That's true German engineering.
Let's see...
Thermochromatic liquid crystal badge, AdBlue level sensor, AdBlue level sensor interpreter module, AdBlue level sensor interpreter module output DAC, analog potentiometer, badge heater input relay, badge heater output coil, three or four associated service bulletins for periodic coil replacement (every 30k miles, or 5 years, whichever comes first), but only on Touaregs destined for the NA market, even though it really needs to be done on all of them.
Sounds about right :twisted:
