Map-Controlled Thermostat

The map-controlled thermostat allows the engine to be cooled relevant to operating conditions. This reduces fuel consumption by approximately 1-6%. The electrical connections, the design and the map-controlled thermostat response have been enhanced. The map-controlled thermostat function is the same as previous engines (M62).
