Priorities when dealing with a number of faults:
–Deal with all the other faults before fault DF859
Special notes:
This fault is activated if the injector recalibration has not been carried out since
1800 miles (3000 km).
Leave the vehicle to run at idle speed until the engine is warm.
When the engine is warm (PR064 COOLANT TEMPERATURE above 77˚C), carry out the following test drive:
–Drive at a speed of up to 30 mph (50 km/h) and change into 5th gear.
–Stay in this gear and perform 8 accelerations from 30 mph (50 Km/h) to 54 mph (90 Km/h).
–At the end of driving: without switching off the ignition, allow the vehicle to run at idle speed for at least
10 minutes.
–Switch off the ignition, and wait 30 seconds.
–switch on the ignition, check that the fault is stored and clear the fault.

If there is water present, bleed the diesel filter.
If there is a great amount of water, run the first part of Test 13: Diesel fuel conformity check (Is the fuel cloudy
or does it separate into 2 parts?)
Check the connections of the water in diesel fuel sensor, component code 414.
Check the connections of the engine management computer grey connector, component code 120.
If the connector(s) are faulty and there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the connector(s), otherwise replace the wiring.
With the ignition on, check for +12 V on connections 3FB1 or 3FB2 (for New Twingo) or AP15 (for Kangoo 2) of
component 414.
Check for earth on connections M or 3WU (only for New Twingo) of component 120.
