I've been a member for a long, long time but I don't post very often, only when I have a question. So, I'm unable to get my Home link mirror to accept any codes from either of my 2 Garage Door openers. I clear the memory by holding the 2 outer buttons, a solid yellow light comes on but it doesn't turn a solid green, it only shows a very rapid Green flash. I'm stuck at this point, it should be showing a solid green light so I can continue. The dealer keeps sending me home to try it with the actual door, it's a 2020 S63 Sedan and my 4th W222, I thought I knew what I was doing, obviously I don't, any help would be great, Thanks !!

 

Sounds like you need to push the "learn" button on the actual garage door unit (mine is red) during the linking process.

This link pointed in the right direction.

 

So there might be another issue that I ran into with my gate openers. My gate openers use a different frequency that is not Homelink compatible. What I did was buy an aux receiver that IS compatible with Homelink.

Once you get the reciever it is wired to the garage door openers just like a wall switch is wired and you program the remote that came with the receiver to your car.
