- Open circuit/short circuit to B+
- Starter relay Faulty
Fault effects
- Starter does not rotate
P3081
P3081
Diagnosis information - Control unit DME (DFI)
Coolant temperature Engine implausible
Diagnostic conditions
- Intake air temperature at Engine start < 70 锟斤拷C (锟斤拷F) or Coolant temperature at Engine start < 70 锟斤拷C (锟斤拷F) (See [Information 1])
- Engine running > 3 Minute(s) (without Overrun phase(s))
- none of the following faults stored: Coolant temperature sensor or Intake air temperature sensor
Possible fault causes
- Seal in the Thermostat housing Faulty
- Thermostat housing Faulty
- Thermostat Faulty
- Air in the Cooling system
Fault setting condition(s)
- Coolant temperature Engine < 70 锟斤拷C (158 锟斤拷F), at:
- Diagnosis end (See [Information 2])
Fault effects
- Engine temperature = temperature model (as substitute value for Coolant temperature Engine)
- The fault can be healed only if the thermostat has been tested and found to be OK.
INFORMATION
1. Diagnosis starts under the following conditions: :
- if the system was free of faults before
- Coolant temperature Engine at Engine start < 70 锟斤拷C (锟斤拷F)
- if fault has been previously detected in the system
- Intake air temperature at Engine start < 70 锟斤拷C (锟斤拷F) (Substitute value Engine temperature only for Engine start)
2. Diagnostics is ended,
- to > 3 Minute(s) Engine running (calculated without Overrun phase(s)), and if:
- the calculated temperature model reaches 70 锟斤拷C (158 锟斤拷F) before the measured coolant temperature has reached 70 锟斤拷C (158 锟斤拷F) (fault
entry),
or
- the measured coolant temperature reaches 70 锟斤拷C (158 锟斤拷F) before the calculated temperature model has reached 70 锟斤拷C (158 锟斤拷F) (NO
fault entry).

Diagnosis information - Control unit DME (DFI)
Coolant temperature Engine stuck (stuck)
Diagnostic conditions
- Time since Ignition off > 6 hour(s)
- Intake air temperature at Engine start < 45 锟斤拷C (锟斤拷F)
- Intake air temperature at Engine start = Ambient temperature +/- 20 锟斤拷C (锟斤拷F)
- Engine running > 30 Second(s)
Possible fault causes
- Switch-off time defective = Gateway control module Faulty (See [Information 1])
- 3/2-way directional-control valve Faulty, at:
- Original Auxiliary heater
- Loose contact or corrosion on connectors or lines
- Coolant temperature sensor Engine Faulty
- Influence by engine-block heater
Fault setting condition(s)
