Not to long ago I had to drive through some quite deep water. Now apart from loosing my front reg plate I've gain a weird whirring noise coming from the rear left side of the car. When at slow speed it's not there but at higher speed becomes more noticeable. I've had the wheel bearings checked and they were ok and also inspected the rear brakes for debris. So was just wondering if anyone else had any ideas?

thanks in advance

You have probably ripped one of the plastic underbody shields or the exhaust heat shield loose and it is flapping/vibrating as the airflow increases under the car.
