Dreaded WG rattle (I think)
Noticed on cold starts I had some rattling happening, it only does it around eco/comfort mode too presumably due to load (sports revving higher)
https://www.youtube.com/shorts/YnnOjNYozsI It's super inconsistent and only does it on extremely shallow revs from time to time. IIRC there's no real fix for this right; the WG flapper isn't serviceable?

Providing this is a WG flapper rattle issue, can I just adjust the linkage rod? I had a look today and noticed it was threaded so I'm guessing adjustments can be made?
Noise is now audible when pulling away in low gears.

I think the bolt on the rod sets the opening of the flap. The flap itself is on a centre spindle and it's that area that wears and causes the rattle. Adjusting the rod is the fix.

I also have ISTA so I might try run the adjustment test to see if it notices any play.
