2010 xc60 struts

[Webpirate]

Hello all,

Hoping to get some information from those in the know.

I'm looking to replace my struts soon and when pricing out I keep running into the question that I don't know the answer to.
I know I have "Active chasis" because i have the "comfort sport advanced" button but one of the other options for struts is "with self levelling"..
My question is,
How do I know if I have self leveling? I have an an AUTEL obd2 reader that reads all the modules and under suspension there is nothing about leveling. There is voltage readings for each corner though.
