How do I program my Audi A6 garage door opener?

I recently purchased an Audi A6 and I am having trouble programming the garage door opener. I have tried following the owner's manual, but it is not working. Can anyone provide clear and specific instructions?

To program your Audi A6 garage door opener, start by pressing and holding the two outer buttons on the vehicle's remote for about 20 seconds. Then, press and hold the button on your garage door remote until the indicator light starts flashing rapidly. Finally, press and hold the programmed button on your vehicle's remote until the indicator light turns solid. For more detailed instructions, you can also watch a tutorial on YouTube.

Make sure to have your garage door remote and vehicle remote within reach before starting the programming process. This will make it easier to complete the steps without any interruptions. If you are still having trouble, try contacting your local dealership for assistance. They may be able to walk you through the process or provide you with a different remote that is compatible with your specific garage door opener model.
