D3 airbag exhausting?

I've got a D3 on air suspension that sounds as though the right hand front air suspension is 'exhausting' or making a rubbing/graunching noise when taking a left hand bend. The amber 'yaw' light comes on briefly but immediately goes out when straight ahead. The car comes up from access height quick enough and otherwise drives, brakes & steers really well. It's a strange fault that I can't trace on my Lynx diagnostic. Would really appreciate any help.

Check your wheel bearing, it's a common fault on these.

Thanks Owl, I've got both lower wishbones to replace so I'll have a good look at the same time
