It like goes with the revolution of something... The sound is of like air escaping... ok it goes something like this... Shhh.............shhh.........shhh.......shhh....shhh...shhh..shhh.shhh.shhh.shhh.shhh. I havent had time to look at anything under the bonnet as of yet but just after someone to point me in the right direction. Im thinking boost leak somewhere but yeah not sure. Could my turbo be farked.. with all these turbo failures im worried...Thanks in advanceMike.. Link to comment Share on other sites More sharing options...

I dunno.... The sound occurs with a revolution so imagine a lump on your tyre. It starts off slow but as your speed increases it gets faster and faster. So its an on off sound that gets faster and faster as boost climbs.... It is fairly loud too... louder than any noise my car can make ie: zorst, flutter even stereo depending on the volume....Any other ideas... I guess checking all the hoses would be the first place to start? Will I be able to see if my turbo is damaged if I take off all the piping?Thx for all the info guysMike....

I have used 2 different tuners programs aswell so its not like its the tuners fault. Someone mentioned compressor surge and that it isn't a safety problem.Farking annoying though.
