Heated Thermostat

Heated Thermostat







As a further measure for controlling the engine's operating temperature, the heated thermostat, introduced on the M62 engine, is carried over to the M52 TU engine. The heated thermostat allows the engine to be operated at higher controlled temperatures during low and part throttle conditions which reduces the fuel consumption of the engine.

The thermostat heating which opens or closed the thermostat to control the engine temperature is controlled by the DME. Any problems will be diagnosed as part of the DME system using the DIS or MoDIC.
