Dear community, to the history: – about 1.5 years ago increased consumption recorded (about 7L/100 km) – about 1 year ago the engine goes into emergency run – thereafter DPF changed, additively changed, air hose from turbo to air filter box renewed – shortly afterwards air filter and fuel filter changed – turbocharger with a mirror looks at possible damage. Unfortunately nothing striking found. Currently the moose finally consumes only about 5.5 L/100 km, but: – it reaches a max. speedy 160 km/h in 5th gear and also in other gears it rotates up to max. approx. 3500 rpm – after the clutch is kicked and the speed drops, especially between the 1st and 2nd gear, funny air turbulence noises come from the engine compartment, as if the pressure removed by the turbocharger could not find a way out – errors were read several times by Volvo Werkstatt but found nothing Did you find an idea which caused the reduced power and the noises vehicle data: EZ 11/2007, MJ2008 1.6D, 109 hp, km-Stand: 232000 km
