    Any thoughts or advice is welcome! I am hoping it is just that a bulb has gone, but I'd have expected a message that the bulb is gone rather than a message about the ILS. There's also a message that the Adaptive Lighting is inoperative. Funny enough the cornering lamps that are part of the ILS do still seem to be working. Thanks in advance for any ideas...

    I'd change the failed xenon burner and see if the message goes away. No point worrying about what may not be an issue when there's an obvious fault / solution present.

    Thanks! Tried swapping the bulbs and found that the bulb was not the problem, so a useful first check. Given that it was not the bulb that meant time to go and get plugged into Star. Turned out to be the controller unit (which was sitting in a puddle of water so showed up a failure in the headlight housing too). Result = a whole new headlamp, ouch :( Both headlamps do seem much brighter now though, so I think the controller must have been on its way out for a while.

    Thanks for the update. Sounds like an expensive fix, but at least it's now sorted :thumb:

    I have the same problem. Water in the control unit and in the headlights. Is this not a faulty seal causing water to be in the headlights and the control unit? How do I put a claim to Mercedes UK that the seal should have been faulty or else where do all this water come from?

    Yes, correct, this is ultimately due to a headlamp seal failure. As my car was over 6 years old at the time I did not look to MB for help or compensation. All diagnostic and repair work was done by my trusted independent.

    Depending on the age of your car I guess you could approach MB for costs (especially if you’re still under warranty). To do that you’d have to take it up with your MB dealer, who may (or may not) be helpful. How old is your car and have you any remaining warranty? Good luck, anyway, and also welcome to the forum!

    Car is almost 4 years, so outside the 3 years warranty

    Might be worth asking for MB contribution , nothing to lose

    Let us know if you get any joy from MB, it’s always nice to hear of the few occasions where they do offer some goodwill.
