Avensis T25 D-Cat strange engine vibration

[Nicku]

Hi guys,

Me again, with another ''problem'' regar din my 2006 avensis 2.2 D-Cat... at 2000 RPM until 2600 rpm the engine vivrate, shaking admormally. the problem started about 2 months ago. No power lose no light in the dashboard, no nothing. What I noticed is that when the engine is cold the vibrations are at minimum, they intensify when the engine is in normal functional parameters.

From where can I start the investigation?

 

regards

Nik

Another forum member had to put some vibration damping around the seam of the air filter box. However, if the vibrations are very strong, it would likely be a mechanical problem, think engine or gearbox mounts and the like.

It s not the air filter box. 😕😕

The vibrations are very strong in 2000-2600 rpm range.  When I lift the foot from the acceleration ( in  2000-2600 range)  the vibrations dissapear ; so... i belive no gearbox problems.
