U Shaped Rear Side Lights

Hi, I have an issue where my rear U Shaped side lights have stopped working in the rear door clusters when lights are switched on. All other lights are functioning correctly, including the lights and side lights in the lower bumper area. When switching on the car, the auto circuit test completes without any issues, suggesting that the circuit is compete and functioning.
Car is a late 2018 i3 with REX.
Any thoughts would be appreciated

The rear lights under the hatch's glass turn off and the bumper lights turn on when the rear hatch is not latched. Make sure that the hatch is shut and latched.

There must be a sensor that detects when the hatch isn't latched, so if the hatch is latched, that sensor could be bad.

Hi Alohart
Thanks you for your reply. The garage think its either software or the control unit. But ill ask them to look into the sensor, It'll be the cheaper option.
Many thanks
