The following are steps to programming a rolling code door opener to the Homelink transmitter in the Touareg.

The instructions in the owner's manual are correct, but after following them, my garage door installer and I discovered a few quirks and fixes for them.

It is important to park the Touareg in front of the garage door. Be careful not to park underneath it.

If your remote garage door transmitters are already programmed to your door opener, you need to do the following steps:

1. On the garage door opener itself, there is a learn button. Press and hold down the learn button until the learn indicator light goes out (approx. 6 seconds). (The learn button is near the antenna on your door opener.) By doing this, you have just reset the codes. At this point your remote door transmitters will most likely not work. This is o.k.

2. In the Touareg, press and hold whichever homelink button you want to program until the light above the homelink buttons slowly blinks. Continue to hold the button in and at the same time, hold your remote transmitter underneath the map lights and press the button. Continue to press both buttons until the homelink light rapidly flashes. Let go of both buttons.

3. You now have 30 seconds to press the learn button on your garage door opener. Press it once. The light will start to blink.

4. Go back to the Touareg, press and hold the homelink button you just programmed for 3 seconds until you get a blinking light. Repeat again. This time, it should open or close the door. The homelink button is now programmed.

5. Now that the homelink button is programmed, you now have to re-program your remote transmitters. Take the transmitters with you.

6. On the garage door opener, press the learn button, the light will blink. Now press the button on the remote transmitter. The light should stop blinking. Repeat the step if you have more than one transmitter. You should be all set. The homelink button should work in the Touareg and your remote transmitter(s) should also work.

In summary, the rolling codes in the door opener receiver have to be reset. For some reason, the Touareg has to be programmed FIRST. Then the remote transmitter units. If the remote transmitter units are already programmed, you will most likely not be able to program the homelink in the Touareg for a rolling code door opener.

Press and hold the two outer buttons on the homelink system in the car until the led flashes rapidly or goes out. Then hold the programmed remote up to the homelink system and at the same time press the button on the remote and the button on the homelink until the led light blinks rapidly or goes out. It should take less than 30 seconds. ----- Then go to the motor head and press the colored learn button on the motor head and go back to the home link and press the homelink button 3 times to activate. If your opener has dip switches stop at -----. Thanks BB

If you just received your vehicle and have not trained any of the buttons in HomeLink before, you should erase any previously learned codes before training the first button. To do this, press and hold the two
outside buttons on the HomeLink Transceiver for about 20 seconds, or
until the red indicator flashes.
Release the buttons, then go to step 1.
If you are training the second or third buttons, go directly to step 1.

1. Unplug the garage door opener motor from the electrical outlet.
2. Hold the end of the garage door opener remote 2 to 5 inches from HomeLink. Make sure you are not blocking your view of the red indicator in HomeLink.
3. Press and hold the remote transmitter button and one of the HomeLink buttons at the same time.
If the red indicator in HomeLink begins to flash slowly at first, then rapidly, release both buttons, and go to step 5. If the red indictor in HomeLink continues to flash slowly (does not flash rapidly), your remote transmitter may stop transmitting after a short time. Go to step 4.
4. Press and hold the remote transmitter button and one of the HomeLink buttons at the same
time. While continuing to hold the HomeLink button, press and release the remote transmitter button every 2 seconds. If the red indicator in HomeLink begins to flash slowly at first, then rapidly, release both buttons, and go to step 5. If the red indicator in HomeLink continues to flash slowly (does not begin to flash rapidly), repeat steps 2 thru 4.
5. Plug in the garage door opener motor, then test the HomeLink button by pushing it for about 1
second. If the button works, programming is complete. If the button does not work go to step 6.
6. Push and hold the HomeLink button for a few seconds, then watch the red indicator on HomeLink.
If the indicator stays on or flashes slowly, repeat steps 2 thru 5. If the indicator flashes rapidly
for 2 seconds then stays on, you have a rolling code transmitter. Go “Training with a Rolling Code System”
7. two HomeLink buttons to operate any other compatible remotely controlled devices around your
home (lighting, automatic gate, security system, etc.).
Repeat these steps to train the other

Try this.

