Whistle on cold start?

[Dan.Payne]

When i turn the car on from cold i get a slight whistle until the car is warm? Ive got a boost gauge and it appears to be boosting fine but get 30psi vac is that right when off the pedal?

Did a search couldnt find anything

Its cool pal I think everyone has the same worry when they first get a Cupra! Something to do with a secondary air pump or something like that! Completely normal.

ahh good.

it sounds more like a vaccum cleaner than a whistle, you might just have a small leak in the pipe (dont worry about it, its only turned on for a few mins, i usually sit idle until the noise goes, i find the car very lumpy to drive otherwise)

Mine sounds awful when the secondary air pump is running. lumpy and sounds like the exhaust is blowing. You'll notice you don't get any boost at all while it's running. Goes away after a minute or so

as done mine, car idles fine but sounds like the exhaust is blowing around the CAT area

pull the pipe off your airbox and put your hand over the end, the noise goes, just a poor airflow on the pump makes the noise bad
