What is this noise?

I’ve got a 2019 G30 520i and have owned it for about 6 weeks.

I’ve noticed 2 noises, one of which I have been able to record and I will try and attach it below. It seems to be coming from the front near side corner of the car and when I opened the bonnet it it’s behind or around the headlight/coolant reservoir area.
It sounds almost mechanical, like something it trying to “fire up”.

What do you think it is?

The second noise is harder to record as its infrequent. It seems to come from around the rear offside corner (petrol cap/wheel arch/rear door area) and happens when I unlock the car and approach it (but not all the time)
It’s like a grinding of a gear type sound. Really strange sound for that area of the car. Any ideas what it may be?

I assume with it being 2019 model, that despite it being 2nd hand, I am able to return it to BMW under warranty for them to have a look?

Apologies if this all seems basic or obvious.

Many thanks.

I have a similar noise. Did you find a reason?
Anybody having a similar noise? Is it normal?

Is the car on? When does the noise happen?
Perhaps the grille flaps motor?
