    engine have a hard noises when i am pushing gas pedal, engine brake working very bed, (they told me brand new trucks don’t have hard engine brake anymore:))). ) truck is not rolling, when I putting out my leg from gas pedal turbo pressure is going down but RPM stays at around 1500. Transmission not got to ECO MODE. I don’t know what i can do. Two dealerships, They told me nothing is wrong and both charged me 600$