HOMELINK PROGRAMMING

1. Clear out anything previously programmed into the in-car system from the factory by holding down on the 2-outside buttons simultaneously, until the in-car LED starts flashing rapidly. This may take up to a minute (in most cases, the key should be on auxilary, and/or the car door must be shut).
   
2. Decide which button you want to make to be your in-car garage door transmitter. Hold your transmitter up near the selected button, pressing both the garage door remote and the selected in-car transmitter button simultaneously. Hold down on the buttons until the in-car, LED light flashes rapidly. This sets the in-car remote transmitter to be your garage door openers make transmitter, but you are not done. You now need to make this in-car transmitter your personal transmitter.
   

3. Go to the Learn Button on your garage door opener. The button is usually next to the area where the floppy antenna is connected to the motor head. With Genie it is most often behind the light lens, and an indicator light flashes red when pressed. With Sears or Liftmaster (Chamberlain) it is near, or part of, the terminal screw board, and is a red, green or purple square button with a green, amber or purple indicator light. Press this learn button momentarily. The indicator light will turn on and blink if Genie or otherwise stay lit. For Genie systems, go back to the in-car transmitter button you programmed and press this button 3 or 4 times, or until the door starts moving. This should set your in-car transmitter to your garage door opener. For Liftmaster, Sears, or Linear Megacode press and hold the in-car button you programmed until the garage opener light flashes. Your in-car is now programmed to operate your door.

THEY MAKE THE SYSTEM AND HAVE INSTRUCTIONS YOU CAN DOWNLOAD.

PLEASE NOTE: NOT ALL BRANDS/MODELS OF OPENER WILL WORK WITH THIS SYSTEM.

HOPE THIS HELPS

Sorry, the process is simple but too lengthy to post here.

Goto homelink.com

They make the system and have very complete instructions you can download.

PLEASE NOTE: MOST but not ALL Brands / models of opener will work with this system.

Try holding the hand held remote up next to the homelink (built in remote). Hold down the botton on the hand held remote and the botton you want to program in the car at the same time until the homelink light goes out. This could take 60 seconds or more. Now depending on which model garage door open and how old it is you may need to program the car to the opener. Usually this is done by pushing the botton on the back(Liftmaster,Sears, Chamberlin) or the botton on the front(Genie) and then go to the car and push the same botton on more time. I hope this helps.

1. Position vehicle within 10 feet of garage door- engine off and battery on.

2. Press/hold 2 outside buttons of Homelink transceiver until red indicator starts flashing rapidly, then release button. This should take about 20 seconds. This erases any previously learned codes.

3. Press/hold remote control and press/hold button of Homelink transceiver simultaneously. Slowly move remote control from 5" away to 1" away from Homelink transceiver. Release both buttons after red indicator starts blinking rapidly. This should take about 5 seconds. I discovered that the Homelink in my TL is a bit faulty because it took much longer to accomplish this than when programming the Homelink in my MDX. My TL's Homelink may "unlearn" it's code in the future and the needed proximity of the TL to the garage door may be much closer than desired until I get the Homelink fixed.

4. Press training button on garage door opener unit until the indicator lights illuminates- this should be immediate.

5. Within 30 seconds press/hold the Homelink button for 2-3 seconds until the red indicator starts flashing rapidly. Repeat a second time. It should now be programmed. Check it by pressing the programmed button on the Homelink receiver.

6. When programming more than 1 garage door opener unit, disconnect power from unit before programming more units. By not doing this the programmed unit could conflict with the unprogrammed units commands.

Problems:

1. The Battery in the garage door remote may be too weak to program Homelink. However, the battery may be strong enough to operate the garage door. One of my remote controls had a weak battery- my system was installed today, fresh out of the box. I had to use the second remote control for the programming of Homelink on my 2 vehicles.

2. Antenna on the garage door opener unit must be hanging down, fully extended.
