Skoda Octavia 4, 1.5, MHEV, 2022 user here. 
 

From time to time, in 1st gear mostly (occasionaly in 2nd as well), I get the squeling noise that you will hear in the video attached (in the first 2-3 seconds).

That noise might appear when slowly accelerating, but I heard it when I released the brake pedal and let it “crawl” for 1-2 meters, without pressing the acceleration pedal. 
Everytime that I heard the noise, the car used to be stuck in traffic jams. When the traffic is clear, there would be absolutely no noises throughout the trip. 
it can be heard whether I am driving in D or S. 

Also this noise appears completely random, and doesn’t repeat at the next red light or on the same trip. There are days when this noise is not reproducible at all, making the defect hard to be identified at the dealership so that they can actually work on something. 
 

Do you guys have any idea on what may cause this problem? It drives me nuts when I hear it.

For anyone that has a similar issue… 

i had the clutch replaced on warranty. It was defective from factory.
