Unhappy Mercedes W203 kept getting P2043 fault code

Hello to All.

I'm facing this endless power with my W203, M111 kompressor engine where my engine will throw a fault code and it reads as "P0243 - Supercharger Wastegate Solenoid A Malfunction". I have already sent my car to my local indie for further inspections. Parts that has been changed in the past was, supercharger wastegate (the ones sitting on top of the supercharger), maf sensor, air intake hose clamp re-tightening (the one sitting on top of the supercharger), knock sensor, map sensor, both upstream and downstream oxygen sensors, spark plugs, fuel filter. But still, my car having this slight hesitation when i floor down on the gas and it will still throw the same fault code which is "P0243". I am truly seeking for an opinions or any explanations for this issue i am facing. Please anyone be my hero 🙏🙏🙏🙏
