I had that issue. Checked all engine brake pistons and one of them was loose .50k miles later works perfect.
Volvo D13A pre euro 3 was without EGR but I agree it's going to be really expensive modification to do.

I have same vibration on engine brake stage 3. My mechanic sad that my injectors are going bad. I know it does not sound logic but on stage 3...
Why not to change with Legacy Gold or other great aftermarket seats?
My friend has 1.9 million on his D12 engine still running good. He changed injector cups and turbo. No overhaul yet.
