ZF Ecomat OPEN COVER - KickDown & Retarder (Setra S415NF)

Little drive with a Setra S415NF €4 OM 906 hLA engine attached to a ZF Ecomat gearbox (should be a 5HP500 but I'm not sure). Gearbox cover has been removed for better sound. In first part, the sound during acceleration (upshifting) and in the second part, the sound of the hydraulic retarder. Sound has been recorded with a Tascam recorder to obtain the best quality possible. Vehicle : 2009 Setra S415NF €4, engine Mercedes OM906hLA 210kW - 285ch - 1150Nm (When the turbocharger was working...) ENJOY ! 167
