@fabulatuaest and
@Antcha Member AlanHo's i30's were fitted with sensors provided to Hyundai by a firm called Cobra. Cobra have been taken over by Vodaphone and they are now called Vodaphone Cobra.
A laptop loaded with the Cobra software can be plugged into the control box for the sensors. Each sensor can then be adjusted for angle covered and range (sensitivity).
His dealer could not do it - so they went to an independent cobra technician who has fitted Cobra front sensors to 3 of his cars.
Not sure if the Sensors we are talking about here are the same, but may be worth asking.
