The part number is 4G8827851F or 4G8827852F (Stabilus POWERISE).
Note
You will need a metal pipe cutter to get inside - mine is branded by TOLSEN.
Caution
These tailgate actuators are equipped with a preload spring. The springs are there to counterbalance a trunk lid weight, and make life easier for an electric drive. However, this seems to make them impossible to play with on a lab desk. The plastic (nylon/polyamide?) planetary gears between the motor and the screw assembly were not designed to handle such a load - they failed in both of my actuators after a couple of runs. This might be an ultimate, i.e. intentionally designed, safety feature of actuators not equipped with an overload clutch - it's better to lose an actuator rather than to harm your body (or the body of your car).
Why is ARR value set to be an even number? This is to have the odd number of levels (remember that we count from 0), and to be able to generate 0 V at the output of the converter exactly in the middle of the range.
I couldn't find the 203K 4424.72 sensor. My educated guess, with a confidence level of (say) 99.9%, is that they are low jitter, 24 V (as for IPR35) Hall-effect latches for automotive and industrial applications, such as APS12203 (Allegro MicroSystems).
Important
The Hall-effect latch used in the actuator has an open-drain output - a pull-up resistor is required.
Don't worry 🙂 Just log in to MyST and hit Alt-K to generate /Drivers/CMCIS/ and /Drivers/STM32L4xx_HAL_Driver/ based on the .ioc file. After a couple of seconds your project will be ready for building.
