NOTESPriorities when dealing with a number of faults:
If DF069 Selection position sensor circuit and/or DF070 Engagement position
sensor circuit is stored, deal with them first.
Special notes:
Fault warning light comes on.
Improper use of lever when the vehicle is stationary may lead to this fault.
Check that the selector lever is correctly clipped onto the hydraulic unit by looking through the inspection flap
(see MR 411 Mechanical, 21B, Sequential gearbox).
Check if the water in the gearbox oil is due to condensation.
Replace the oil if necessary (see MR 411 Mechanical, 21B, Sequential gearbox, Electric pump assembly oil:
Specifications).
If it is difficult to select gears, especially reverse gear, apply the interpretation of PR018 Hydraulic pressure.
Clear the computer fault memory.
Carry out the programming procedure for the Hydraulic unit - gearbox kit (without clutch) or Clutch or
gearbox + Clutch (see Replacement of components).
If the fault is still present, this means there is an internal mechanical fault with the gearbox, contact Techline.
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
Clear the computer memory.
Carry out a road test followed by another check with the diagnostic tool.

NOTESPriorities when dealing with a number of faults:
Apply the interpretation of other faults first.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present during a road test.
Special note:
Improper use of the gear lever when stationary may lead to this fault.
Using the diagnostic tool, via parameter PR018 Hydraulic pressure, check that the pump is activated at 40 bar
and stops at 50 bar.
Pressure level below a pressure threshold.
Fault linked to a lack of oil (internal or external leak) or to a pump failure.
Repair or replace if necessary (see MR 411 Mechanical, 21B, Sequential gearbox, Electric pump assembly
oil: Specifications).
Case of excessive pump operation:
–Internal or external leak in the circuit. For an external leak, locate the leak and repair if necessary. If there is an
internal leak, replace the hydraulic unit (see MR 411 Mechanical, 21B, Sequential gearbox,
Electrohydraulic unit: Removal - Refitting).
If the fault is still present, replace the accumulator (see MR 411 Mechanical, 21B, Sequential gearbox,
Pressure accumulator: Removal - Refitting).
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
Clear the computer memory.
Carry out a road test followed by another check with the diagnostic tool.

●Connection code 5HN,
●Connection code 5HX,
●Connection code 5AD,
between components 119 and 1059.
If the connection(s) are faulty and there is a repair method (see Technical Note 6015A, Repairing electrical
wiring, W iring: Precautions for repair), repair the wiring, otherwise replace it.
If the fault is still present, replace the oil pressure sensor on the Sequential gearbox (see MR 411, Sequential
gearbox, solenoid valve unit pressure sensor, Removal refitting).
AFTER REPAIRDeal with any faults detected by the diagnostic tool.

Check the level of oil in the discharged accumulator, refer to the interpretation of command AC081 Discharge
pressure accumulator.
Check the condition and position of the 30 A fuse for the pump in the engine compartment.
Use command AC012 “Hydraulic pump relay” with the diagnostic tool and check that the pump assembly is
working. If the pump is not working, perform the necessary repairs.
If the fault is still present, replace the oil pressure sensor (see MR 411, Sequential gearbox, solenoid valve unit
pressure sensor, Removal refitting).
Switch off the ignition.
Switch on the ignition again and carry out a new check using the diagnostic tool.
Replace the pump assembly if the fault reappears (see MR 411, Sequential gearbox, pump assembly,
Removal refitting).
AFTER REPAIRDeal with any faults detected by the diagnostic tool.
Clear the computer memory.
Carry out a road test followed by another check with the diagnostic tool.

STOREDHYDRAULIC PUMP
NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared as present if:
–The pump is switched off for 10 seconds.
–If the oil pressure is less than the starting value.
Special note:
–Fault warning light comes on.
Use the Wiring Diagrams Technical Note for New TWINGO.
Check for + AVC on connection BP36 of component 762.
If there is no + AVC, check fuse F1 30A on component 597.
If the fuse is correct, check the continuity of connection BP36 between components 762 and 597.
If the fuse is not correct, check the insulation to earth of connection BP36 between components 762 and 597.
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 connection and condition of the connectors of components 724, 119 and 762.
Also check the connection and condition of the 24-track intermediate connector located on the hydraulic unit.
If the connectors are faulty and if there is a repair method (see Technical Note 6015A, Repairing electrical
wiring, W iring: Precautions for repair), repair the connectors; otherwise, replace the wiring.
Check the continuity and insulation of the following connections:
●Connection code M between component 724 and earth MS-99E,
●Connection code 5AE between components 762 and 724,
●Connection code 5AF between components 119 and 762.
If the connection(s) are faulty and there is a repair method (see Technical Note 6015A, Repairing electrical
wiring, W iring: Precautions for repair), repair the wiring, otherwise replace it.
Case of excessive pump operation:
–Internal or external leak in the circuit. For an external leak, locate the leak and repair if necessary. If there is an
internal leak, replace the hydraulic unit (see MR 411, Sequential gearbox, Electro-hydraulic unit: Removal -
Refitting).
If the fault is still present, replace the accumulator (see MR 411, Sequential gearbox, Pressure accumulator:

NOTESSpecial notes:
Only consult this customer complaint after a complete check with the diagnostic tool.
If a gear was engaged when there is a request to start the engine check the oil level in the sequential gearbox
circuit.
Check the operation of the brake pedal switch as well as the condition of the gear lever switches (consult the
interpretation of statuses: ET043 “Lever switch no. 0”, ET044 “Lever switch no. 1”, ET045 “Lever switch
no. 2” and ET046 “Lever switch no. 3”).
Ensure that the cylinder and the clutch fork are operating correctly (damage, seizing, part breakage, etc.).
AFTER REPAIRClear the computer fault memory. Switch off the ignition and wait 20 seconds.
Carry out a road test followed by another check with the diagnostic tool.
