My RS6 crapped the bed with my wife driving. Symptoms she described are/were: Erratic rattling noise - don't know if it was tied to RPM's. Fluid out the bottom lined up with Steering Wheel. And steering became very difficult.
So, we went to the site of the event and found the fluid had leaked for a half mile from where she first started feeling something up, to where she eventually came to rest. She doesn't really know when the rattling noise started 'cause she had the radio on nearly until she stopped.
1. Is it the Power Steering Pump?
2. If so, do we replace with rebuild OEM or new? And where is it located / How much should labor cost?
3. If it something other than the Power Steering Pump, then what is your best guess? Hose? If so, how would a split hose cause noise?
Anyway, I'm welcoming any advice and opinions. Thank You.
