In August of 08 my 2004. 5(new body style) Volvo S40 t5's engine began to make a high screeching noise at idle and the check engine light came on. It had 61,000miles and I brought it to the dealership where they diagnosed that it needed a new oil trap. The problem has not recurred. My wife's 05 S40 t5 has 58,000miles and the same problem has occurred in her's. There must be an issue with this vehicle.
