Hello.
I have an e46 touring with m57 150kw engine.
The problem is that, ive changed the thermostat and coolant couple days ago, aswell with couple vacuum hoses.
And after doing the jobs and going home i noticed engine vibration, especially can be noticed when sitting in the cabin. It only happens when idling at the stoplight. Im not entirely sure, but the car seems to have less power, and feels kinda stiff. Other than that, the power loose isnt big, it still goes like crazy.

Engine mounts were replaced in the near past, so it doesnt seem like it.

When clutch is depressed the vibrations almost dissapear.

Please help guys, how to thermostat change could be related? Maybe ive connected the egr or turbo lines bad, what could it be...?

Thanks in advance.

When you depress the clutch you are disengaging the engine from the transmission, your problem may be on the drive end. Have you tried coasting in neutral to a stop to see what happens, and at what point something does happen?
