250 Parking Sensor Part Code

Hi,

I have a parking sensor not working, looking at alternative parts but ideally need a part code to match up as there appears to be a choice - this is for a rear outer (painted ones) parking sensor, not worried about being painted just a code so I can cross reference 3rd party items.

Thanks

 

Thanks - I’m even more confused on what part number I need now though!

 

I think outer right but I might just change both outer ones to black as probably easier than getting one painted white.
