NOTESOnly address this customer complaint after a complete check with the diagnostic tool.
Check the conformity of the mechanical components (see MR 411, Mechanical,
30A, General information, Brake, Specifications).
Vibration of the unit: check the presence and condition of the unit mounting insulating rubber mountings.
Vibration of pipes: check that all the pipes are securely clipped in their retaining clips and that there is no contact
between pipes or between pipes and bodywork.
To identify the source of the noise, use the control commands of the solenoid valves AC003 "Front left-hand
wheel solenoid valves", AC004 "Front right-hand wheel solenoid valves", AC005 "Rear left-hand wheel
solenoid valves" and AC006 "Rear left-hand wheel solenoid valves" and of the pump AC016 "Pump motor
test".

NOTESOnly address this customer complaint after a complete check with the diagnostic tool.
Check that the 4 vehicle tyres are identical and in accordance with the manufacturer's recommendations (see
MR 411, Mechanical, 35A, Wheels and tyres, Tyres, Identification).
Check that the pressures of the 4 tyres conform to the manufacturer's recommendations (see MR 411,
Mechanical, 35A, Wheels and tyres, Tyre pressure, Identification).
Using the diagnostic tool, check that the vehicle version corresponds to the vehicle type.
If necessary, reconfigure the vehicle version using command VP004 Vehicle parameters to correspond to the
vehicle type.
Using parameter PR030 Tachometric index, check that the tachometric index corresponds to the vehicle type.
If necessary, reconfigure the tachometric index using command VP007 Tachometric index to correspond to the
vehicle.
Check the connection and condition (possible wiring damage) of the connector of component 1175.
If the connector is faulty (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the connector, otherwise replace the wiring.
Check that component 1175 is properly mounted on the body and in the correct direction (the arrow must point
towards the front of the vehicle).
Calibrate component 583 using command VP003 Steering wheel angle sensor (see Configurations and
programming).
Clear the ESP sensor offsets using command RZ011 Sensor offsets.
Clear the faults from the computer using the command RZ001 "Fault memory".
Carry out a road test followed by another check with the diagnostic tool.
If the fault is still present:
–Adjust the axle geometry (see MR 411, Mechanical, 30A, General information, Front axle, Adjustment).
–Calibrate component 583 using command VP003 Steering wheel angle sensor (see Configurations and
programming).
–Clear the ESP sensor offsets using command RZ011 Sensor offsets.
–Clear the faults from the computer using the command RZ001 "Fault memory".
–Carry out a road test followed by another check with the diagnostic tool.
If the fault is still present, contact the Techline.
