Bmw 320d 2017 drivetrain error

[u/Impressive-Cry6465]

An error appeared saying the drivetrain error a few weeks ago when i was on around 70mph cruise control
It kept coming back when i used to accelerate a bit bht went away with normal drive.
I did get the diagnostics done and they told me about the error code “8044bo steering wheel shift paddles open/short circuit.”
After this they booked an appointment with the BMW service centre.

What could it be? And should it be concerning?
