Steering noise with grinding sensation.

So I got my 535i back after two weeks in the shop to repair ars. Now there is a weird noise and sensation when turning to the right a low speed. Kind of like a farting noise with a grinding sensation in the steering wheel. A bit like when a wheel bearing is shot but it's only noticeable at low speeds and not always. I think I saw a post of someone having a similar problem. Anyone who have some insights? I guess the car is going back to the shop.
