I did the coding to remember previous setting as to if the button was on or off.

It worked for a few days but weirdly now its back to me having to press it evertime I start the car to turn it off.

I followed this coding;

Select]
[09-Cent. Elect.]
[Security Access - 16] (enter security code - 20113)
[Adaptation - 10]
Select Channel 34 and Read
if you subtract 4 from the original value --> Start&Stop always disabled
if you add 32 to the original value --> memorize last status (the Start & Stop status at engine startup will be the one at last engine shutdown)
if you add 64 to the original value --> Start & Stop button light will be reversed: off if Start & Stop is disabled, and on if Start & Stop is enabled.
Press Test then press Save

Has anyone else had this? Should I try and code it again?
