Is it possible to animate a collision mesh? I've seen the AnimMesh4 example, there you bind the mesh to the animated one and use this to send out particles. Is there a similar way but then for a collider?

Maybe yes, if by an animated "collider" you mean a destructible mesh, depends on the engine you are using:

In PopcornFX Editor you'll need a recomputed animation.

In Unreal Engine 4, it should work with a destructible mesh setuped as an Attribute Sampler Skinned Mesh: https://wiki.popcornfx.com/index.php/UE4/Class_PopcornFXAttributeSampler

In Unity, Attribute Samplers Skinned Meshes should work, but I don't think we ever tested destructible mesh in Unity.

Sadly I don't want a destructible mesh.

I'm currently making a rain effect on a windshield, and I want to animate the collision mesh (the wiper).
You can use animated meshes but the collision mesh can't. I've read about using MeshId's and do it this way?
But this doesn't suffice my need.
