Powertrain Management: Application and ID
The new N12 and N14 engines on the R56 are complemented by the latest in engine management technology. The previous EMS2000 system is now replaced by two new engine management systems. These systems are the MEV17.2 for the N12 engine and MED17.2 for the N14 engine.
The difference in the engine management designations reflect the engine technology. For example, the "V" in the MEV system reflects the use of Valvetronic on the N12. The "D" in the MED system indicates that the engine (N14) has direct injection.
