This may be answered on here already, but I couldn't find it. On a b6 3.0 should there be any visible flow in the PS reservoir at idle? Thanks.

 

Not really. But only if there is air in the system will you see the
air bubbles. But when the system is perfect you won't even recognise a simple movement unless someone is moving the steering wheel from left to right. Cheers

 

Thanks! I was hoping to hear that!
