The 2.0 HDI throttle valve for RHR 100 kW engines is an important part of the intake that regulates the amount of air entering the engine. A properly functioning throttle ensures smooth engine operation, better throttle response and optimal fuel consumption. A faulty flapper is often accompanied by a fluctuating idle speed, loss of power, engine stall, or an illuminated check engine light.

This part is intended for Citroën and Peugeot cars with a 2.0 HDI diesel engine (RHR 100 kW) and is suitable as a replacement for an original part with matching numbers.

This part is suitable for customers looking for a specific throttle by part number. If the code matches (e.g. 9657522480, 0345F0 or 0345E9), it is a targeted and reliable replacement of the original part.

Installation recommendations:
– Visually check the condition of the sealing surfaces and connectors before assembly.
– Always use a quality seal, or new O-rings according to the suction design.
– Fit the damper evenly, tighten the screws crosswise and with the prescribed torque to avoid deformation of the body.
– Before connecting the electrical connector, check the cleanliness of the contacts and their firm engagement.
– After installation, we recommend cleaning the surrounding part of the intake (if it is clogged with oil and soot) and performing a basic throttle adjustment / adaptation using diagnostics, if the car requires it.
– After the first start, let the engine idle for a short time and check the intake for leaks and any error codes in the control unit.

A correctly selected and installed throttle valve will help restore a stable idle, better engine response to gas and overall quieter operation of the 2.0 HDI diesel engine.

This direct-fit throttle body is designed for the 2.0 HDi RHR 100 kW powerplants used across several Citroën and Peugeot models. Supplied with original Stellantis references, it is a common replacement part searched by part numbers (e.g. 9684269380, 0345F0, 0345E9) and is aimed at professional mechanics and experienced DIY technicians who need a reliable intake control component.

Overview

The throttle valve (throttle body) controls air admission to the engine and supports idle regulation, EGR control and functions related to emission management on modern common‑rail diesel engines. On 2.0 HDi RHR units it ensures correct airflow signals to the engine control unit for smooth idle, proper load response and stable regeneration cycles for aftertreatment systems.

Installation Recommendations

• Disconnect the battery before starting work and follow the vehicle manufacturer’s safety procedures.
• Remove the intake ducting to access the throttle body, unplug the electrical connector and remove the mounting bolts.
• Replace the throttle body gasket/seal when fitting the new unit to prevent vacuum leaks and intake contamination.
• After fitting, clean surrounding intake passages from carbon and debris to avoid premature contamination of the new part.
• Perform throttle adaptation/relearn following the manufacturer’s procedure. If a dedicated PSA diagnostic tool (DiagBox/Lexia) is available, use it to confirm correct calibration and fault code clearance. If not available, follow the prescribed idle/relearn routine in the service manual.
• Always tighten fasteners to factory torque specifications and inspect electrical connections for corrosion or damage.

Why This Part Commonly Fails

• Carbon and soot buildup on the throttle plate and bore, causing sticking or incorrect air readings.
• Faulty or drifting throttle position sensor (TPS) or internal potentiometer wear.
• Contamination from oil vapors or EGR deposits leading to mechanical jamming.
• Vacuum leaks or damaged gaskets that alter airflow and cause unstable idle or warning lights.
• Electrical connector corrosion or broken wiring causing intermittent signals to the ECU.
