did you find the source of these sounds? very rarely I can hear them too when I start the car and before the screen cover is opened

 

Our '21 does this too. I think it is just the plastic clicking where there are seams in the dashboard or around the screen. Not sure there is much that can be done except disassembly and adding fabric (felt?) between the different parts. Maybe some cloth tape between the two surfaces.

 

I have the same. I think it is steering wheel blocking mechanism - in our cars there's no physical key so when you push starter button sth must unlock steering wheel and column.

 

Are we talking about the relay noises when the car is started? Yes, that too.

 

No it's not relay. It's small electric motor in steering column unlocking the steering wheel. There's no physical key so you don't release lock by turning the physical key

 

i thought the wheel is locked by electric power steering, isn't that?

 

I don't think so. I'll try to record this sound

 

In my case this sound often appears while trying to turn on HUD

 

Ok, so that's seems to be something different
