Prerequisites:
•
•
Position vehicle on a firm and level surface.
Apply parking brake – the vehicle must not be moved while the
calibration procedure is being performed.
•
Align front wheels to straight-ahead position – steering wheel
in zero position.
•
•
Nobody may be inside vehicle during measurement.
Opening and closing the vehicle doors during calibration must
be avoided.
Special tools and workshop equipment required
♦ Calibration unit - VAS 6350-
♦ Vehicle diagnostic tester
Procedure
– Connect vehicle diagnostic tester .
– Switch on ignition.
– Attach 3 wheel bolt adapters (spanner size 17) to each wheel
centre mounting - VAS 6350/1- for the wheel securing bolts.
– Insert measuring paddles in both wheel centre mountings -
VAS 6350/1- , and secure them with clamping nut.
– Fit wheel centre mountings - VAS 6350/1- onto wheel bolts on
both rear wheels.
•
The turning centre of the wheel centre mounting must be in
the turning centre of the wheel.
Note
Fit wheel centre mountings - VAS 6350/1- onto the wheels so that
the “anti-theft wheel bolts” are not connected to the wheel centre
mountings.
– Adjust measuring paddles with the help of the clamping nuts
in such a way that they can move freely just above the floor.
•
•
The measuring paddles must not be restricted in movement.
The measuring paddles must be vertical.

– Position calibration unit - VAS 6350- at distance -a- to rear
wheels.
•
Dimension -a- = 1700 ± 10 mm.
– Push ON button to switch on spacing laser -VAS 6350/2- .
Display on -VAS 6350/2- :
•
“- - - m”
Note
The laser is switched on at the same time.
– Hold spacing laser -VAS 6350/2- -2- for distance measure‐
ment flush with stop bracket as shown in illustration.
•
When doing this, make sure that spacing laser -VAS 6350/2-
is firmly in contact with stop bracket.
– Ensure that the “laser beam” for distance measurement is at
the bottom enlarged part on the measuring paddle -1-.
If this is not the case, adjust height of measuring paddles using
lock nuts on wheel centre mountings - VAS 6350/1- .
– Now, briefly press ON button to measure distance.
Display on -VAS 6350/2- :
•
“1,700 m” (specification: 1700 ± 10 mm).
– Repeat the measuring process from the left stop bracket to the
measuring paddle on the rear left wheel.
•
Measured distance value must be identical on both sides.
If both measured values are not identical, adjust calibration unit -
VAS 6350- accordingly.

Note
The vehicle shown in the illustration may differ from the actual
vehicle.
– Attach calibration unit for lane change assist -VAS 6350/4- on
rear left on mounting of calibration unit - VAS 6350- .
•
If assembled correctly, the mains power lead should be fitted
to the bottom left of the calibration unit (as seen facing direc‐
tion of normal travel).
•
Dimension -a- = 744 mm (measured from upper edge of cali‐
bration unit to workshop floor).
– The dimension is set with the measuring point -arrow- at the
base of the calibration unit on the scale of the steel rule -1-.
•
Setting dimension left = 769 mm (read off on measuring scale
-1-).
– Connect the calibration unit for lane change assist -VAS
6350/4- to mains voltage.
– Bring the calibration unit - VAS 6350- to the horizontal position
with the aid of the vial (sight glass) -arrow- by turning the plas‐
tic feet.
– Put on “laser protection glasses”.
Note
The vehicle shown in the illustration may differ from the actual
vehicle.
– Switch on linear laser - VAS 6350/3- on calibration unit - VAS
6350- .
– Align the whole calibration unit - VAS 6350- so that the laser
beam is focused on the rear of the vehicle in the centre above
the Volkswagen emblem.
– Check the spacing on the left and right again between the stop
brackets of the calibration unit - VAS 6350- and the measuring
paddles -1- on the wheel mountings.

Calibrating lane change assist control
unit -J769- / -J770-
Note
Before the actual calibration process of the control units, the cal‐
ibration unit - VAS 6350- needs to be set up as described in the
following chapter.
Special tools and workshop equipment required
♦ Calibration unit - VAS 6350-
♦ Vehicle diagnostic tester
During the calibration process the following should not occur:
•
•
•
Vehicle doors should not be opened or closed.
There should be no-one in the vehicle.
No-one should pass through the space between the vehicle
and the calibration unit for lane change assist -VAS 6350/4- .
Procedure:
– Switch on the calibration unit for lane change assist -VAS
6350/4- using the mains switch -3-.
•
The green LED -1- must light up.
Note
If the red LED -2- lights up: Check the calibration unit for lane
change assist -VAS 6350/4- .
– Connect vehicle diagnostic tester .
– Select option for calibration in “Guided Fault Finding” mode
⇒ Vehicle diagnostic tester.
– Proceed by following the instructions on the display of vehicle
diagnostic tester .

– Switch off the calibration unit for lane change assist -VAS
6350/4- , and change to the other side.
As the program runs, you will be requested to change the cali‐
bration unit for lane change assist -VAS 6350/4- from the left to
the right-hand side of the calibration unit - VAS 6350- .
•
If assembled correctly, the mains power lead should be fitted
to the bottom left of the calibration unit (as seen facing direc‐
tion of normal travel).
•
•
Dimension -a- = 744 mm (measured from upper edge of cali‐
bration unit to floor).
Setting dimension right = 769 mm (read off from measuring
