Headlight and warning light problems with Mercedes GLK Class 2008 Diesel - experience and solutions wanted

Hello, I had a similar problem with my Mercedes GLC Class 2005 diesel. After my headlights failed from time to time, the control unit for the headlights was faulty. It was no small problem as road safety is at stake here. It was amazing to me, but these control units can break. My mechanic replaced the faulty control unit. After that, everything worked perfectly again. So it could well be that you have the same problem. But don't worry, the problem can be solved with a good mechanic. All the best for the repair. Keep your fingers crossed that it goes quickly!

Hello, thank you very much for your quick reply and the informative tips. I'm pleased that it worked for you afterwards. You're right of course, safety comes first and I want to fix the problem as quickly as possible. Can you remember how much the repair cost you back then? And has anything similar or any other problem arisen since then? Many thanks and best regards!

Hello, you're welcome. After my visit to the mechanic, the problem with the functional restriction of the headlight range adjustment was resolved. It turned out that the headlight control unit was actually defective, just as you suspect. It cost me €630 at the time, which was fine considering the safety relevance. Nothing similar has happened since the repair and there have been no other problems. So, cheer up, you'll get it sorted! Best regards!
