- Instead of an air volume flow meter, an air mass flow meter is installed. The air mass meter has the following advantages: Automatic compensation for changes in temperature and altitude, no moving parts and therefore even less wear. Air mass measurement principle: An electrically heated heating coil is cooled by the air flowing through it. To maintain a constant temperature of the coil, the filament current changes in accordance with the density and temperature of the flowing air. By changing the heating current, the Motronic system determines the mass of the intake air and, in accordance with this, changes the amount of fuel injected. The intake air temperature is measured by a sensor in the throttle valve connection.
- The ignition system has no moving parts and is therefore not subject to wear apart from the spark plugs, see section "Ignition system".
- On automatic transmission models, the integration of DME and automatic control further improves transmission tuning and smooths shifting.
- Since 1993, six-cylinder engines have been equipped with a camshaft control system, abbreviated as VAN0S. In this case, the intake camshaft is rotated by oil pressure relative to its sprocket depending on the engine speed and load, which gives advantages in terms of smooth idling, torque characteristics and fuel consumption. The DME controls the oil pressure supplied to the actuator via a solenoid valve.
