The nylon sliding shoes look very un-worn on that tensioner. It could be the light but the colour of them looks slightly different to the original shoes that came out of my S8 at around 110k miles.
How does the chain wear track compare between the faulty tensioner and the working one? Also pad colour the same?
Just wondering on the off chance its a non-OEM tensioner. Or maybe just the shoes were swapped.
Definitely missing a small fine-mesh filter in that oblong hole.
I forgot how the mechanism works exactly, there is a locking pin somewhere that is released by oil pressure, it could be the lower pad that's locked until oil pressure releases it. There is a 40V engine study guide somewhere perhaps on a sticky.
Both my old tensioners are locked on the bottom pad, free moving top tensioner on a spring, they were working when replaced (replaced preventatively)
