Hello people’s. Looking for a bit of help iv got an octi mk2 vrs petrol had it for 6 years now apart from your usual where and tear stuff she hasn’t let me down. It’s got a stage 1 remap which has been on for about 3 years and pulls nice but  the other day I put my foot down and it was boosting but only had half the power and a little whistle  noise  when turbo comes in. it’s not the siren noise u get when the turbo done been there before 😬but running fine otherwise management light came on for a day then went of. Thanks in advance 

Maybe got an intake leak / burst or loose pipe so its not building up boost properly?

 

Any error codes?

 

sounds like a split pipe alright losing boost

Not had chance to plug it in yet mate but will. U can normally hear the resert valve gush when build boost and change gear bit like a dump valve but doesn’t do it now does sound like a boost leak well I hope so lol. Thanks
