My audi was in garage for 3 weeks, because they changed the steering rack and since when i went to pick it up there was 3 lights on the dash. ABS light, traction control light and warning for headlight range control. I decided to read the fault codes and i got these (text file). So i'm wondering that could they have messed something up during the steering rack project, is there any modules that control some of the electronics that could be faulty? Or could it just be the ABS right rear sensor that is faulty. I don't get any warning lights to the dash from airbag fault that is seen in the fault code log so i dont believe there is anything broken in airbag system and the steering angle sensor is the same thing. Warning lights on the dash (ABS, Traction control and headlight range control) show up only sometimes. I can drive 10km (6.2 miles) without those warning lights, but then they just show up out of nowhere.

Thank you for your help!
