    My R231 SL was serviced on 22 June 18, just before 3 year warranty expired on 25 June 18.

    I didn’t use the car until today .. within a few seconds after start up and headlights on (underground garage so headlights come on), I get the above error

    turning the car off and on again does not resolve it

    any ideas? is this going to be expensive? windscreen where the camera is is clean

    dealer did not reset service indicator so car showing “service A due” .. was wondering if this is related?

    I tried resetting service indicator but the car won’t allow it, saying reset “not completed”

    I had this when I first bought my car, just before which a new screen was fitted. Turned out that the camera that detects oncoming headlamps and then dims your own was not seated correctly in its holder. Remove the over head panel cover and check the connector to the camera and that it is mounted correctly. It may have moved

    I had a new windscreen fitted 3 weeks ago, 2 weeks before the service ... but the error just came on today

    Who fitted the new screen?

    The camera should have been recalibrated when the screen was fitted.

    autoglass.

    Camera was recalibrated as speed limit assist, lane Keeping Assist all works. There is only one camera on the windscreen

    MB thinks I need a new headlight or a new headlight control unit. Can’t be sure until they take the front bumper off.

    MB may cover under goodwill. Otherwise, big ouch as new headlight is around £2000 plus £600 labour

    after 2 weeks of error messages, the error message disappeared yesterday

    Half the time MB are just guessing, always the most expensive guess first
