rear nearside suspension clunk

BRRF:

Has anyone experience of a clunk coming from the rear nearside corner everytime you hit a small pothole or depression in the typical UK road surface
It feels like the damper is not working but the car sits properly on the road & no leakage or obvious signs of issues looking under the car

Evoque has done 45k miles.
Never off-roaded
The haldex pump was replaced appx last September - & Its done about 5k miles since HP change
Thanks
