    Dont know if its a leak or something but just driving home tonight I noticed the wawawa sound lower down at 3K when lifting off. Never had this before, it normally comes in at around 4-5K under full load but this lasted longer and didnt sound the same. Managed to replicate it quite easy and this morning it wasn't happening!

    Any ideas?

    I have noticed that the noises from mine vary quite a lot depending on the air temperature :shrug:

    Never had it before though. No fault codes and couldnt see any change in performance, but I didnt want to hammer it. Is there a link showing how to check the DV?

    Check it physically or via VCDS?

    Was thinking physically. Just been out again and its definitely a change, like a flutter and can happen as soon as the hear the boost coming in. Im 99% sure I have never heard it before!

    Still pulls fine, going to pop the map off and see if its still there or not.

    Well there are a few of us that have a flutter noise at around 4500 but so far there haven't been any negative effects from it. Mine has done it since I put Bluefin on, 29k miles ago.

    Taking the DV off is very easy BTW, just a few torx screws and an electrical connector.

    then noise mine makes also varies depends on the temperature- a lot mroe flutter when its cold, and sometimes a weird buzzing from where its attatched to the came cover, just need to make sure thats tightened.
    These have been quietened down abit though by my heat wrapping.
