I thought I'd write up the installation of parking sensors on the new Leon for those that are contemplating it. All in all it took around 4 hours, although once I know what I'm doing it should take about half that !
ok well similar thing ive mounted a parking camera and screen in my
leon mk2 1P. it owrked ok for a few days i also found out the hard way about the blue black grey/black wires,the wire u think it would be is actually for the rear fog light it baffled me for ages untill i thought i would test all the lights untill i get a reading.anyway now when i revers the relay unit buzzes away like its on fire ie it keeps swithing very fast and i dont know why.the rear light wont come on atall now even once ive reset the dashboard fault light. so i have no reverse light atall with or without the unit hooked up. the strange thing is the reversing camera will work with the car turned off and into reverse but when the engine running it will make a buzzing sound on the relay and wont operate the camera or screen properly.
does anyone have any idea as my waranty ran out 2day and its just come out the garage and they wont look at it bewcause i have modifed it.lol
PLEASE
HELP i do know alot about electronics but just dont know what the hell is wrong with this as it was working fine for a few days. the relay is fine i tested it and used another to double check.the screen is ok as it works ok when the engine is not running and the same with the camera. but no reverse light atall,bulb is ok even tried clearing the DTC's (fault codes cleared) but as soon as i put it in reverse the fault light comes up again
