Hi Al,
I have an 05 volvo s-80 T6. During my last visit to the service dealer, they replaced a "Turbo boost pressure sensor". This was after a ECM code 601 - Control system boost pressure fault, signal too high....reading. Is it just my mind or it seems that the car now takes off like a jet, seems quicker accelleration, especially from a stop. What was this part....? Any comments appreciated
John
