Hi guys! Newbie here, recently purchased a 51 plate X5 E53 the parking sensors aren’t working at all on the front or back when selecting reverse there’s no tone but the pcd light flashes I’ve listened for clicking and none of the front or rear ones click any ideas where I go from here? I’m female so if you could simplify it for me that would be great - and hold the learn to reverse jokes 😉 I can reverse but my space is the most awkward one in the world! thanks guys
