (not BMWs extended)). I've been taking her in about every 2 weeks for little warranty fixes.

Anyways, since I've had the car, I've never noticed a real difference between the various EDC settings. Is there any concrete test to validate it's working right? The lights come on when I push the buttons, but my butt dyno just doesn't really feel much of a difference. Maybe I need to be pushing the car at track levels to notice? If it's very subtle, then maybe it's working, but if it's supposed to be night and day, I can't tell. I used to spend a lot of time on the track on a motorcycle so I'm pretty good when it comes to feeling out a suspension. Then again, I'd argue a motorcycle suspension is a lot easier to feel and notice (at speed and in corners) than a car. Any advice on how to test EDC would be appreciated.

This.

EDC may be difficult to feel on a smooth road whilst driving straight. This is due to the fact that each setting is variable and can soften when driving straight on a smooth road. It only firms up when there are direction changes or changes in load. Quickest way to test is to go over a speed bump slowly in each setting. The difference is significant.

Ok. I'll go find a speed bump. I've been changing EDC on the highway and doing some minor in lane swerves and I don't notice much change in the body roll. I'll test and report back. Thanks guys.

Minor swerves won't load the dampers up enough to feel the difference. A rough road or a speed bump is the quickest way to tell.

You can really notice the difference on concrete freeways that have a lot of seams.

Agree with all these folks, you should notice a difference between the settings. I would have them checked.
