Power steering system completely failed on numerous occasions. 18 months ago, power steering failed and whole power-steering system was replaced by dealer under warranty. 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 related to vehicle motion. I called Audi of America, and they say there is little that can be done, yet they claim they'll talk to the dealer and get back to me. Conversation did not sound hopeful, and when the proposed solution from the dealer was to replace the exact same module that was replaced 18 months ago, I suspect something else is going on.
