I just picked up my new e-tron yesterday! Happy to be able to be part of this group.

Trying to program the homelink garage door opener, but it's not working. Pressed HomeLink button, followed the instructions on the display, hold opener near the mirror, press the garage door opener button and hold. The garage opens, but nothing changes on the MMI. When I let the button go, I get a message that an error has occurred, do you want to try again.

Did some research and found some posts about the Side Assist interfering with the programming on some units. Sounds like if that is disabled by pulling the fuse, then programming, it might work. Has anyone had this issue, and how did you solve it?

Hi there and welcome to the forum!

I seem to recall getting an error when initially using the original hand-held transmitter to program. I believe the next step is to use the program button on the garage door opener itself, which is needed for most modern garage doors due to rolling codes. The older systems normally instruct you to skip directly to that step, but this new version makes you go in a certain order. Try remote first, fail, then do it the right way.

Page 42 in the Owner's Manual may provide some further insight if you haven't already checked that out.

Thanks for the response.

Even though lights on my garage door opener clicker would light up, and the garage door opened, I replaced the batteries and tried to program the e-tron homelink again... and this time it worked! Wasn't expecting that to fix it, but I'm glad it's resolved.

I also ran into this very same issue. I tried everything: replaced battery of the remote, held the remote near various places in the car, and yes I even tried disabling Side Assist by locating and removing the fuse! Nothing worked. It was infuriating! My next step was to take the car to the dealership and have them investigate.

But before that happened my father-in-law suggested that I try with a different remote. Amazingly, it worked!

My previous attempts were with a newer “universal” remote that I had purchased as a second remote for my previous car (which did not have HomeLink). The newer remote is small and uses a CR2032 button battery.

The original remote for the garage door opener is older, much bigger and uses a 9V battery. It’s one of these guys. When I tried programming with the original remote, it worked on the first try! I guess that the older remotes transmit at much higher power, and that’s what the e-tron requires. Who knew?
