Should not whistle at all, sounds like a boost leak.

sounds like a air leek to me like a hissing whistle sound

dont do it if foot lightly on pedal even up to 6000 revs

but foot to the floor starts hissing / whistle at 2000 revs

but the garage that fitted the intercooler have said its the normal turbo sound

and wont do anything

have had it mapped and a forge dv

but could hear it before the forge was fitted

or are all other vrs quiet when booted

Mine whistles!...........but my turbo's f*****!

Does it sound like a police siren sound or just a whistle?

Could just be an air leak, do you have a boost gauge fitted?

Are you able to get someone to record the noise when you boot it and post it up here?

Might be an idea some of the more knowledgeable guys on here might be able to give you a better idea.

Also check the 2 pipes under the inlet manni they are prone to spliting.

can try and record it on my phone and try and do it

no doesnt sound like a police siren just a whistle

like if you try and whistle through your teeth lol

no boost guage fitted and have no idea where the inlet is lol

sorry no good with cars

know its coming from the right as my partner cant hear anything through the passenger side

just the drivers side

cant hear it when light on pedal and hold it there even up to 50 in 2nd

but if foot half way down upto 50 can hear it in all gears after 2000revs

All VRS and 1.8t cars has a slight whistle. Well certainly when the turbo hits boost.

This is a low level noise and not always heard clearly unless listening. If folks change DV or Air filter for performance one then the whistle will increase louder.

If you had the noise before the intercooler was changed perhaps all is ok. But if the noise is intrusive then that sounds more than just normal turbo whistle. Any decent garage can advise you on this.

When i changed my air fillter for a performance one my car is noticeabley louder while booting it,

Maybe you don't have an issue after all lol.

i have no idea then couldnt hear it when i had the car then had it mapped and could hear it slighly

the chap who mapped it said it sounded like a leak so booked it in to have a smoke test done

they said the intercooler was leaking so changed it

had it back and couldnt hear it as loud at first then got worse

took it back the garage drove it and said its normal

some people say no whistles orthers say yes its ok

car hear it with the window up sometimes

if its the turbo should i hear it when foot slightly on the pedal as the turbo still works but dont hear it when driving lightly

As I stated you can here the Turbo at spool up and certainly more if you have had it mapped as the map will be pushing the turbo harder.

Although I am somewhat surprised you had the intercooler changed due to a leak, this now strikes me as a pipe leak to or from the intercooler. Perhaps the garage when changing the interooler moved the pipes and sealed leak slightly and as you have been driving it, the leak has opened up again. It is all speculative as could be one of many pipes, perhaps check the boost, by hooking up a gauge and see what it is doing to be sure.

Trust me these cars whistle. low level whistle. And you can hear it more with wndows closed. As you can concentrate hearing the engine noise through cabin.

i can hear the turbo spooling up like a deep spinning noise

the noise im hearing is a loud whistle similar to the s2 escort rs did but bit louder

will get the garage to check it again

they showed me the old intercooler and said it had got damaged

i have said i couldnt hear it much when i got it back but has got louder over a few weeks

when i go back they just say its normal without even looking

record the noise and post it here.

I have had a few S1 and S2 escorts and i would say noise is similar as again with the escorts there was a low level turbo whistle. I would not discribe it as deep and loud though.

Go to a better garage and get a second opinion. If found to be suspect you can claim back from the other garage or get them to fix it properly.

will ask at the local skoda dealer in bilston tomorrow see if one of the lads can take it round the block and let me know

the garage put a smoke machine on and said intercooler was broken and leaking

just wondered if that was bad would the smoke have picked another small leak further on

i remember listening for the turbo whisle when i had it and couldnt hear anything

all ive had done since is remap , forge dv and intercooler
