Hi there,

I have a low whining sound whenever the car is running and it speeds up when i accelerate. The oil separator was just replaced and there is no check engine light. Everything looks fine when i hook up the OBD2 tester, except for an INC on the catalyst monitor. This is my first volvo so i am not sure of the "normal" sounds it may make. Any suggestions as to what this could be?

Thanks in advance!

Is the car moving in the above description?

It could be a few different things. The first thing I would check would be the level of power steering fluid I had in the PS unit.

You can open the hood and try to locate the source of the noise with someone slowly increasing the rev of the engine. Listening through a long screwdriver as you touch different part of the non-moving parts will let you hear what is going on in that area of the engine.
