Bought a 2013 sept sdv6 autobiography dynamic and the suspension is very bounce.
I’ve had rrs sport before so I know what they should drive like and this is terrible.

Any ideas on what it could be.
Mileage is 75k

Struts or height sensor maybe

Air suspension goes up and down fine.

Any help will be appreciated [/b]

What size wheels and tyres you running? ===========================================
2012 Range Rover Sport Autobiography 3.0 SDV6 8 speed Automatic
Indus Silver with Hockenheim premium two-tone leather Ebony/Lunar,

275/45/22

No fault lights

OK so they should be 275/40 r22 (2.3-2.5 psi)
275/45 is for 21" rims

that said your only 5% taller side wall .6 of an inch,
so I don't think that's your issue
But you speed is possibly higher than your speedo is showing..
