Gearbox Failure Warning

After only a few thousand miles I have this morning had a Gearbox Failure Warning and a Yellow Triangle. I tried to stop the engine and restart but the gear dial stayed up and indicators green, after the second attempt the car restarted and the dial came back to life. Seems to have cleared itself now but anyone had the same problem ????

Thank you Salty for the tip - have to love this forum.

Same problem here on 2014 D4 with ZF 8HP 8 speed gearbox (command wheel instead of stick). Enabling low range, returning to park, then restart fixed it for me.

Symptom
- started car ok, selected reverse and got message "gearbox fault" and yellow triange, message persists when returning knob to P, drive does not work either, engine revs but no movement, outside temperature -15C but no temp related problems before.
- several restarts did not work

Problem
No idea.

Solution
- put knob into neutral
- press low range. Again the "gearbox fault" plus the whole christmas tree lights up with all sorts of failures. Low range does not engage and low range indicator keeps blinking.
- put knob into park. Low range indicator keeps blinking.
- restart car and problem gone

Maybe time for a software update since this was the first model year with the ZF 8HP
