S80 D5 2008 cold engine knocking noise
Hi all, recently I experience this weird noise when starting my S80 D5 2008. Only happens when engine is cold, both idling and driving at low RPMs. When engine gets warmer, it is gone. No warnings or anything like that on the dashboard.
On separate note, today I realised that air intake hose (not sure what is it for, maybe intercooler), more specifically a part that leads to pcv system is broken. Would that cause it?
Any advice is welcome.
