6C 2014–2017 If the steering wheel is found to be off centre during the road test even though locating pins - T10096/ T10486/1- were used, check wheel alignment. In this case the wheel alignment test results must be archived in the vehicle files.
Specified torques
| Component | Specified torque |
|---|---|
| 6R 2009–2014 Swivel joint to suspension link ♦ Use new nuts. | 100 Nm |
| 6C 2014–2017 Swivel joint to suspension link ♦ Use new nuts. | 40 Nm +45° |
| 6R 2009–2014 Steering box to subframe ♦ Use new bolts. | 50 Nm +90° |
| 6C 2014–2017 Steering box to subframe ♦ Use new bolts. | 50 Nm +180° |
| Coupling rod to anti-roll bar | 40 Nm |
The two manuals give different torques for the same swivel joint nuts (N10332002): 100 Nm in the Polo 6R manual, 40 Nm +45° in the Polo 6C manual. Other cars with the same swivel joints differ too: the Audi A1 8X manual gives 100 Nm, the Škoda Fabia II manual 40 Nm +45°.
Different steering racks: the 6R has electro-hydraulic power steering, the 6C electromechanical. The bolts are tightened to different angles.
