What does Audi A1's Gearbox Error Message mean?

I recently purchased a used Audi A1 and noticed that a gearbox error message would appear periodically on the dashboard. What does this message indicate and what steps should I take to address it?

The gearbox error message is typically an indication that there is a malfunction in the transmission system. It is important to have this addressed as soon as possible to prevent any potential damage to the transmission.
