So typically after I posted this on the forum it went away. Which then led me to belive that this is a cold only issue, so next day I have been out with the car and nothing. It took a few days for it to come back again, and this is what I am getting (See attached). It is when the revs are dropping, It doesn't record well. I wondered if it was a known issue as my friend as something slightly similar on his EA888 Seat. I have had a lot of cars, turbo, supercharged, modified and it is not a "normal " sound. I will investigate further, it might be one of those thing that drives me mad. Buzz Noise VRS.wav

VAQ diff not serviced yet, it is coming up to 30k and I was going to book it in at that point. From what I can see they are not often serviced properly so I might end up doing it myself to make sure the filters are cleaned. Looking at the car it seems to be a cold engine issue as i could not replicate it when the car was warm

I am just going to take the car out and try and get an audio clip of the noise in question. My thoughts were pointing towards the Recirculation Valve or something Vacuum related, as vavuum will be highest on overun. Thanks for the comments thus far and I will be back shortly.

New to the Octavia world so nice to meet you, I have a VRS 245 (2019) which has an irritating noise when lifting off the accelerator, it is a kind of buzzing / mooing noise when the engine is on overun and coasting with the revs dropping. I get the same noise when out of gear, so it is an engine-related noise rather than transmission. Car is standard at the moment and acts as the "family sensible" car of the fleet, I am really enjoying the drive at the moment though, great all rounder. Thanks in advance
