Volvo Repair Questions? Ask a Mechanic for Answers ASAP
I would suggest that you take the vehicle to your local Volvo Dealer where it can be diagnosed accuratly and probably repaired free of charge seeing as it will still be under warranty!
The slight problem with noises is that it could be anything! Could be a heat sheild, a brake backplate or even something you have picked up down the road wrapped around your hub making a noise!
Unfortunatly noises are impossible to diagnose over a computer! You need to hear them and look at the vehicle for an accurate diagnosis.
