BMW F10 Integral steering problems
 

Hello guys. Car is bmw 530d 2011. Never had this error message before. It started to appear only after driving in snowy cold weather for 2 days. Since then each time after starting the car it appears when i try to move steering wheel to any side, or after driving for like 5 minutes. Any ideas what can cause the error? First two days there were no sounds or driving difference, but today while driving, my steering wheel went out of center like 30 degrees and now to drive straight steering wheel is in this position like in photo above... https://static.xx.fbcdn.net/images/e...1/16/1f641.png
