Description
Assembled Delphi air metering valve for Citroën Xsara Picasso 1.6 HDi 80 kW vehicles.
High-quality Delphi air metering valve designed for the 1.6 HDi engine in the Citroën Xsara Picasso. This intake flap / throttle actuator controls the amount of bypass air and fine-tunes idle and transient response on turbocharged HDi engines. The part is commonly searched by product numbers 9655971680 and 0345C0, so it is ideal for workshops and DIY mechanics looking for a direct-fit replacement that restores smooth idle and drivability.
Technical Information
- Manufacturer: Delphi
- Model: Citroën Xsara Picasso 1.6 HDi (80 kW)
- Product Codes: 9655971680, 0345C0
- Other Numbers: NFP
Function And Benefits
The air metering valve modulates intake airflow for idle speed control and transient load compensation. On 1.6 HDi engines it helps maintain stable idle, supports smooth deceleration, and reduces engine stalling during low-load conditions. Replacing a faulty valve restores correct air metering, reduces rough idle and hesitation, and can eliminate fault codes related to idle control.
Compatibility And Application
Engineered for Citroën Xsara Picasso with the 1.6 HDi 80 kW engine. Often referenced in searches and service manuals by the part numbers listed above. Suitable for technicians and experienced DIYers replacing the intake flap/air metering component on compatible Stellantis diesel models using the same intake assembly.
Installation Recommendations
- Preparation: Park on a level surface, allow the engine to cool and disconnect the negative battery terminal before starting work.
- Removal: Remove the intake hose and any obstructing components, unplug the electrical connector, and unbolt the valve from the intake manifold. Inspect the gasket and mating surface for damage.
- Fitment: Fit the new valve with a new gasket if available, secure mounting screws, reconnect the electrical connector and intake piping. Ensure all clamps are tight and there are no vacuum or air leaks.
- Post-Installation: Start the engine and check idle stability. Clear stored faults with a diagnostic tool if required and verify no new fault codes appear.
Why The Part Most Commonly Fails
Common failure causes include carbon and soot buildup in the intake path, worn or seized actuator components, degraded electrical connector contacts, and damage to plastic gears or internal mechanisms. Aggressive driving, long intervals between air/filter maintenance, and prolonged low-speed operation with heavy soot generation accelerate wear. Symptoms of failure typically include unstable idle, stalling, fluctuating RPM, and related engine fault codes.
Practical Tips For Mechanics
- Inspect and clean the intake tract and EGR system when replacing the valve to prevent rapid re-contamination.
- Replace the sealing gasket to ensure airtight fitment and prevent vacuum leaks.
- Check wiring harness and connector pins for corrosion or damage; poor electrical contact is a frequent cause of intermittent faults.
- Keep the old unit for comparison of mounting orientation and connector position before finalizing installation.
Ready-to-fit air metering valve with clear product codes for quick identification in catalogs and ordering systems—an efficient choice for workshops and experienced DIYers who need a reliable replacement for Citroën Xsara Picasso 1.6 HDi 80 kW models.
