Correct its the link between the swirl motor and swirl throttles. The ECM will have logged DTCs for swirl system performance and mass air flow (as the engine is not seeing the expected air flow when the swirl system is attempting to operate).
You will be able to fit a replacement link however Volvo have re-designed the link/swirl throttles to prevent the failure occuring again.
After the link is replaced or the new type fitted (this requires the injectors removing & top engine cover/cam cover removing to replace) the DTCs will need erasing and ideally the Swirl motor/system re-calabrating.
Volvo also have a mod available which involves drilling the link and fitting a metal pin/clip. This is a very fiddley process ond oftern comes off!
