Fault Information


Fault Code Description
A positive continuous exhaust-gas recirculation valve position control deviation is detected if the control deviation lies above the maximum limit value.
The limit value is calculated using the position control setpoint value and a characteristic curve.
Fault Code Conditions
General Conditions Monitoring of steady-state control deviation only takes place when the following preconditions are met:
- The exhaust-gas recirculation valve monitoring reports an enable condition or a switch-off condition.
- The adaptation of the exhaust-gas recirculation valve is not active.
- The coolant temperature is greater than the limit value: 16.96°C.
Control unit voltage: 9.5 V to 16 V.
Terminal Condition PWF status: Driving

Terminal Condition PWF status: Testing-analysis-diagnosis

Terminal Condition PWF status: Residing

Driving Conditions
Fault Time Condition
The fault is entered if it is present for longer than the following period (debounce time): 2000 ms
Service Plan
For electrical EGR valve:
1. Check line and plug connections
(actuating wire of the exhaust-gas recirculation valve)
2. If wires and plug connections are OK:
Replace EGR valve.
For pneumatic EGR valve:
Check vacuum system between following components and repair if necessary:
- Vacuum reservoir.
- Vacuum fuel tank.
- Pressure converter for bypass flap of EGR cooler.
- Vacuum unit for bypass flap of EGR cooler (diaphragm may be torn).
- Pressure converter for EGR valve.
- Vacuum unit for EGR valve (diaphragm may be torn).
Look out for porous/cracked hoses!
If the vacuum system is OK:
Replace EGR valve.
