P201561 and P005400 fault code messages
Hello everyone! I have a Volvo S80 2007 II (AS, 124) 2,4 D, 120W automatic, and the engine suddenly lose power during the drive. There is no smoke when I accelerate, just no power. I use a fault code OBD reader and after that erase the fault codes (P201561 and P00540) and i drive about 80 km, when the engine lose power again and fault codes reappeared. Do you think i should replace the boost pressure sensor or/and boost pressure control valve. But I don't know their position on the engine. Thanks!
