BMW 528i xDrive condensation in headlights causing control module shorts, requiring new headlight assembly on BMW 528i xDrive

Some BMW 528i xDrive owners report experiencing condensation in their headlights, which can lead to control module shorts and necessitate the replacement of the entire headlight assembly. This issue arises when moisture enters the headlight assembly and trails down into the modules underneath, causing significant problems. Owners are advised to check the cover on the back or top of the headlight for any looseness or damage that may allow water to enter and damage the internal module. In some cases, attempts to dry out and reseal the headlight assembly may not completely resolve the issue, resulting in repeated instances of leakage. It is crucial for owners experiencing these symptoms to address the problem promptly to prevent further damage and ensure the proper functioning of the vehicle's lighting system.
