Welcome! Please post a photo of the CLA. Sorry to hear about the headlamp. It is under factory warranty?

Welcome. I would also suggest you scroll down the main forum page to find the section for your CLA. You'll find CLA owners in that section who will be more than glad to help you with your question.

The most common problem with Mercedes headlights is related to the fuse. So I agree with the author above me and recommend checking all fuses. Unfortunately, I've never looked into the CLA, but it will be interesting to see what cause ended up causing this malfunction. Or rather not the cause, as the cause is flooding the headlight with water. What exactly was broken did you find out?

Listen to OP description Never ever replaced the fuse for this type of problem, 90% always modules
= Xenon module + LED DRL control module
Buy the PnP typee = no coding needed.
