Adaptive Cruise Control (ACC), Cali‐

brating

Special tools and workshop equipment required
♦ Setting Device Basic Set - VAS6430/1-
♦ ACC Reflector Mirror - Audi - VAS6430/3-
♦ Wheel Alignment Computer
♦ Vehicle Diagnostic Tester

Note

♦

Before adjusting the ACC, check the sensor, its mounts, and

securing elements for damage, external influences and secure

fit. Repair any damaged components, if necessary.

♦

Prior to adjusting the adaptive cruise control (ACC), check the

event memory and correct any malfunctions.

♦

The ACC control module “adjustment angle measured value”

shows whether the sensor is misaligned.

♦

The ACC adjustment may only be set using a VW/Audi-ap‐

proved wheel alignment device and adjustment equipment!

♦

Proper ACC operation requires correct alignment.

Note

♦

A new adjustment is necessary if:

♦

The rear axle toe was adjusted.

♦

The Distance Regulation Control Module - J428- was removed

and installed.

♦

The front bumper carrier was removed and installed.

♦

The front bumper carrier was loosened or moved.

♦

The adjustment angle is greater than -0.8° to +0.8°.

♦

The vehicle was moved to the service position.

Note

♦

Before driving the vehicle onto the alignment stand, make sure

there is enough space between the vehicle and the Setting

Device Basic Set - VAS6430/1- . The distance between the

ACC Reflector Mirror - Audi - VAS6430/3- and the sensor must

be 120 cm ± 2.5 cm (47.2 ± 0.98 inches).

♦

If there is not sufficient space, drive the vehicle backward onto

the alignment stand in order to use the corresponding space.

♦

If the ACC Reflector Mirror - Audi - VAS6430/3- is repositioned

on the calibration beam during the adjustment, the Setting

Device Basic Set - VAS6430/1- setting must always be

checked (for example bubble levels, individual toe settings at

the calibration beam, etc.).

• Before beginning the adjustment, check the Diagnostic Trou‐

ble Code (DTC) memory and correct any malfunctions

present.

The adjustment procedure is described here using the Setting

Device Basic Set - VAS6430/1- .
Follow the sequence for adjusting:
1 - Establish a distance of 120 cm ± 2.5 cm between the cen‐

trally positioned ACC Reflector Mirror - Audi - VAS6430/3-

and the sensor in the air grille,

2 - Attach the ACC Reflector Mirror - Audi - VAS6430/3- in the

center of the calibration beam,

3 - Adjust the Distance Regulation Control Module - J428-
Do not perform the steps under “Calibration procedure without a

previous axle alignment” if an axle alignment has already been

performed.
Calibration Procedure without Previous Axle Alignment
– Select the ACC calibration button on the alignment computer.
– Follow the test requirements for an axle alignment. Refer to

⇒ “3.2 Test Prerequisites”, page 296

 .

– Drive the vehicle onto the vehicle alignment platform.
– Connect the battery charger. Refer to ⇒  Electrical Equipment

General Information; Rep. Gr.  27 ; Battery, Charging .

– Connect Vehicle Diagnostic Tester (Guide the diagnostic ca‐

ble through the open window.)

Note

During the adjustment procedure, make sure all the vehicle doors

remain closed and the vehicle exterior lamps are switched off.

– Position the front wheels so they are straight.
– Install the quick-action clamps on the rear wheels.
– Install the measurement sensor on the rear wheels.
– Perform a wheel run-out compensation and the rear wheels.

Calibration Procedure with or without Previous Axle Alignment
– Remove the trim -1-.
– Remove the trim -1-.
– Remove any dirt that may be on the sensor lens.

– Position the Setting Device Basic Set - VAS6430/1- at a dis‐

tance -a- from the centrally positioned ACC Reflector Mirror -

Audi - VAS6430/3- in the center and parallel with respect to

the Distance Regulation Control Module - J428- .

a - 120 cm ± 2.5 cm (47.2 ± 0.98 inches)

Note

The Setting Device Basic Set - VAS6430/1- must not be moved

on the calibration beam.

– Position the front wheel measuring sensors -1- on the calibra‐

tion beam.

– In area -A-, bring item -2- on the rotary knob into alignment

with the marking on the mirror (number 2 on the rotary knob

must face the vehicle).

– Level the bubble levels -A and B- on the ACC Reflector Mirror

- Audi - VAS6430/3- using the adjusting screws -1, 2, and 3-.

– Adjust the mirror -4- via the crank -arrow- so that the laser

beam is in the center of the sensor lens.

– Position the mirror on the side of the calibration beam so that

the laser beam is in the center of the sensor lens.

– Level the bubble levels -2- of the measurement sensor -1-.
