-01 V70 ETM Whining sound (with video)

[Zeeker]

Hi,
Last year I had a problem with my car. The engine just died. Ignition off/on and it mostly started direct.
I cleaned the ETM (poorly), replaced the relay to the fuel pump. Nothing seemed to work. But suddenly the problem went away, until now... The exact same problem

So, I have read a lot about the ETM...
My question is, mine makes a terrible noise. Is it normal? Does it indicates that cleaning is needed, worn out ETM etc?
Any help is greatly appreciated.
