Applies to Audi A4s: with garage door opener (HomeLink)
Programming a button: Stage 1 (at the operating unit)
Switch on the ignition.
Press and hold down the two outer buttons in the headliner Fig. 2 until the LED -A- goes out completely (after about 20 seconds). This procedure will delete the standard factory settings and does not need to be repeated when programming the other buttons.
Briefly press the particular button in the headliner that you would like to program.
Wait until the LED -A- begins to flash rapidly. The programming mode is then activated for 5 minutes.
Step in front of your Audi A4 with the original hand-held transmitter for the system you wish to assign to the button in the headliner.
Programming a button: Stage 2 (at the radiator grille)
Hold the hand-held transmitter in front of your car's radiator grille Fig. 1.
Now press and hold the button on the hand-held transmitter until the turn signals on your Audi A4 start to flash. This can take up to 30 seconds.
If the hazard lights flash three times, the button has been programmed successfully. If the hazard lights flash once only, the programming operation has failed or the five minute programming period has expired. Repeat the programming procedure starting with the 3rd step, or try holding the transmitter nearer or further away from the radiator grille.
If the garage door or other system still fails to be activated using the buttons in the headliner after programming is completed, it is possible that the system might be working with a rolling code instead of the normal fixed security code. If this is the case, a rolling code programming is required in addition to the steps described above Link.
Follow the instructions above to program the other two buttons in the headliner. Start with the 3rd step.
Erasing the button programming
Programmed buttons can only be erased all at once; it is not possible to erase them individually. Reprogram the buttons if necessary.
Switch on the ignition.
Press and hold down the two outer buttons in the headliner until the LED -A- goes out completely (after about 20 seconds).
Reprogramming the buttons
Switch on the ignition.
To reprogram an individual button, press and hold the desired button until the LED -A- begins to flash rapidly (after about 10 seconds). Then release the button immediately. The programming mode is then activated for 5 minutes.
Continue with the 5th step.
Note
- Not all infotainment systems are equipped to program the system using the buttons in the headliner. Should this be the case, program the buttons according to the instructions under version A Link.
- The required distance between the hand-held transmitter and the HomeLink module inside the radiator grille Fig. 1 depends on the system you are programming.
- With some types of systems, you may need to briefly release the button during programming and then press it again. When programming a new device, keep the button pressed for at least 15 seconds before trying again with the transmitter in a different position. Watch out for your Audi A4s's hazard light signals during that time.
