Checking the Tightening Torque
The correct wheel bolts must be used for all vehicle types; these bolts must always be tightened with the correct tightening torque. The tightening torque of the wheel bolts must be checked regularly with a properly functioning torque wrench. In addition, the tightening torque must be checked immediately after every wheel change with a properly functioning torque wrench. If the tightening torque of the wheel bolts is too low, the wheel bolts and rims can loosen while the vehicle is in motion. The wheel bolts and the threads could be damaged if the tightening torque is too high.
If the wheel bolts are corroded and stiff, they must be renewed and the wheel hub threads cleaned before the tightening torque is checked. Never grease or oil the wheel bolts or the threads of the wheel hubs.
Tightening torque for wheel bolts
The tightening torque for wheel bolts is specified in the chapter Changing a wheel.
WARNING
Incorrectly tightened or missing wheel bolts can lead to loss of control over the vehicle, serious accidents and fatal injuries.
Never drive if wheel bolts are missing or loose. Always use wheel bolts that match the wheel rims and the vehicle type. Tighten the wheel bolts with the correct tightening torque every time. If a torque spanner is not available, tighten the wheel bolts with a wheel spanner and then immediately check the tightening torque at the nearest appropriately qualified authorised workshop. Volkswagen recommends an ID. UNYX Service Center. Never grease or oil the wheel bolt and the threads in the wheel hubs. This could cause the wheel bolts to loosen while the vehicle is in motion, even if the required torque setting is used.
