*** Updated March 12 ***
Here is the procedure for performing the Over The Air update for these doors.
Hansshow has been very responsive to this issue and has mostly resolved it. They have addressed the biggest problem which was that we were unable to update the Auto-Presenting door modules Over The Air (OTA). This is a huge relief to me and, I’m sure, many others who have installed these great door modifications.
The only outstanding bugs are relatively minor: The passenger door now responds and opens on demand but will only open about 12 inches. I have relayed this back to Hansshow and am pretty confident they will be able to resolve the issue quickly.
The other issue is a bit more obscure. I use S3XY Buttons to open and close the passenger door, mostly as a convenience for my wife as she approaches the car with hands full of stuff. This has always worked fine. But now, with Tesla’s update and Hansshow’s response in firmware, when I close the door using these buttons I get a message:
“Front right door failed to open in Mobile App”
It’s a bit obscure, but it appears that Hansshow doesn’t return an expected response to Tesla when you close the door with other than the Tesla Door Open button or Hansshow’s little black Control button that comes with the unit. Tesla doesn’t expect Model Y cars to have any door automation so basically you issue an “Unlatch” command to both open and close the car doors. When this command is issued by the S3XY button it seems that, even though the door has closed itself and the soft-close module has pulled it shut, some message has NOT been sent back to the car’s computer to indicate success. I have notified Hansshow to see what they can do.
I recognize that this is going to be a niche case as, because of the cost, I am sure that not a lot of people have invested in the Passenger door Auto-Present hardware and, of those, I’m sure it’s only a subset that ALSO use the S3XY buttons. I’m not sure if there are any other apps out there issuing UNLATCH PASSENGER DOOR commands..

I did receive a response from Hansshow which was the first time I’ve been a bit disappointed with them. It was nonsense, which could be a translation thing, but I interpretted it to be double talk for “We don’t want to support Over the Air updates so you need to take apart both your doors in order to apply the update manually via an SD card”. Below is what I received and what I sent back in response. I remain hopeful that they won’t just leave us out to dry.
*** End March 8 Update ***
It is not wholly unexpected that updates to Tesla’s firmware might cause issues with 3rd Party after-market items. Especially those that are trying to integrate in with the car’s other functions.
On the heels of my Tesla Model Y Long Range having a passenger door issue after Tesla’s 2024.45.25.15 update. I now have this current issue as of Tesla’s 2024.45.32.10 and 3 subsequent updates (2024.45.32.15, 2024.45.32.20 & 2025.2.8).
The issue is that, first thing in the morning, or after the car sits for a few hours, both my driver and passenger doors work just fine. They open and close as they should. But the moment I touch the brake, they no longer open, they merely unlatch. *Most* of the time the driver’s door will finish closing if I begin pushing it shut, and usually pressing the Hansshow-provided black control button will close the door properly.
It was pointed out in one of the Tesla Motors Club forums that the ODBC port that the door modules are hooking into is not intended to be publically accessible and, hence, any API being used by Hansshow in order integrate with the car’s functions is subject to change. So Tesla can (and should be able to) change these interfaces as they see fit and it’s up to the third party (Hansshow in this case) to play catch-up and develop firmware updates for their Auto-Presenting door modules to reintegrate the door functionality so it works normally again.
Almost certainly you will need to use the door module’s built-in Over the Air (OTA) upgrade feature. I’ve described how to initiate this, along with other changes to the door parameters, in this Post about the Hansshow Auto Presenting door control button.
For their part, Hansshow has been reasonably responsive to my messages asking about a fix. Initially they were still waiting for their own test vehicle to receive the problem update so they could reverse-engineer the new messages being presented through the ODBC interface and respond accordingly.
I am publishing this in case others are stuck and wondering what to do about their investment in Hansshow’s Auto-Presenting doors. The answer, for the moment is still: be patient. I’m going to follow up early next week to see if they have an ETA for a fix.
