Hi folks,
I'm trying to get the drive mode selector UI to show up on my S90 *without* having the physical hardware selector present.
I've set #057 to 03 and #452 to 01 but despite individual drive modes showing up under "My Car" in Sensus, I don't seem to have the drive mode option.
In addition, i've lost the 'Eco Mode' toggle on my main page as well as the hill ascent assist selector.
Any help here would be sincerely appreciated as I'm at a bit of a loss!
Has anyone managed to figure out what config combo will make this work on the xc90, v90 or s90?

Ive purchased a button panel to retrofit - but uncertain if it will be plug and play or require some wiring mods due to the rear seat climate control buttons. Ill post back if i get around to installing 
I'm *really* trying to avoid putting in the hardware to support this, it looks like a pain in the ass to do.
Cars with the polestar pack fitted aftermarket seem to have the drive options *without* needing the drive selector toggle hardware so I'm presuming it *can* be done. Just need to figure out how.
It works on my V60 without any button and no polestar pack. I think the issue is only on 90 series for some reason

Yeah, which is very odd indeed, i'm not 100% certain but I remember the first thing I did when I bought this car was to dive into the settings and i'm pretty sure I saw the drive mode selector in there.
I'm also thinking to buy the control that sits under the screen from an XC40. The shape seems to be exactly the same and maybe I can get the Drive Mode button to work
