@Haylands; had contact with Patrick from GAP. Unfortunately this mod is only possible for the 2017+ L405. So no option for me

Think I'm going to try the "Stan-modification" again (disconnecting the rear cubby battery or signal wire to capacitor). When I did this before I got once the "restricted performance" message. I'll be prepared  2013 L405 3.0 TdV6 Autobiography Barolo Black
2004 L322 3.0 Td6 Vogue Cairns Blue (gone)
2000 P38 2.5 DSE (gone)

NB: The YouTube Video above from Lucky8 refers to the new Defender L663, for the L405 it’s slightly different:

Ign ON with iiD tool connected, press centre console swith to turn off Auto Start Stop. (No need for engine to be running) Then in iiD Tool Menu>CCF>Full List>Search:

“Multican-566 MHLastUserMode : 565” and select it.

Change value to “Last user memory mode enabled”.

Upload changes.

On cycling the ignition next time the car is started, the button in the centre console will illuminate to indicate ASS is turned OFF, and will remember its last setting each time the ignition is cycled, allowing you to choose whichever way you want it in future.  “If it ain’t broke, don’t fix it” -where’s the fun in that?

@rangie, that method worked on my 2015 tdv6 and now on my 2020 sdv6..both had the capacitor signal wire disconnected and no errors... ... - .- -.

@Stan:

You could now reconnect and do the iiD tool mod with your new car, allowing you to turn it back on (and off) at the touch of a button, say if you get stuck in a huge motorway tail-back and don’t want to waste fuel. “If it ain’t broke, don’t fix it” -where’s the fun in that?
