[399trouble-6]

Hi guys,

I recently got an X6 G06 M50d coming from X5 F15 same engine.
The car has 118,000km and the second I tried it, it had a vibration happening only when reaching ~40kmh and going away when reaching ~60kmh.
I thought I would fix it fairly quickly with some tyre work. I was wrong.

It happens only when accelerating from 40 to 60. It doesnt matter full, mid or low throttle. You release the throttle it disappears. Changing gears midway doesnt help.

Here is a list of every service performed on the car and the problem is still present.

New tyres (it has 22') Pilot Sport 4S back Pilot Sport 4SUV front.
Did the wheel alignments and all there is to the wheels and tyres.
New front control arms
New front wheel bearings
New front left drive shaft
New front and back propeller shafts
New transfer case
Changed the rear differential fluid
Changed the transmission fluid
Reset the differential and transmission values.
Injector values are good.

Still nothing. Right now my next step is changing the EGR as when I got the car it had an error saved for the EGR, I cleaned it and the error went away so I am thinking of changing it for a new one.
Note: Very randomly the car vibrates on a standstill. Not when cold. Its very random but maybe it has something to do with the vibration.

Any suggestions what might cause the issue would be appreciated.
