I have an F30 with a 5AG update. It works fine except at low speeds, where the "Lane Change Warning Failure" error appears and it shuts down on its off.

Did you see HC2 ecu? Activate flexray path?

Did you read out with i5тд+? Which dtcs are present?

Flexray line reset and started successfully.
No errors in i5тд, HC2 coded with ё5у5 and written to VCM.

Calculate SVT and check whether the hardware of HC2 is intact with your I-level. If not, you need to code it rising the minimum activation speed.

I have an F30 with that option, I replaced the steering wheel for a sport one that did not have the vibration option, and was having the same problem, system will shut down when triggered.
I had to get a sport steering wheel with vibration function.
You should see an error code on the FEM related to that.

Solved
Increased the minimum activation speed.

C_ZSW_Aktivierunggeschwindigkeit_Funcion_low 50kmh

30kmh is better.
