Have recently bought a 2015 dmax and while accelerating the spooling noise is quite loud,but also when i deccelerate and hold light acceleration or almost coast it sounds as if the turbo spools up on its own for a while or until i accelerate again then it drops away and feel a wee surge of power and then is quiet again until the next time. Have had isuzu look at it and they have replaced suction valve and serviced the vehicle. Still doing the same thing,any isuzu gurus have ideas what this could be? Turbo? Egr? Its almost like the turbo spools up and sticks and stays spooling on its own. Bit strange. Will take back to isuzu again .Cheers
