Hi all,

I have 2015 F30 330D XDRIVE.

When I drive the car for anything over 15/20 miles I get this vibration coming from the under the centre of the car between the gearbox and the engine. The further I drive the worse it gets where it almost shakes the entire car. Never effects the steering. Car still pulls fine and never down on power.

Vibration stops when I lift off the accelerator to coast or brake. Even at low speeds I can hear this almost flap like sound from under the car once I accelerate again.

I have taken to local BMW specialist and he said guibo/flex disk was fine keep driving.

I have seen people mention issues with transfer case fluid/actuator and issues with drive train maybe even timing chain.

Anyone have any similar issues or any idea what it could be? Thanks
