Seat Leon 184 tdi whistle

[scottiedog]

Hi everyone, I've not long owned my 2nd 184 Leon DSG this time an estate. It's a 2018 with 37k on the clock. Recently done to long 3 hours plus drives in it and noticed a whistle ONLY on acceleration at between 65mph and 72mph NO noise before or after. If I lift and dab the throttle around these speeds it's instant noise. Any ideas

What air filter does it have?

It's completely standard so I'm not to sure

Is the panel filter a K&N type? they can make the turbo noises more noticeable.

If you're saying its only between 65 and 72mph - are you saying its vehicle speed related and not engine rpm related? so does the same noise in different gears at that speed?
