The audi sq 5 loses power steering if the rack/pinion power steering unit is exposed to water. this does not refer to flooding or submerged car audi considers weather an outside influence and does not honor the warranty the car retains full propulsion but is impossible to steer the electrical mechanism on the power steering is dangerously exposed , and apparently not weather proof i made a left hand turn in a heavy rain storm up the apron of a driveway to a parking lot. i drove the car 100-150 feet to a secure spot to wait out a heavy houston rainstorm . the dashboard indicator came on signalling loss of power steering as the car sat in the spot for over 1 minute i assume the water i pushed up in front of me as i went up the apron got under the car and into the mechanism the car was never stationary in any deep water, and never in water deeper than 3 inches this is a safety issue as the car maintained full proplusion
