Strange steering related humming noise
This is as i see it very odd, it appears as follows:
Sometimes only sometimes when it is cold wheather (like 2-15 degrees celsius below 0) a very annoying sound starts. It appers to be transmitted through the left air intake vent on top of the dashboard. And what really confuses me is that it is not rpm related, meaning the frequenzy does´nt change with engine revs. As i would expect if it is connected to power steering pump...
And even more confusing is that it stops when i turn the steering wheel or push the brake pedal!!!
Does anybody have an idea about this strange and annoing noise?
