Hi All Car out of warranty now so thinking of lowering it. It's a 2016 8v 150tdi quattro with drive select. As I understand it drive select stiffens or softens the suspension slightly among other things. As it's a bit wallowy in even the slightest corners, I have been planning to lower it with uprated springs for a while but it seems also changing the struts can improve road holding so I am now considering changing the springs and struts. How does the drive select work to stiffen the suspension? Does it act directly on the struts? Would I lose the DS functionality if I replace the struts?
