DF059 appears on the diagnostic tool when the engine management computer has detected a fault during the
combustion phase several times in succession.
Several components may be responsible:
– the piston rings,
– the piston,
– the valves,
– the injector,
– the heater plug sealing.
If the fault is present:
– remove the injector concerned,
– if there is no obvious fault in the way the injector has been fitted (notably the injector washer), swap the injector
with another from the engine.
– Run commands SC002 Enter injector codes and SC036 Reintialise programming and follow the procedures.
– Restart the engine.
– If the injector concerned produces another combustion misfire in its new position, replace it.
If the fault is stored:
check that no customer complaint has been declared; clear the fault and carry out a road test.
If the fault is still present, apply test 10: Incorrect injector operation.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition until the end of the power-latch phase, and carry out a road test
followed by a check using the diagnostic tool.
