1.5 150bhp petrol whistling noise

[Nozza]

Hi all.

got a 2020 Leon st with DSG box, I seem to have a whistling noise coming from the engine, it’s noticeable under load but doesn’t happen when revving the engine in neutral, further up the gears the sound disappears, I don’t suppose anyone else has had this issue at all? Took it to dealer and they couldn’t replicate it, so told
me to record it, but thought I’d ask on here, thanks

Probably a boost leak when under load. Check for split and loose or damaged pipes

thanks for that, I'm going to have a good look over the car to see if there's anything untoward.

Shouldn't that be the turbo spooling?
