Strange Buzzing/Whirring noise coming from car when off-road

[Aibak]

Hi Guys,

So for some context, my car is the AWD Long Range Model 3.

Not sure if anyone else has experienced this, but I'm on holiday in Scotland and the drive/path to the cottage is littered with massive potholes so I try to be cheeky and drive half on the grass, half on the road, just to avoid causing any damage to the car.

But I've noticed this strange electrical whirring noise that comes when the tyres go on the grass, I've had the car for 6 months now and its the first time I've heard this noise (also the first time I've taken it on grass I think).

I thought that it might just be the 4 wheel drive system doing something to stop the wheels from slipping, anyone have any clue if I'm right or wrong?

Thanks!

I have driven up plenty of tracks in Scotland and not noticed this.

I have driven up plenty of tracks in Scotland and not noticed this.

It's absolutely fine when going up and down gravel/dirt/rubble like tracks, it's literally just when 2 wheels are on the wet grass and the other 2 are on the road.

I'll try and roll my windows down next time to see if I can hear if the tyres on the grass are slipping at all.
