Buzzing Noise

Hi all,
I’ve got a 2004 Discovery and when I turn the engine off it makes a sort of weird loud buzzing noise maybe 4 or 5 times or so. It’s only just started yesterday so I don’t know if this is consistent but I was wondering if anyone had any ideas on what it could be or how to fix it.
TIA

The EGR valves run through open and closing cycles on shut down.
Also the turbo vvt, but that is with later software.

Yeah. Mine sometimes does something similar. It sounds like an electrical buzzing and comes from just below the radio, which is not related to the EGR shut-down exercise. It sometimes keeps on buzzing until the vehicle goes to sleep.

I put it down to a modern version of the old Land Rover truism that the designers started with a rattle and built a vehicle around it! Smile
