Drivers door rattle / knocking

When I go over uneven surfaces I get a knock from inside the drivers door. It sounds like something may be loose? Anyone had this or any ideas. It is a 2018 XC90 R Design
I had a similar issue
It turned out to be the door pocket LED light strip was out of place and needed a push to click back in correctly.

XC90 T6 R-Design 2018 second batch mfd date Apr-18 US specs.
