15 | Detach steering angle and steering-wheel torque sensor (A77) using a suitable tool from the electromechanical controller unit (5) and carefully place to one side | | |
| Check | ||
16 | Use an endoscope or a commercially available inspection mirror (11) to check whether the gear (12) of the steering angle and steering-wheel torque sensor (A77) is properly welded together | The gear (12) is properly weld where welding pins (arrows B) are not present, but rather a weld seam (arrow A). | |
If the gear (12) has been properly welded together or if the weld seam (arrow A) is visible. | |||
| |||
Continue with operation step 17. | |||
If welding pins (arrows B) are visible. | |||
| |||
Mount steering angle and steering-wheel torque sensor (A77) and replace steering gear. | |||
