Replacement W211 Steering Contact Piece.
Have you ever had a problem with the signal not turning back after using it. This happened to this W211 model and we found that the Steering Contact Piece was damaged because the inside of this part was broken. After switching it, the signal conversion is as usual, and the signal switch can return to its original position after use.
This part is also known as Airbag Spiral contact too because this component works for the airbag system located on the steering wheel.
