Problems with Mercedes Vianovito: Engine Light, Unsteady Engine and Black Smoke

Hi all, I have a Mercedes Vianovito and am experiencing some problems. Firstly, my engine light is on constantly. Also, the engine seems to be unsteady and I have noticed black smoke coming out of the exhaust pipe on acceleration. I received an error code P0069 which suggests something with MAP barometer pressure corrolation. Can anyone explain what this means and what could be the cause of this error? Thanks in advance for any help!

The error code P0069 indicates an issue with the Manifold Absolute Pressure (MAP) sensor or its correlation with the barometric pressure sensor. Start by checking the MAP sensor for any visible damage or loose connections. Ensure that the wiring and connectors are secure and free from corrosion. If everything looks fine, consider cleaning the MAP sensor with an appropriate cleaner. If the problem persists, it might be necessary to replace the sensor. Let me know how it goes or if you have any further questions!
