BMW Fuel Pipe Seal
This bulletin applies to 2018 BMW 320i xDrive vehicles. The fuel filler pipe seal is possibly not mounted correctly and/or poorly mounted over the wheel arch flange.
If incorrectly installed, water may leak into the luggage compartment.
To inspect, remove the right rear wheel arch cover following repair instructions REP 51 71 041. Visually inspect the sealing lip of the fuel filler pipe seal to ensure that it is correctly and completely pressed into the vehicle body.
If not correct, using the rubber tabs of the seal, pull the seal inwards to completely install. Ensure that the seal is completely seated around the entire perimeter.
