Airbag light / circuit now reset. Got myself a code reader / fault reset tool.

Hi. It sounds from your description as though you are talking about the auxilliary (air con, water pump etc) drive belt tensioner pulley.
There is a test you can do. Make a note of how the belt is routed and then remove it. Then run the engine for a short while. If the noise has gone then there is a fair chance that it is the pulley bearing. If you spin it whilst it hasn't got the belt on it may also sound "rough".
The pulley is fairly easy to remove and there is a grease retaining seal that you can carefully prise off and then repack the bearing with clean grease and press the seal back home.
Hope that helps
Alternatively you can buy new or a known good secondhand.
