Hi all I've seen an answer somewhere on here to my problem but can't find it again. My problem is as follows, when it rains or has been raining (or after washing the car) when I move away all is fine. After applying the brakes all the water rushes off the bonnet and then I get 4 red leds and audible beep constantly from the Parktronic.This does stop eventually when the car has been driven for a while or dries out. Is there a way to stop the sensors getting wet to prevent this happening or have I got a more serious fault. Majority of the time everything is fine.
