Volkswagen Golf Service & Repair Manual: Vibration, vibration control system
| Using the vibration control system -VAS 6230 A- you can
perform more functions than just stationary balancing. |
| A special feature of this system is the testing of the
radial force of the wheel and tyre while rolling. |
| A roller presses against the wheel with a force of about 635
kg. This simulates the vertical tyre force against the road
surface during travel. |
| Radial and lateral run-out in the wheel and tyre and
differences in the stiffness of the tyre cause the vertical
force of the wheel to vary. |
| The -VAS 6230 A- detects and stores the position of the
maximum measured radial force in the tyre. Then the position of
the smallest distance between the wheel rim flange and the
centre of the rim is measured. |

If a customer brings a vehicle to the workshop complaining
about “vibration”, a road test is essential prior to balancing
the wheels.
