Anyone know or an have idea on what this device is? I'm annoyed that i didn't take a better look when I had the car in front of me and this is the only (very poor) images I have of it.

Its on a 2015 l405 and its in the drivers footwell attached to the side of the centre console and has a wire coming from it up to behind the dash somewhere.

It has a red light towards the top and then lower down it has a set of green lights a bit like those used for wifi or mobile signal indicators whey they go small to large. It also then has what look like and up and a down arrow above and below that green light.

My initial though was something like a x-lifter but my google searching is coming up with nothing that looks anything like it and the image is not good enough when cut out to the likes of google lens reverse lookup to work.

Just thinking that the hive mind on here may have an idea or have seen one before.
