I was walking up the drive today and noticed a small 6 pin plug dangling under the back (when side not back of car side) of the rear bumper drivers side (RH drive), and idea what it might be for?

Will try and take a picture tomorrow

Parking sensor harness? Do your parking sensors still work?

No, when I had my stereo replaced they said it was a reversing camera or sensors, couldn’t have both (be great to get them working again that’s for sure, really useful, more than a camera I reckon)
