I would like to retrofit LED headlights at my Kadjar 2019. I had already installed them, but unfortunately the control units are not driven down when the vehicle is parked. So in the morning the battery is empty. The Renault dealer, where I bought the car, told me that there is no idea about it. But one could put a technical request to Renault Germany and thus to the technology. Said done. Instead of after the specified 3 days the answer was 1 month waiting for itself. Namely, that also the technicians have no idea. Someone must have programmed the main control unit and know what to reprogram to get the things running. In the meantime, exactly my model already exists serially with LED headlights. Nevertheless, they don’t catch that. At VW it was easier to rebuild, computer to tell the control unit what was new and good. Maybe someone here knows with the programming on a Kadjar/Renault and can help me.
