I had the same issue back in November. And the power steering was gone...and it took a lot of strength to steer the car. Took it to the dealer and they said its a false alarm and performed a reset. I had it come up couple of times a week until mid Dec where it wouldn't go. Seems the pump was broken. New pump took a month to come from the US and now its working. Best of luck!
Ps. Luckily the cost of ~4K€ was handled within the warranty, so it didn't cost me a cent.
