Had an issue with my reverse sensor being knackered, done the click test and its the n/s corner.
My sensors are at the bottom of my rear bumper, they're circular with a rounded off rectangle within them (the actual sensor i presume).
Whats the part number, real OEM just shows the colour coded ones built into the bumper.
EDIT: I should state what the issue is really lol.
Whats happening is, SOMETIMES it constantly beeps when nothing is near it, however when i reverse up to something it begins to beep as normal (thats why i never changed it, it still works, just beeps like mad when nothings near me lol)
