Fault code
200908 - P323F

Fault text
DME, internal fault, monitoring fuel quantity: ratio lambda
air mass to fuel quantity, correlation fault

Fault description
The diagnostic function monitors internal operations within
the control module to ensure that they are executed
correctly.
(Here focusing on the ratio of injected fuel to the air mass)

Condition for fault identification
Test condition:
The fault is recognized when an internal comparison detects
excessively high deviations.
Potential problem source(s):
- Collateral fault from malfunction in oxygen sensors
- Collateral fault from malfunction in fuel system
- Collateral fault from malfunction in air induction
- Defective DME
Terminal condition: Terminal 15
Voltage condition:
- None
Temperature condition:
- None
Time condition:
- None
Other conditions:
- none

Condition for fault memory entry
This fault is logged in the control module's fault memory if
it remains present for longer than 4 sec.

Action in service
- If diagnostic fault code 0x110001, 0x110002 or 0x110008
is logged, then this fault can be ignored
- Check oxygen sensors, fuel-supply system and air-
induction path
- If the diagnostic fault code has been entered with a
frequency > 3, then replace the DME

Fault effect and breakdown warning
Breakdown notice:
- Allow vehicle to enter sleep mode, then restart may resolve
the problem, although the remedy may only be temporary
Possible apparent symptoms:
- '- Refuses to respond to accelerator
- Pronounced shaking at idle
