BMW 535i xDrive wet floor behind driver's seat issue on BMW 535i xDrive

Some BMW 535i xDrive owners report experiencing wet floors behind the driver's seat, which is commonly linked to water leaks caused by a faulty door panel vapor barrier. This issue often arises during or after heavy rain, resulting in water seepage into the vehicle's interior. To resolve this problem, owners are advised to inspect and potentially replace the right rear door panel vapor barrier, as it is likely the source of the water infiltration. Additionally, checking for any perished steering column cover or grommet on right-hand drive cars may help address water accumulation in the passenger rear foot-well. Regular maintenance and prompt repairs are essential to prevent further water damage and maintain the integrity of the vehicle's interior.
