hey guys its been a while but the car has been treating me pretty good. so i was on the way back from the store this morning in my a4 when my power steering just went out in the middle of driving. the battery light and the emergency brake light also came on at the same time the steering went out. when i got back i disconnected the battery waited about 5 min and reconnected it but everything is still the same. the power steering fluid is full. i have no clue what else to look for and i would like to get an idea before i take it to a shop. thanks

 

anyone have any ideas?
