Engine Drag Torque Control (MSR)
When the accelerator pedal is abruptly released or in the event of unadapted downshifting to a lower gear, the MSR function maintains stability on the rear of the vehicle.
The MSR function is activated at vehicle speeds above 15 km/h to decrease strong load changes through a brief engine torque increase by increasing the Valvetronic lift, advancing the ignition timing, increasing the injected amount of fuel, etc.
