BMW 550i xDrive wet carpet issue due to defective door vapor shields allowing water intrusion on BMW 550i xDrive

Some BMW 550i xDrive owners report experiencing wet carpet issues, particularly on the rear driver's side, often attributed to defective door vapor shields that allow water intrusion. This problem can result in soaking wet floor carpets, especially around the speaker area, due to leaks through the vapor barrier. Many owners have found that replacing the vapor barrier is a common solution to combat these water intrusion issues. Additionally, some owners notice condensation on windows and wet floors on both the front and rear driver's side carpets as a result of these leaks. It has also been reported that leaking vapor barriers can lead to water accumulation on the rear driver side carpet after rain. Furthermore, clogged drains under the cabin air filter can contribute to water pooling on the driver's floor and rear footwell. If you suspect water intrusion in your BMW 550i xDrive, it is recommended to inspect the vapor barriers, door seals, and drainage systems to identify and resolve the issue promptly.
