How to know if EDC is working?

djseto · 10-15-2012, 08:38 PM

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.

The EDC is very noticeable..go over some bumps in full stiff..then go over the same bumps in soft..you will notice..(if its working)

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.
