I want to say that I’m pretty sure there’s a setting to turn the lane assist and emergency braking (AEB) off, without having to disable at each start-up. I went through the set-up process when I first took delivery, and IIRC I turned them off because none of those “aids” have ever engaged. I do the same thing as you for right-hand turners. The lane assist is definitely off because there are many time I’ve crossed the double yellow or white shoulder lines to go by people waiting to turn.
UPATE: So I guess you can’t turn it off permanently because I just tried 😃. Interesting how none of them have never engaged🤷🏻♂️

same on my 2022 P300, I turned it off in the settings and it stays off. same with the emergency braking assist, that has kicked in a few times when it shouldn't have and scared the crap out of me.

Definitely a head scratcher 🤷🏻♂️ but I’m glad they haven’t kicked-in yet🤞🏻

Wow, this thread is painful. Two and a half years and eighteen pages of posts and nobody has a solid solution to this annoying "feature" for the 2020 Defender?
Maybe I missed it up above, but it looks like there is a pretty easy fix with the GAP IID tool (video below). Now I just need to find a friend or shop in SoCal with the GAP tool to shut it off. I have no desire to disable my battery monitoring system, because sometime I go a long time without driving the vehicle and the low battery messages are important.

I may be mistaken but I think this only works on the P300 not the P400. I had the CCF config changed on my P300 and no longer have to be bothered turning it off.

Just to throw this out there, I own a 2020 P400 and I own a GapTool and I know my way around the car with it. However, mine will *not* disable the auto start/stop with the method used by Lucky8 above, even playing around with the start/stop button setting before writing the CCF as they do in the video above.. It's not operator error... the car won't take the coding. A few others have posted this as well.
(which, by the way I'm fine with because I don't actually want to disable it... I like the functionality of sitting in eerie silence at the stoplight...)

Me too. I have a 2020 P400X and no go no matter how I try to do it. I have finally gave up. I also tried the walk away locking and unlocking even though everyone says it only works with the 2023 onwards. Anyone know what is missing too make it work.
