Yesterdays ride started with me changing my bike from one up to two up ride setting. The icon on the display blinked once and that was it with no raising of the rear suspension.

From other posts regarding this, I have tried over and over to change the setting with no suspension change.

I am hoping that a trip to the dealer and a software flash will correct the problem... If not I would like to have some options as my bike is out of warranty.

Has anyone had to replace the components with aftermarket like wilbers wesa, or others, and what is the cost?

I would like to keep the ESA feature, but have options other than the OEM BMW components.
