N52B30 DISA flaps - noises??

A friend of mine lent me his diagnostics cable so I ran INPA just to look around a bit - have tons to learn with regards to diagnostics and coding, but managed to find a section that had to do with various engine components and along with Vanos there was a section for DISA flaps.

I gather this allows you to test each of the DISA flaps one at a time. Took a vid with my old point and shoot Nikon (VGA quality) of the noises that DISA Motor 1 made during this test - DISA Motor 2 was less prone to make this noise, but did a few times.

Question: is this normal or not? Battling with a rattling noise while driving which is not pinging and have ruled out as much as possible except the DISA flaps...
