As long as there's an analog wire somewhere that goes live with +12V when you turn on the highbeams, you're set. All you need is a relay, or preferrably a "CAN bus compatible" €50 ish wiring kit that really only is a slightly fancier relay that draws so little current the car doesn't know you've tapped into it.
If your car is like mine and doesn't have said wire, you will need a little brain box that wiretaps the CAN bus to detect when the highbeams are switched on. It then outputs a 12V signal for the relay kit.
Small update, 2 weeks ago the automatic headlight height adjustment spat out an error and the lights started pointing straight into the ground ala
Had it diagnosed, the fault came up with the front arm sensor. OEM importer wanted €140+tax for it, at the notion of which we all laughed (including the importer) and they were more than happy to provide me with the part number so I could find it somewhere else. Good news, ebay had a plethora of them with the most reliable seller offering one for €36 delivered. Bad news, it took 2 weeks to get here, but after 30 minutes on a lift, the faulty one is in the bin and the lights work again.
