I haven't test driven a Kodiaq yet so some of these items may be activated already (although they are not on the Superb or Octavia which are built on the same MQB platform... along with several other VAG cars)
As well as the comfort rain closing for the sunroof here are just some of the things that can be done:
Enabling refuel quantity in the maxidot
Enable DRL menu in the infotainment (so you can turn them on and off)
Enabling fan (blower) speed display in AUTO mode (as std when the heater is set to AUTO the fan speed LEDs are blank)
Enabling Traffic Sign Recognition on models with Lane Assist
Turn on Rear DRLs (with front DRL and 'eyelashes' if required)
Heated seat level memory - Lets the car remember the last used heated seat level (currently it only remembers for 10 mins)
Changing the upper speed threshold for cornering fogsPermanently Disable Start-Stop
Driving mode display on maxidot
Disable tailgate beep
Automatically change clock to summertime
Activating High beam assist (not tried with LED headlights yet)
Activating alarm chirps locking/unlocking (and lets you turn them on and off via the infotainment screen
This list is not exhaustive, there are also a few things some will see as pointless.... we are all different so please resect that.
