Changed wheels, tyres, drive shaft, propshaft, wheel bearings, diff. The most obvious things but didn't get anywhere.
The only thing left was either the transfer case or flywheel.
One BMW specialist told me the same thing, wait till it gets worse and maybe it would be easier to diagnose. But it got to the point where it was getting bad to drive normally and felt like something was going to break.
Unless you manage to find the cause it maybe a case of swapping parts until you hit the problem.
I ended up buying another 4 series but this time with the auto box as the drivetrain will be slightly different. Hopefully this one proves be more reliable.

So I bit the bullet and sold the car. Purchased a 2017 340i xDrive with 20,000 miles. I wanted a car with enough miles to expose likely issues.
This one rides and runs smoothly. There is one thing I do not care for though... but I may start a new thread about "Highway Drone" at 55-60 mph - horrid, loud vacuum cleaner like sound from the engine bay in top gear / ~12-1400 RPM when applying mild throttle. Really not very BMW like.
