The garage door will open with the remote but will not shut with the remote and the light blinks you can shut the door by holding the button on the wall until it completely closes. This is a 3 door garage and the two outside doors work with the remote so I think the sensors would be ok

If you have a 315MHZ LiftMaster Garage door opener do the following:
Follow the purple wire (Antenna) up and you will see a square purple button.
Press and hold the square purple button for ten seconds until the amber led goes out.
Press and release the purple button one time (The amber led will come on solid).
Press and hold the button on the garage door opener remote control for two seconds (The light bulb on the garage door opener will blink and you will hear a click sound the amber led will go off).
to program the wireless keypad do the following:
Press and release the purple button one time (The amber led will come on solid).
Enter a four digit code into the keypad then press and hold the enter button for two seconds (The light bulb on the garage door opener will blink and you will hear a click sound the amber led will go off).

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.
