It's won't completely disable it but if it works it's a start. I have also found a Youtube vid on a VW e-UP that follows the same coding -I have started this thread to share with you a recent discovery of mine.
All of you probably know that all the Scalas and Kamiqs are equipped with Lane assist systems (even the entry level ones). Although this system is usually very helpful, it is a bit annoying that once it is turned off in maxidot menu - assistance systems, it turns back on upon cycling a key.
However this is the coding that prevents this from happening:
-> Control Unit A5 - Driver Assistance
-> select Long coding
-> change setting Perso_HC from Activated to Last_setting
(changes bit 2&3 of byte 14)
-> press the magical green button to save the changes
tip: in case you get the error when saving -> (31) function not available, change the mode to vw - diagnostic mode, and try again (even if you are already using this mode, just reselect it again)
Once activated, the car will remember the last state of Lane assist (on or off) upon cycling the key.
