E400 "Sport Tuned"
 

What is the difference between "sport tuned" agility control on my e400 and the the regular agility control?

may be this helps?

Sport tuned just means there is more resistance from applied to them. FOr example, some cars mercedes sells has adjustable suspension, ala last few years of cla, and you can change the default resistance of the shocks; but same dual chamber technology. or the gti's dcc

Agility control is basically dual chamber dampers. Similar to these,

if not a version of this tech. Ive seen people reference this type of shock when replacing stock ones with aftermarket parts.
Basically, diff amounts of force on them react differently. its like a fluid reservoir inside of the shock, from my terrible understanding of mechanics. =D Hope that helps. In sharp handling situations, itll have diff amounts of resistnace.

i also notice when the fluid in the shocks is cold in the morning, they hit the bumpstops easier over speedbumps; but the same bumps later on at the same speed you hear nothing.
