2013 xc60 knocking sound

[Tim61988]

Hi, everyone
Apologies if this post appears in the incorrect location this is my first attempt. Where to start? So I have recently found a knocking noise coming from my drivers side whilst accelerating hard out of left hand turns, usually trying to exploit gaps in traffic.
I initially took the car to volvo who diagnosed a cv joint, the whole driveshaft was replaced including both cv joints. To my amazement the fault resurfaced after a few weeks. I don’t tend to drive like I stole it so only noticed the noise when I give it the beans whilst turning left.
I decided to take the car back to volvo who replaced the driveshaft again under warranty, and shock horror the fault is still there! So this is where my problems begin I’ve had the car on a spider ramp and inspected all bushes/joints, rod ends, shocks/coils and mountings..... absolutely nothing to report.
I am totally stumped the noise is not apparent under normal driving conditions no knocking or clicking going round roundabouts or over speed bumps/pot holes, only whilst giving it some going left at junctions.
Don’t get me wrong I know the answer is don’t give it stacks whilst driving but I really want to know what’s causing this. My only other thoughts could be a engine mount or loose brake pads but everything seems okay.
If anyone has any ideas please feel free to add you advice I would really appreciate it.

Would also like to add the the vehicle has been inspected by myself, Volvo and my local trusted garage but we are all clueless 😭
