The invention relates to a method for operating a drive unit (1) for a motor vehicle, which has an exhaust-generating drive unit, an exhaust system (2) that discharges the exhaust gas towards the outside environment of the motor vehicle, and an iris diaphragm (3) arranged for adjusting the flow cross-section for the exhaust gas in the exhaust system (2). The iris diaphragm (3) is arranged in an end pipe (6) of the exhaust system (2), through which the exhaust system (2) discharges into the outside environment, and is controlled to adjust the flow cross-section to a preset value determined as a function of an operating parameter of the drive unit (1). The invention further relates to a drive unit (1) for a motor vehicle and a computer program.
