Hello sorry if i make mistakes writing, not my native language. My Škoda makes strange howling sound  when rpm is around 1600  and warm engine. Does not matter what speed or gear only depens on rpm.  Maybe someone had same problem and can tell what should i check

 

 

Does it sound similar to this..

 

 

...or this...

 

 

...or perhaps this?
