Defo worth checking out if its the injectors causing that knock....
My current DD W201 190D 2.5, I was convinced had a rod or piston-slap type knock, until I replaced the Injectors--its done 174K, so I thought it was about time.....
(It still has a hydraulic tappet/lifter knock when cold though....
)
My original old 300D OM-617 had a 'knock'....More of a 'nunk' type noise ,but that was just sheer old age and piston-slap at 350K miles. The engine was otherwise really quiet and smooth--Just annoying that noise....
It never got any worse during the near 100K I put on it, and will still run well (If it were in a car that is!)
