Acceleration Squeak

[Heck6r]

I've noticed my car has started to make a very loud squeaking sound on acceleration a while after changing to a racingline intake since then I have now switched to a K&N intake but the sound still appears but is less often than before if anyone has an ideas that would be much appreciated

Can be anything, are you sure it's just with/from your intake changes?
Are you sure the squeak isn't your induction noise...? Hard to explain how it sounds because every car is different.

Its hard to show id film it but it doesn't happen when stationary only whilst driving its definitely not induction noise its a horrible screeching noise I think it might have been the air escaping from a sensor that was in the silicon hose not sitting properly will have to see if problem persists the sensor wouldn't sit correctly in the hose so I elecrtcal taped it up haha if it keeps happening ill get a friend to film so the sound can be heard

First of all - which car have you got? Polo GTI with the 1.4 twincharge engine, or the later 1.8T.

If its the 1.4 then you are probably hearing the supercharger. Suggest you remove the intake and re-fit the original intake to ensure the noise goes away first.
