Ok so for the people that know or have any input on xdrive problems please inlight me in ur opinions, Well i have a 07 335xi 6mt and the car has been having some sort of binding/thumping in the drivetrain which is real bad in the lower gears especially leaving from a stop or having it in a low rpm. There is no clicking or humming noises coming or even xdrive malfunction lights . I know how to drive standard so thats not the case. The clutch grabs excellent and theres no misfires at all.. I pulled fuse #26 to disable the front axles so it would only be Rear wheel drive, and the problem disapears. So its definatly the front driveline. The feeling is hard to explain but think of it as if ur driving and u drop the clutch fast inbeetween shifts and it shocks the drivetrain well this is continuous from say 1200-4000rpm even worse on load , like i said No Noises no lights its really annoying and its making me wish i got a Rear wheel insted . Help if u can thanks guys

You could have a front axle shaft going bad. ECS Tuning has them for $550 with $50 refundable core charge.

disabling fuse #26 disables the front driveline?

Sound like a bearing somewhere if its worse under load

Out of curiosity, how many miles do you have?

Unplug the vtg motor on the back of your transfer case. Drive it. Did it go away? If so it needs a transfer case. They are common causes of what you are experiencing.

Just saw you pulled the fuse. Check all mounts and If the axles look good sounds like a transfer case.
