After I took the first video, I rebuilt the injectors by taking them apart, soaking them in parts cleaner, replaced the nozzles (Monarch, made in Germany) and put back together. Also replaced both fuel filters and the return lines, which were soaked with fuel. Still knocks.
This sounds like bad timing...maybe the pump is a bit late.

You have a little injector nailing...but if your nozzles are new give them a few hundred miles to seat in. If it still nails, check your IP timing.
I got nozzles for VW and Mercedes diesels from
HessianImports @ BellSouth -dot - NET.
BEST price I could find and they work like a charm.

replace your motor mounts, its sounds strange but it works.
