SL/R230: Coding out COMAND - What am I doing wrong?




I also have an aftermarket radio; it takes some experimentation with the left steering wheel buttons and the "+" and "-" to access the clock and change it. My car is at another location now, or I would write up the exact steps.








Go to:
"Control units"
"Information and communication"
"ICM - Instument cluster with maintenance interval display"
"Diagnosis to plant specifications"
"Control unit adaptations"
"Control unit adaptations (variant coding)"
"Variantenkodierung Werkseinstellungen" (meaning: variant coding factory settings)
Scroll down and set "Uhrenverstellung" (meaning: clock adjustment) to "enable" -- It's about half way down.
It's not immediately available. You'll need to force the instrument cluster to restart. In my case, I added Distronic (which I don't have and it was the first one listed at the top of the control unit adaptions section
) and set it to PRESENT. Coded it to the ECU. Changed it back to NOT PRESENT and coded back to the ECU. After that it was available in the instrument cluster settings in the dash. Powering off the car then back on might work but I'm not sure if the ECU truly powers off immediately. I'm sure if you left it for an hour or so, it would have had the same effect.
