2014 AUDI S6 Steering Problems

I was driving hit a puddle of water, then all the sudden my power steering went out. I took it in to get looked at, and I'm being told it will cost several thousand dollars to fix the power steering. In addition, this vehicle has air in the suspension, but it now makes sounds when it lifts and takes a longer period of time to lift than normal. Something is effected in my suspension, as well. My vehicle only has 67,689 miles on it, and it should not be having power steering problems from driving through a puddle of water. Lastly, after calling in to Audi, they did a search for the warranty, and Audi did add an extended warranty on the power steering of 125,000 miles or 10 years, which ever occurs first. This means they know about the power steering issue, and with my car being just over...

NOW, 1 MONTH AGO, POWER STEERING COMPLETELY FAILED AGAIN, FOR TWO DAYS, AND THEN RESUMED NORMAL OPERATION ONCE I LEFT SNOW COUNTY (I DON'T KNOW IF THE COLD HAD ANYTHING TO DO WITH IT, DESPITE THE FACT THAT THE SYSTEM IS ELECTRIC-ASSISTED, NOT HYDRAULIC). I TOOK VEHICLE TO MY LOCAL DEALER THAT REPLACED POWER STEERING SYSTEM 18 MONTHS AGO, AND NOW THEY CLAIM THERE IS NOTHING WRONG - BUT THEY SUGGESTED I COULD REPLACE THE WHOLE POWER STEERING MODULE AGAIN FOR $5700, SINCE THE CAR IS NO LONGER UNDER WARRANTY. ON BOTH OCCASIONS, POWER STEERING FAILED, THEN RESUMED, AND THEN FAILED IN A REPEATED MANNER EVERY 30 SECONDS OR SO, WHILE ALSO SOMETIMES REMAINING BROKEN FOR MINUTES AT A TIME. BEHAVIOR DID NOT SEEM TO BE...
