Homelink retrofit install failure

[terranx]

I have 2 Tesla model 3's. Installed homelink in both today and 1 car worked and the other didn't. I'm not sure why it worked for one and not the other. Both are on the newest update.

Are they both on the 2024 software ("newest update" doesn't mean much since Tesla rolls these out at seemingly random for car to car)

I successfully installed an "Ebay" module last month in my 2023 M3. I am still on the same software (2023.44.30.8) as when I installed it. Has anyone lost functionality of the Homelink module after a software update (i.e. 2024 build)?

Should be fine

can you share the link of the video?

I cannot find it now. I think you just have to reboot the MCU and clear the HomeLink memory for it to work. Software needs to be installed through the service menu. Hope this helps!

If you find the link to the video, please let us know. I can check to see if it would work.

I installed a module off of eBay in my Dec 2023 purchased MYLR in late January on whatever was the latest update as of late January. It definitely failed the first time. I either just ran it again or rebooted/shut down the car and ran it again and it worked.

Due to my rural location, I have almost zero LTE connectivity, if that helps understand the issue any better. Like when my car is parked I cannot usually access the car via the app.

Hmm that's a good idea also, was just curious what version was your firmware, I doubt it was 2024 though but it would definitely be interesting to see if it's not connected to a network would allow it to work, I doubt it though but no harm in trying.

From what I can recall I think it did have high fidelity park assist and maybe one update after that.

Same here. Installed last month when I was on 2023.x.x. Now on 2024.2.6. No issues. Homelink works just like it did before.

I have my new Model Y now, and honestly having just spent $50k on a car, the idea of struggling and fighting to get an eBay sourced homelink working in order to save $100 is just crazy, got better things to do.
I've just ordered the Tesla part direct and will happily let the Tesla tech install it for me and move on with my life.

Did you update the config (tell it you have homelink)

That's the issue. Apparently 2024+ software no longer allows that (tbd if deliberate or not, but I'm leaning towards deliberate).

This ^^. Its just not worth it to save $100 because its a hit and miss (mostly miss).

Until a couple weeks ago it was basically a 100% hit. It’s also nice to be able to avoid the Tesla service center since many of us don’t live close to one and don’t get serviced by mobile service either.

Here is a good YouTube video and this guy does a good job! I could have tried this if I had come across it earlier! It may still help some of the new MY owners.

I self-installed a module from eBay mid December on a December 2023 new MYLR. Has continued working with the new 2024 software releases so far. It was NOT about saving $100, it was about driving 3.5 hours each direction to the closest Tesla service center vs. spending about 30 minutes to install it myself. We had a great mobile ranger but he moved on to a better job with Tesla energy. Given how hard it is to hire people, we've had no new ranger for at least the last year. Since then, it's a bear to get any Tesla work done due to that 7 hour round trip commute.

Yeah! That is a huge problem with Tesla. I wonder if they make an exception and allow DIY installation if you talk to them nicely! Fortunately! Here in Greensboro we have a great mobile service and the nearest service center is only an hour away. I hear Tesla is building a new service center in High Point, NC which will reduce my travel distance to a service center to about 5 minutes from my work! Yay!

are you able to do this step ?

I dont know but there are several people including the guy in the YouTube video that claim the installation on late 2023 or early 2024 MY! Only way is to buy a cheap module on eBay and try it out. If it does not or yo can return it for a full refund and go buy one from Tesla!

Mine is 12/23 model Y, purchased it in mid Jan 24 with Jan software installed on the very same day of purchase.

Late Jan 24, I received my eBay package of homelink module. Followed the installation process as per YouTube and it went thru!! No issues.

Very few ppl are facing issues with the installation and I believe these people have got car with some configuration issues to begin with.
