Volkswagen Golf Service & Repair Manual: 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. |

Note
Before working with a finish balancer, the mechanic needs to
have been instructed by the manufacturer of the balancer.
...
Radial and lateral run-out occur when the wheel and tyre do
not run absolutely true.
For technical reasons, 100% true running is not possible.

Other materials:
Seam seals, rear body
Note
Seam seals made during repair work must be identical in
appearance and thickness to the original seam seals.
To avoid damage or faulty operation, brush seam seals smooth
near attachments which must be attached.

Safety precautions when working in the vicinity of high-voltage components
Danger to life due to high voltage
The high-voltage system is under high voltage. If high-voltage
components are damaged, there is a risk of severe or fatal injury due to
electric shock.
–
Perform visual check of high-voltage components and high-v ...
