NOTESPriority when dealing with a number of faults:
In the event of a combination of faults DF052 and DF026, DF027, DF028, and DF029,
the fault finding procedure remains the same in order to determine the faulty injector.
Special notes:
The engine stalls when the fault appears. The level 1 warning light illuminates along
with the message Faulty injection.
Switch off the ignition, check the condition and connection of the injector connectors.
Repair if necessary.
Switch off the ignition, disconnect the injectors (or the injector identified by DF026, DF027, DF028, DF029)
and switch the ignition back on.
Using the diagnostic tool, check for changes to DF052.
Is DF052 present or stored?

Special notes:
If fault DF114 is present: the engine is unstable and may even stall. Starting difficult or
even impossible when cold, smoke emissions and loss of performance possible. On
status 4.DEF, the level 1 warning light illuminates with the message Faulty injection
displayed on the instrument panel.
Conditions for applying fault finding procedures to stored faults:
The fault is present with the engine running.
See Technical Note Wiring Diagrams of the vehicle concerned.
Check the connection and condition of the EGR valve connector, component code 169.
Check the connection and condition of connector B (brown 48-track) of the injection computer, component
code120.
If the connector or connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check for +12 V on connection 3FB2 of component 169.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check the insulation and continuity of the following connections:
–3GB between components 169 and 120,
–3FB2 between components 169 and 1337.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
