NOTE:

For display zone 3:
The engine control module will use the intake air temperature as a replacement value for an engine start (start temperature - replacement value) as soon as there is a malfunction stored in the DTC memory, which affects the Engine Coolant Temperature (ECT) Sensor G62. The temperature then rises according to a model stored in the control module. When the engine has reached normal working temperature a fixed replacement value will be displayed after a certain period. This fixed value is also dependent upon the intake air temperature.

NOTE:

For display zone 4:
The total temperature range is given as the specification. The displayed value must be above ambient temperature.
