Description
Overview
This Intake Throttle Valve is a Delphi-design replacement part for PSA 1.6 HDi engines fitted to Citroën and Peugeot models. Supplied under reference numbers 9649832580 and 0345C1, it controls intake airflow for idle stability and assists exhaust gas recirculation management on modern diesel engines. The unit is aimed at professional workshops and competent DIY mechanics who often search by part number for fast, accurate fitment.
Key Benefits
- Direct-fit replacement for many 1.6 HDi applications using OEM reference numbers 9649832580 / 0345C1.
- Restores proper idle control and helps maintain correct EGR operation.
- Quality Delphi construction designed for reliable electrical and mechanical operation.
- Useful for rapid identification by part number in workshop ordering systems.
Compatibility
Commonly fitted to PSA DV6 1.6 HDi diesel engines found in various Citroën and Peugeot models, including but not limited to: Peugeot 207, 307, 308, 3008, Partner; Citroën C3, C4, Berlingo. Always verify fitment using the part numbers 9649832580 or 0345C1 against the vehicle chassis or parts catalog before purchase.
Function And Typical Failure Modes
The throttle valve (throttle body) regulates intake airflow and provides the engine management system with a controlled restriction used for idle control and to support EGR function on diesel engines. Common causes of malfunction include carbon and soot buildup on the plate and bore, electrical failures in the actuator or position sensor, and mechanical wear. Symptoms of a failing unit can include unstable idle, rough starting, reduced drivability, or diagnostic fault codes related to throttle position or idle control.
Replacement & Installation Notes
Basic replacement steps for a competent technician or DIY mechanic:
- Disconnect the negative battery terminal before work to avoid electrical damage.
- Remove the intake ducting and any sensors or vacuum lines obstructing access to the throttle body.
- Unplug the electrical connector and remove mounting fasteners, then install the new unit in reverse order.
- Inspect and replace the throttle body gasket if required and ensure all vacuum/boost hoses are correctly reattached.
- After installation it is often necessary to perform throttle adaptation or an ECU relearn procedure using a diagnostic tool to restore correct idle and driveability.
Service Life
Service life depends on driving conditions and maintenance. Soot-prone urban driving and long intervals between intake cleaning can accelerate carbon buildup. Many units remain serviceable beyond 100,000 km, but symptoms or electrical faults typically indicate replacement is required.
