Flexi sorted 90% of the problem.
There is a very light vibration still, felt through the steering, but this is an old school diesel, and I don't think it is out of the ordinary.
If I want it fully vibration free, I think the only thing that will fix that is a new injection pump, but the old one still works just fine and car goes very well after tinkering with the ECU and upping the boost to 1.25 bar
But really, now the vibration is like any other diesel.
The main issues were:
1. Lack of flexi on the exhaust and exhaust going into a resonance.
2. Worn out engine mounts.
3. Worn exhaust mounts.
Flexi made the biggest difference. The exhaust has been repaired and welded on in the past, that might also be a contributing factor.
