Post-wash condensation in headlamp assembly

My new-to-me '11 535GT came out of detail with some condensation in the driver side headlamp assembly. Cleared up overnight. Is this an issue I need to get the dealer to resolve quickly?

Thanks in advance.

Probably not. Make sure the rear covers on the headlight assemblies right and left are tight and have their gaskets in place, as well as the Angel Eye cover. The main and pulse main beams have square covers with soft gaskets, and the angel eye itself has an o-ring, and the cover also has a secondary o-ring. This is from a 2007, 760Li, yours may vary.

You will find a lot of shoddy work by dealers who leave things loose, not mounted properly, etc. The assemblies themselves look as if they are completely sealed, so any water inside is due to an opening somewhere that's not designed to be there.
