What seems to be lost on a lot of people is that there are several methods all have different results depending on the car you drive.
Example:- My golf 7.5 "R" coding method results in a perm error message icon on the electronic display. Unplugging the Battery voltage sensor just gives one flash message that goes away after about few seconds. If you blink you will miss it. I also have a gadget (my current solution for the golf) that plugs into the back of the start stop disable switch. Every time you start the car is electronically presses the start stop switch.
Polo AW GTI:- I did not try the coding method because I assumed I would get the same perm error as the golf, Thus preferred the flash message, so unplugged the sensor. I also have a gadget (mentioned above) for the polo but have not installed because I cant work out how to remove the center console to get to the switch.
Thus given everything above I just think that pulling the plug is the simplest solution. Other probably disagree.
