2016 B ClassB200 AMG line headlight issue

[c13tay]

All of a sudden got 3 warnings. Dipped headlight , indicator and parking light all inoperative …. In fact nothing on the drivers side headlight unit is working

Before I start to have nightmares about the cost of a new headlight unit , has anyone ever experienced anything like this or have any ideas ???

Thanks

Chris

Have you checked the fuses?

Yes, checked fuses. Noticed that when I gave unit a bang it flashed on for a while. Took it to local garage, turns out it was ballast unit. There was evidence of water ingress
