Has anybody experienced the auto headlights just stopping working? Randomly and then they wont work again for the rest of that journey. Have to switch to manual. Next day / different journey they work fine until they switch off again randomly. This is happening regularly for me.

Yes the auto headlights can stop working in certain conditions for me based in northwest france. not had the problem for ages but I winter it happened a few times. I would start off with them working but the they would suddenly stop and sometimes come back depending on length of journey. I am certain it’s related to condensation issues either with the cameras or sensors the condensation arising as the car warms up.

Parkwood's explanation makes perfect sense for misty Ireland. In dark nights of winter I did experience less than expected performance of the autobeam but wasn't sure the reason. Condensation is one of the less obvious barriers between headlights of other vehicles and the EQC computers. I assume in this case problem is unlikely to be from windscreen dust or smearing or external barriers like motorway dividing wall. And interesting that Parkwood finds it worsens with warmup - perhaps condensation is released into the air on warmup and lands on the camera system somewhere maybe even behind the cold windscreen glass. Perhaps turning up temperature and switching windscreen demist blaster on and check ac is on and directing vents to camera may be a theory to try next time or check how camera appears from outside the car. Or given that electric cars generate less heat to keep windscreen warm, perhaps this is an early model flaw that will be fixed in next gen

I think it is an electric car problem as it did not arise with the c or e class. It can be quite temporary or last a little longer in really damp conditions ie rain. It is quite a pain when it does happen.
