2015 308 Parking Sensor

Hello Friends, I own a 2015 T9 Chassis 1.6 BlueHDI Eat6 Active Package 308. The vehicle has parking sensors but they are not working. And the parking sensor activation/deactivation menu is not visible on the Smeg screen. Where is the parking sensor control center (brain)? Can anyone with experience with this issue help me?

Hello, sir. This is a problem I've heard a lot about, but I haven't heard many solutions. As far as I remember, a user was told that the Smeg ECU and parking sensor ECU suggested by the service center needed to be replaced. You can find the part number at the link below. From what I can see, it looks like the left side trim is under the trunk. https://partsouq.com/en/catalog/genuine/locate?c=PEUGEOT00

Thank you for the information, sir. Thank you...
