ᐅ Cracks in the facade 7 years after painting

Would it make sense to remove the plaster in that area to check if the crack continues underneath?

So, I just checked the garage. You have to look closely to find the cracks when the sunlight hits them, they're that small. I would estimate about 1-2 mm (0.04-0.08 inches). Just barely visible on the plaster. So, these should be negligible, right?

Here is a close-up image.
Does this help to assess it better?

Tap on the cracks to check if there are any hollow spaces underneath.

We have an external thermal insulation composite system underneath, and I believe there is polystyrene insulation.

In any case, when I tap on the facade with my hand, the whole surface sounds hollow.

I looked it up, and if I understand correctly, this is called ETICS (external thermal insulation composite system), and is it normal for it to sound hollow here?

Is this a prefabricated house? I'm having trouble explaining the vertical cracks.

I looked through the documents. It’s a solid timber-framed house. That’s what was stated in the real estate listing.
