Pulsing noise behind instruments

[Baileythecake]

Hi took my f type into Jaguar to investigate noise at first they had no idea what was causing it then they informed me there was an update in software. Told me it was fixed first set of traffic lights i stopped at noise reappears.
Any body else experienced noise and had it fixed?
Not very impressed with dealer aftercare

In my XJ there’s a couple of fans which cool the gubbins on the screens - the central touch screen and, presumably, the digital dash.

One of them squeaks a bit, but only when the conditions are right, ambient temp etc.

I know the F Type doesn’t have a digital dash, but I wouldn’t be surprised to find a heat exchanger of some sort for all the electronics in there. A fan motor could easily build a pulsating resonance if it’s starting to wear
