All good. Yes definitely the proximity sensors. goes off at slow speed sporadically.
i noticed that they robbed the original bar of the mounts and cut them to fit the bar, pretty disappointing to be honest, and now proving to be quite frustrating.
so when standing at the front of the car looking at the plate, it is the front left sensor (drivers side), not the farthest from the numberplate.
This photo is how the sensor sits when fully installed flush etc. this is the position that also results in the sporadic beeping. sometimes its fine other times its going off frequently until i re adjust. its clear its on the threshold.

This image is how i have placed it now (slightly in and what feels like it is aimed slightly more up). it has helped significantly, but got a couple of beeps today again.
