Hello fellow BMW owners.
I need your help with diagnosing an issue with my F25 / 2016 BMW X3 20d M-Sport.

The bootlid used to close automatically with a button which is located on the bootlid. Something has gone wrong as now it only closes up to 80% and then stops with upwards jerk. The folding arms are also make whirring noise which is louder than usual.
After this, no matter how many times I press the auto close button the bootlid doesn't close any further and just jerks upwards. So I have to push it really hard by hand to close it.

Opening the bootlid is working just fine with the remote control and the latch above the registration plate area.

PS. I have noticed another thing which may not be the cause of this issue (but I am mentioning in case it is) is that after forcefully closing the bootlid, the gap between bootlid and the car body is much greater on RHS as compared to LHS.
