Applies to Audi A4s: with garage door opener (HomeLink)
Some devices require rolling code programming.
Identifying a rolling code
Press a programmed button in the headliner again and hold it down.
Watch the LED -A- Fig. 1. If the LED starts flashing rapidly, this indicates that the system you wish to operate, such as a garage door, is equipped with a rolling code.
Program the rolling code as follows:
Activating a system's drive unit
Locate the programming button on the system's drive unit. The exact location and colour of the button may vary depending on the type of system.
Press the programming button on the system's drive unit (this will normally cause an indicator lamp on the unit to light up). You now have about 30 seconds to start and complete the programming process for the button in the headliner.
Programming the button in the headliner
Press the previously programmed button in the headliner for 2 seconds.
Press the button for 2 seconds again to complete rolling code programming.
For some systems, the button may have to be pressed a third time to complete the programming sequence.
After programming, the system should recognise the signal and respond when the button in the headliner is pressed. Now the other control buttons can be programmed as required.
Note
- Having a second person assist you makes programming of the rolling code easier and faster.
- If you encounter problems programming the rolling code you may find helpful information in the operating instructions of the system you wish to operate.
