Car was parked outside in stowe, vt when temp dropped to -13. Able to back out of hotel parking space but noticed steering was stiff. Once onto the street, lost power steering completely! using all my strength, I could barely steer the car over to the side of the street. Stayed in the car, running with the heat on, for about 15 minutes while we arranged for a tow. When I turned the car off and then on again (my wife's suggestion) the power steering came back! we drove all the way back to MA without a problem. Three days later, my local Audi dealer checked out the car with their computer and only found the record of the incident but no cause and everything looked good otherwise. It hasn't happened again, but it hasn't been that cold on the cape.
