I thought, or should I say, only noticed it when I was steering whilst in motion. But it made a simular noise when stationary and turning the steering wheel. Checked the Power steering fluid level and that seems ok. I was convinced it was the brakes up until this afternoon when it did it stationary.... :duh:
Looking at this and your first post I'd say it was your power steering pump working if there is a whine as well. I bet it's worse when stationary on full lock. If it is this take a look at your PAS fluid, if it''s more grey than red might be worth getting it changed.
Its the Supercharger that whines...(and the Mrs) I've checked the fluid and the level looks ok. Im just hoping when the weather temp picks up I can do the brakes and maybe cure this.
