Audi Q7: Headlamps, Calibrating
Note
Only Matrix LED headlamps must be calibrated.
Matrix LED Headlamp, Calibrating using Headlamp Adjusting Unit -VAS5209B-
Special tools and workshop equipment required
- Headlamp Adjusting Unit -VAS5209B-
Note
- The Matrix LED headlamp is calibrated. Refer to Vehicle Diagnostic Tester.
- In this procedure the low beam is set first. Then the Matrix beam high beam function is calibrated.
Note
Software version from V 0.80 for the -VAS5209B- is required to calibrate the Matrix beam high beam function.
The Matrix Headlamp Must Be Calibrated after the following Work:
- Headlamp position was changed (removing and installing, loosening and tightening the screws)
- Headlamps were adjusted.
- The Driver Assistance Systems Front Camera -R242- was replaced.
- The Drivetrain Control Module -J775- was calibrated or replaced.
- The Vehicle Electrical System Control Module -J519- was replaced.
- The Left Rear Level Control System Sensor -G76-, Right Rear Level Control System Sensor -G77-, Left Front Level Control System Sensor -G78- or Right Front Level Control System Sensor -G289- was replaced.
- The windshield was removed and installed ore replaced.
- "No or incorrect basic setting/adaptation" is stored in the DTC memory.
Requirements
- Follow the complete test and adjustment requirements. Refer to → Chapter "Headlamp, Adjusting".
Procedure
- Align the Headlamp Adjusting Unit -VAS5209B- at the distance -a- = 100 mm to the vehicle center. Refer to the Owner's Manual.
- Check the parallel alignment of the Headlamp Adjusting Unit -VAS5209B- to the vehicle transverse axis. To do so, align the laser beam of the Headlamp Adjusting Unit -VAS5209B- to the left and right front fender bolts -arrows-.
- Push the -VAS5209B- in front of the left headlamp and check the parallel alignment again.
- To prevent glare for the other motorists, pay attention to the exact orientation of the headlamp adjusting unit.
Calibrating
Vehicle Diagnostic Tester is connected.
- Select the Diagnostic mode and start.
- Select the Test plan tab.
- Press the Select individual tests button and select the following one after the other:
