I love driving this volvo, I love it more than the GTI I used to own.
BUT the severity of the damage done from an engineering defect with the oil separator has me question volvo's reliability.
Here's what to do if this happens to you.
If you hear a hum that progressively gets louder as the engine warms up, NOT a belt squeal.
STOP the car and IMMEDIATELY shut the engine off.
Have the car towed to your mechanic or dealership.
If you do not stop the car immediately you'll ruin the seals in your engine, the crankshaft, timing belt and possibly other parts.
