The two software lines that run the monitor in the Kombi (Intrument cluster)
are turned off by setting them to nicht active. Somehow when the TCU was
still turned on I got and SOS error on turn on anyway that was defeated
by unplugging the TCU.
If you want some of the functions that the TCU had and the entire TCU or Mulf or
combox is bad and you want to stay factory you need to source a new one
and program it.
