I've invited you several times before to share your story and information with the transition chassis/year. Posts #12 & #14 of this thread show it. It's good to learn from your specific XC90.
Here I link the source. Part #44 on Volvo's own parts list shows the chassis number cut-off, according to Volvo (China might be different). https://www.volvopartswebstore.com/...=7095&ukey_driveLine=505&ukey_trimLevel=24666 Whence why I invited you to share your specific case of the transition in fluids.
Edit: Adding Volvo currently states chassis cut-off is #568001
