Hi guys,
So I have a high pitched whistle/whine noise coming from below the bonnet. My mechanic has tried everything he can think of and spent quite a few £ trying different things. The noise is quite similar to a faulty turbo but this defiantly isn't the case. It's more of a high pitched whistle than a whine. Things that have been looked at so far:
turbo removed and checked - all ok
noise still present with boost pipe off
dfp had already been removed, seals all checked and no issuses
smoke test done revealed a leak in the inlet due to badly blanked swirl flaps -
re sealed and no more leakage.
dont really know where to look next? The harder you rev the louder the noise gets. It's very loud and whistley. I'm going to try and upload a sound clip. Any help would be greatly appreciated. Thanks
