Wabbajack your a wealth of info so I hate to say it but Tango is correct here. DHP is an option you pay for with any configuration including the Msport in the US. If you have DHP on your X3 I guarantee you that you paid for it.
DHP gives you on the fly dampeners that like Tango states is more performance oriented. The snowmobile industry also puts electro dampeners on many of their higher performance sleds. They make a big difference but you gotta pay to play because the the technology adds cost, complexity and warranty factors.
BMW would be wise to tweak their online configurator because the whole DHP/sport suspension delete issue has been beat to death in every forum.
