Hi Lads
Im not involved in this but just want to mention that the optical display for rear parking sensors can be turned on via VCS.
I've done it for a friend who has a Experience with only rear parking sensors. simple change in VCS and he now has a optical display, all be it just for the rear, but im sure I read somewhere that it was another code change to show the full car.
it even just shows the rear. I know it doesnt help with the front problem but just thought I would share.
cant post links yet but its on a site called stemei . de
just navigate to coding, Seat Leon F5, and then get google to translate and look for "Activate Parking Aid Visual"
