P3082Diagnosis information - DME (DFI)
Coolant temperature stuck (stuck)
NOTE:
The fault is detected if the coolant temperature at engine start was more than 35 °C (95 °F) to more than 75 °C (167 °F) (depending on time since engine was switched off).
(e.g. off period 6 h --> Coolant temperature when engine starts more than 75 °C (167 °F)
Diagnostic conditions
- Time since engine off more than 6 h
- Intake air temperature when engine starts less than 55 °C (131 °F)
- When the engine starts, the ambient temperature may differ from the intake air temperature by a maximum of 10 °C (18 °F)
- Engine running more than 30 s
Possible fault causes
- Loose contact or corrosion on connectors or lines
- Coolant temperature sensor faulty
- Thermostat faulty
- Influence by engine-block heater
