Help. Headlight got flooded and I think I bricked it.

Hey guys. So I inadvertently drove through some deep water in my m3. Got an idrive message telling me my low beam was out and so was the adaptive headlights. Ordered a new xenon and it came today. Took off the back headlight cover, and water poured out... great... Put in the new bulb and it didn't work. Bottom half of the motor was underwater. What are my options as far as replacing the headlight is concerned? Do I have to replace the circuit board at the bottom of the light and the motor? If I do that, will there be coding required? Thanks.

Would the circuit board / adaptive headlight control unit be responsible for the low beam not working as well? Or would that be a ballast issue?

Is this what I'm looking for ^ ?
