Tiguan R adaptations of all kinds

Hello, I am the proud owner of a tiguan R!
and I try to remove the beep sound! Be careful, the engine is running! When you open the driver's door with the engine running as well as the beep when you turn on the ignition and also open the door

I try to deactivate the start and stop (I have already modified the limit voltage to 12.1 V but without effect on this model)

Also I try to leave the Akrapovic exhaust flaps open all the time to let this little monster purr, who is just waiting for that! (In the meantime, I unplug the plugs from the valve motors on open in Race mode, without any errors noted)

And finally, I would like to let the last driving mode use the next time you start up because it is basically sport and I would like to leave it on individual for better comfort, but once the ignition is off it automatically returns to sport mode
, it's super annoying

And if someone has found some nice adaptations to the R, he can let it be known here with pleasure ;-)
