Commonly searched under part numbers 9655971680 and 0345C0, this unit is a practical option when the original air dosing/throttle flap assembly malfunctions or causes unstable idle and emission issues.
Technical Information
- Manufacturer: Delphi
- Model: Citroën Xsara Picasso 1.6 HDi 80 kW
- Product Codes: 9655971680, 0345C0
- Additional Numbers: NFP
Compatibility
Designed for Citroën Xsara Picasso with the 1.6 HDi 80 kW engine. Frequently referenced by the OEM/PSA part numbers above. Check the physical shape, electrical connector and mounting points to confirm fitment when fitting to other variants.
Function
The air metering unit (air dosing/throttle flap assembly) regulates bypass airflow and intake metering for stable cold and idle running on HDi diesel engines. Controlled by the engine management system, it ensures correct air quantity for starting, idling stability and emissions control.
Replacement Procedure
- Disconnect the battery before starting work to avoid electrical damage and fault codes.
- Remove the intake ducting to gain access to the metering unit and unplug the electrical connector.
- Unscrew the mounting fasteners and carefully extract the unit, observing any seals or gaskets.
- Install the new unit, replace any damaged seals, tighten fasteners evenly, reconnect the electrical connector and reassemble intake ducts.
- After installation clear any related fault codes and perform idle relearn/adaptation if required by the engine ECU.
Installation Recommendations
- Always disconnect the battery before removal and follow manufacturer instructions to prevent damage.
- Inspect and, if necessary, replace intake hoses, clamps and sealing gaskets to avoid air leaks that can affect operation.
- Use proper diagnostic tools to clear fault codes and to run any required idle adaptation procedures after fitting.
- Work In A Clean Environment To Prevent Dirt Entering The Intake During Replacement.
Why The Part Most Frequently Fails
Failures are usually caused by carbon buildup and deposits that cause the flap or actuator to stick, electrical wear of the motor or position sensor, connector corrosion or wiring faults, and vacuum/air leaks in the intake tract. Symptoms include rough or unstable idle, difficulty starting, increased emissions and fault codes related to idle control.
Who Should Fit This Part
Suitable for experienced DIY mechanics and professional workshops. If you are not equipped with diagnostic tools for code clearing and idle adaptation, consider professional installation to ensure correct commissioning and engine behaviour.
