I notice it equally, well slightly louder on the offside but I'm sat there so I'm guessing its the same noise on both sides and yeah that is the noise it makes you described it really well!

Its when the speed bump flattens out but I've noticed it only does it on speed bumps that are quite angled, if it is a smooth curve back to the normal part of the road it doesn't make a noise.

So I'm guessing this is just a character trait of Volvo air suspension then - do you get the same noise in all modes?

Might try it in a different mode other than Power/Dynamic and see what it does!
