They have checked 4 BMW x3 20d's and all 4 made the noise, the Master Technician then made the statement of all the cars make this noise and its a characteristic of the newer models.
Its so annoying as its a brand new car and the noise is really high pitched, it only happens when the digital cockpit and Idrive screen are active (which is almost all the time)
I guess i have to just deal with it until enough people complain and BMW roll out a fix to make it quieter.

This is not a quick software fix and highly unlikely to be addressed retrospectively. It's a combination of poor EMC/EMI design and ultimately trade offs when selecting hardware and components in terms of performance vs. price.
The simple solution is to crank up the music!
