Buzzing noise on B7 tdi

[saint70]

Hi


I know that could be stupid question but I would like to know answer.
Recently, car started to develop 3-5 second buzzing noise every time when shutting down car.
I can't remember if I heard that noise before..

I wonder is this normal? Could be oil pump, e-brake noise, throttle body noise or just nothing at all...

Just note: This is not DPF noise...

Any idea?
