CLS55/M3

Hey guys, quick intro..just recently bought a 06 CLS55 with 50000km form a MB dealer, MB Extended warranty expired this month, very unfortunate
But still have a MB Powertrain warranty for one more year

Well just the other day my front right xenon headlight stopped working. I changed the d2s bulb and it still doesn't work. No flicking before it went out, It was working fine before the car wash, right after the wash as I turned on the car two message appeared (low right Bean and Active headlamp currently unavailable)

Any ideas what it can be before I make a trip to the dealer?

Did you make the trip the dealership?

It was the ballast, which was corroded, they said it was due to water damage and somehow water got inside.
