Description
Assembled Delphi air metering unit for Citroën and Peugeot vehicles with 1.6 HDi engines. Throttle Valve, Intake Flap.
This Delphi assembled throttle body is a direct-fit replacement for many 1.6 HDi (DV6) engines found in Citroën and Peugeot compact vans and MPVs. Designed to regulate the intake airflow precisely, the unit controls engine idle, transient response and works together with the engine control unit to ensure smooth fueling and emissions control. Supplied part numbers 9660030580 and 0345E7 match common OEM references used on a range of PSA/Stellantis models.
Benefits And Applications
Ideal for mechanics and DIY enthusiasts who need a cost-effective repair option, this throttle body delivers reliable airflow control when the original unit has failed or developed faults. Typical improvements after replacement include restored idle stability, quicker throttle response, elimination of rough idling or stalling, and reduced limp-home mode occurrences. The part is particularly suited for vehicles with the 1.6 HDi engine platform.

Symptoms Of A Faulty Throttle Body
- Unstable or high idle, Idle surging
- Poor throttle response or Hesitation on acceleration
- Engine Stalling At Low Speed Or Idle
- Engine Management Light Or Limp Mode Activation
How The Part Is Replaced
Replacement is straightforward for a skilled technician or competent DIYer with basic tools. Typical procedure:
- Disconnect The Battery Before Starting To Avoid Short Circuits And Protect Engine Electronics.
- Remove Engine Cover And Air Intake Hose Leading To The Throttle Body.
- Unplug The Electrical Connector And Any Vacuum Lines Or Sensors Attached.
- Remove Mounting Bolts, Extract The Old Throttle Body And Replace The Gasket/O‑Ring If Present.
- Fit The Replacement Unit, Reinstall Bolts To Specified Torque, Reconnect Electrical And Vacuum Lines.
- Reconnect Battery And Perform Throttle Adaptation/Idle Relearn If Required (See Recommendations).
Mounting Recommendation
Always Use Correct Torque Values For Fasteners And Replace Any Seals Or Gaskets To Prevent Air Leaks. After Installation, Clear Any Stored Fault Codes And Carry Out Throttle Adaptation Or Idle Relearn Using A Diagnostic Tool If The Engine Does Not Settle To Normal Idle. If You Are Uncertain About Calibration Steps, Have The Final Setup Performed By A Technician With PSA-Compatible Diagnostic Equipment.
Why This Part Most Often Fails
Throttle bodies on 1.6 HDi engines commonly fail due to carbon and soot buildup from EGR flow and intake deposits, which restricts the valve movement and interferes with position sensors. Wear Of The Internal Potentiometer/Throttle Motor Or Contamination Of The Actuator Can Also Cause Erratic Signals To The Engine Control Unit. Electrical Connectors And Wiring Damage From Heat Or Corrosion May Contribute To Intermittent Faults.
Additional Notes
This is a used/previously fitted Delphi assembled unit intended as a replacement part. It is supplied with the listed product codes; always inspect the part and mating surfaces during fitment and follow vehicle manufacturer safety instructions.
