Hi Emilio
I am pretty sure Tiemo catched it.
After i read this below I remembered the noise and behaviour in the Videos. Now I remenber why I thought I did hear this noise somewhere before.I had the same 20 years ago as my Vibration Absorber of my ACL was broken.
The Rubber inside which should keep the inner and outer Part together lost his connection to the metal parts.You never should try to hold or fix the outer part for fixing or unfixing the central screw which needs 440nm Torque. You need the tooling which connects to the inner part. Perhaps someone did not use the correct tooling in the past while changing the drive belt and now the absorber is broken.

Hello Emilio,
if the enginge itself shakes, regardless to the gears, the problem might be the cooling fan, viscoclutch, or the vibration absorber with the v-belts the cooling fan is mounted on. There might be an unbalance, perhaps due to aged polymer in the absorber. You can try grabbing the fan at one of its blades (but not break it!) and move it forth and back. If there is visible clearance, this should be examinated closer.
Annother possibility might be a bad injector that reduces power of one cylinder, so the engine is not running smoothly. This would not occur driving downhill with throttle lift-off.
Ciao,
Tiemo
