Metallic noise during regen braking

New noise for my Jan 2015 S60. Noticed a whine between 42-53 mph (suspect the resonance just changes above that (and below I guess) - wife noticed it first, now I can always hear it at those speeds. Coincided with a 1 in 3 occurrence of a metallic sound as regen cuts in - seems to happen more when weather is warm (not whether car is on a long or short run).

Sounds somewhat like when you have something caught in a brake caliper, 'light' metallic sound (not heavy grinding). Have heard the same noise on approach to ramps it auto-raises for, but I suspect that is regen too - as if I keep any pressure on the accelerator, I don't hear it.

Anyone had these symptoms? Obviously going to take it SC (especially as passenger door handle stopped presenting tonight) - but keen to see what people know before talking with them about it.

i noticed that the other day when going up on a very steep hill and let go the accelerator to brake for traffic.
however, at the same time the regen curve on my display turned yellow with a maintenance icon next to it. went away as soon i came down to a flat ground.
went above the same hill to see if i can reproduce, but didnt happen. that yellow regen curve thingy went away too !

Do you have the air suspension? It makes a very mechanical sound. It's automatically self leveling so it can be triggered by braking, weight shift on hills, etc.
