N62 parking system fault?

[StevoAmigo1]

Hi guys does anyone know which sensor the outer right rear distance sensor is? I’m trying to locate it as my reverse sensors aren’t working it’s got a fault code of b122b95, it’s been like this since owning the car over 2 years ago! I’ve seen a video where a guy sprays the sensors with wd40 to repel any trapped water inside the sensors! Do you think this could work?

Thanks im advance
