Evening, I'll be disconnecting the battery in the morning and will report back. Flashing the high beam a dozen times clears the error. Also the last vehicle check report shows rear headlamp levelling sensor rod seized. Maybe a cause. I'll check the directory if battery disconnection doesn't do the trick. Cheers Karl

Hi Dave, Many thanks for your quick reply. I've checked and cleaned the camera and will disconnect the battery tomorrow as suggested. The high beam assist seems to work as it should turning on and off, although it does turn high beam on in what I would consider quite well lit areas. High beams light the road as you'd expect. Just the 2 warnings of left high beam failure and adaptive failure. Main dealer didn't want to know when under warranty. Independent said LED failure - we can get you a new unit for £2k. Not convinced as it seems to work despite the warnings. Will get a 2nd opinion. Best regards Karl

Hi all, My 2018 435d is coming up with high beam failure / adaptive LED failure warnings but the high beam seems fine. I don't know how to check the adaptive function but visual inspection of the high beam shows it is working and it's passed 2 x MOT's. On the last service I was told one of the LED's had failed = £2k for a new unit. I might be clutching at straws but with high beam working that's making me think (hope) the warning might be bogus? Is it likely to be a new lamp unit needed or is there something else to check first? All advice appreciated.
