1st Question - Yes the Bollards in the
Seat are supposed to activate/move on the Drivers
seat as soon as SPORT mode is Selected, if your's is not doing so then I'd be heading straight back to the dealer and asking why.. maybe try driving off in Comfort and then once you are moving select SPORTS Mode, it might be that you are selecting sport mode before driving off or getting comfy in the
seat and not realizing that the
seat has actually already moved? It still catches me out every now and then.
I have found that the "Bollards" do actually move in & out when you move the lever which is on the side of the round knob where you have the
seat controls. They certainly do not move when the knob is turned to activate Sport. I cannot find any reference in the manual either.
Maybe on later models they changed it so you can manually set it up to be more permanent irrespective of what mode you are in.
