Easy as to check, start it and remove the oil cap, if pcv gone it will stop squealing and have lots of vacuum.
My old 2010 v50 needed pcv changed around 70k, and my 08 v50 is still on its standard pcv diaphragm.
The fuel pressure sensor went on both of them, and on both it eventually threw a check eng light with codes, cheap obd and phone app on mine could display logged fuel pressure.
