That sounds interesting.... I thought the lane assist setting was in the SFD protected bit - or at least on the Golf. What did you set?
The only thing I've done is turn on the exit warning system, which is disabled on my GTI for some reason - the later ones its not.
Much of what you will want to tweak however will be in the SFD protected controllers...
Just pulled from my post on the EV forum:-
How to have lane assist remember what it was last set to e.g. leave it off unless you want it on:-
Control Unit>A5 Assistance systems>configuration for lane departure warning>change "active" to "last setting" then ok>press and hold green tick to save it.
The mirror settings is on a toggle switch that cycles a light to each setting, but annoyingly, the car always forgets you left it on "L" last ignition cycle, so you have to remember to put it to L every journey if you want mirror dip on reverse ' is the MK8 like that or is there a physical switch like MK7 and everything before where you can see it physically set to L?
Anyway, it's annoying it forgets L for mirror dip. There are 3 settings in drivers door controller that look as though they would either make mirror dip on reverse or make the car remember last mirror settings:-
1 = memory mirror
2 = mirror lowering with rear gear
3 = position memory with rear gear
Neither one on its own or a combination of 2 or 3 of them seem to work.
There was a rumour that the difference between those with 2 zone climate and those with 1 zone is purely software on the ID3. Our Life has 1 zone and our Family spec has 2 zone. Set Life up as Family in aircon controller and still operating as 1 zone.
Activating travel assist asks for a 5 digit code.
My biggest annoyance - lane assist coming back every ignition cycle, is resolved, so that's a win for me.
