When you press the button on the fob or the one under the dash is the lower tailgate supposed to open with the upper?

Mine doesn't but I've seen some that do, how is it enabled?


The lower part operates fine electrically and it closes in sync with the upper using the remote or any other button. Current

on mine and when locked ,you press the tailgate button on the fob and both power and upper open...you have to use the fob to close unless you 'unlock' whilst the back is open.

if you use the the button in the cabin only the tailgate opens.
if you press the button on the tailgate , again only the tailgate opens.. ... - .- -.

.....and, it seems like whether locked or unlocked the only way to open both upper and lower tailgate is to use the fob... ... - .- -.

The more I read the more I think it should be opening. I'm not convinced anything is faulty. It seams more likely that something isn't enabled.

When I get chance and the weather is decent I'll have a play with the IIDTool and see if I can find anything. Current

Mine : button on tailgate or switch on dash - top only opens
Gesture or remote - both open 2021 L405 Vogue SE 4.4 V8 DIESEL ~ #17

I have wondered about this also! My FOB only open the top tailgate, i have to use the button on the lower tailgate itself to open that yet BOTH will close with one touch of the button on the keyfob

MY19 - both open only with the fob or by wiggling the foot under the bumper. If the dash switch or the tailgate button are pressed - only the upper part.

Its an age related upgrade... 13/14/14.5MY's do NOT allow top & lower tailgate opening im afraid... Yet another thing the 15MY cars improved on...

Hmmmmm I wonder if there is a firmware upgrade available, can only be software related not hardware surely ! Bit like in the old days of video games where you could download a 'trial' version of the game, the WHOLE game was actually on there but the software would only allow you to play for so long..... trial version..... unless you knew where to look and how to unlock it all  CURRENT :

The issue is canbus protocol! 2013-2014.5 have very different canbus to 2015-2017 for example! So, it’s only possible if the boot opening can messages are interpretable?

Hopefully that makes sense? 👍

Interesting!!! I like silly little issues like this, will have to look into it as at the end of the day the fob sends a signal to the car to open the boot, canbus thinks,,,,, I know ! I am a mere 2013 model, I will send a signal to open just the upper boot, that will do ! I see no reason why the system can not be told to send the open boot signal to both the upper and lower tailgate to they BOTH open ?!? (may need to tap into the lower tailgate button with a few wires and a bit of solder to a relay picking up a live feed trigger from the upper boot module..... but could work !

Anyone know if there are any detailed manuals on the canbus systems, any one know if you can DUMP to usb the files or protocols from the car? What language is it programmed in?

This could turn into a right project if I can get my hands on the coding involved then maybe be able to make a few interesting or unusual mods (You can tell I am bored to death in lockdown can't you!) Maybe some electric rear boot struts could be rigged to open the bonnet (not from fob, internal button maybe?)

If anybody knows anybody who may have info on the canbus system, specifically files, programming language etc could be interesting although...... I have a feeling somebody is going to come and burst my momentary bubble ..... thats what ususally happens when i 'THINK' I have an idea !!!  CURRENT :
