Magneti Marelli throttle body housing designed as a direct-fit replacement for selected Citroën and Peugeot models with 2.2 16V engines. This component restores correct air intake regulation, helping to eliminate rough idle, loss of power and erratic throttle response. The part is frequently searched and ordered by its product code 163615, so it is ideal for workshop technicians and experienced DIYers who prefer to identify parts by reference number.

Technical Information

• Manufacturer: Magneti Marelli
• Model: Citroën C8; Peugeot 406, 407, 607, 807 (2.2 16V Engines)
• Product Codes: 163615
• Additional Numbers: 163615 NFP

Function And Symptoms

The throttle body controls the volume of air entering the engine by regulating the throttle plate opening. It works together with the engine management system to ensure correct air–fuel mixture across all engine loads. Common symptoms of a faulty or contaminated throttle body include unstable or high idle, hesitation under acceleration, reduced engine power, stalling at low revs and illumination of the engine management lamp.

Common Failure Causes

• Carbon and oil buildup on the throttle plate and bore causing sticking or improper sealing.
• Wear or failure of the throttle position sensor or actuator motor (electronic throttles).
• Vacuum leaks or intake tract leaks affecting airflow measurements.
• Electrical connection corrosion or wiring damage leading to intermittent signals.

How Often It Fails

Service life varies with driving conditions and maintenance. Throttle bodies can last well beyond 100,000 km in well-maintained vehicles, but heavy urban driving, frequent short trips and lack of intake service accelerate carbon buildup. Inspect during major service intervals and consider cleaning or replacement if symptoms appear.

Replacement And Installation Guide

High-level replacement steps for qualified personnel or experienced DIY mechanics:

• Ensure Safety: Disconnect the battery before starting work to avoid short circuits and prevent unintended throttle operation.
• Access: Remove the intake ducting and airbox components to access the throttle body.
• Disconnect: Unplug the electrical connector(s) and any vacuum hoses attached to the unit. Label connectors if needed.
• Remove: Unscrew the mounting bolts and remove the throttle body. Replace the gasket if applicable.
• Install: Fit the new throttle body, tighten bolts to the manufacturer’s specified torque, reconnect hoses and connectors, and reassemble the intake components.
• Relearn/Adaptation: Perform throttle adaptation/relearn procedure using a diagnostic tool where possible; otherwise follow the vehicle manufacturer’s prescribed ignition/cycle routine to allow the ECU to recalibrate idle and throttle response.

Installation Recommendations

• Always Replace Gaskets: Fit a new intake/throttle gasket to ensure an airtight seal.
• Use Proper Tools: Use correct fastener torques and avoid overtightening to prevent damage to the housing.
• Clean Surroundings: Clean the mating surfaces and intake tract to minimize contamination entering the engine.
• Diagnostic Check: After installation, run a diagnostic scan to clear any stored fault codes and confirm proper sensor signals and adaptation status.

Throttle valve 2.0 HDI Peugeot 9646846380 0345F0 is an original part intended for diesel engines 2.0 HDI, typically with the designation RHR with an output of 100 kW. It is a complete throttle body with an intake throat, which ensures the correct regulation of the amount of air taken into the engine and contributes to smooth operation, power and refined running at idle and when coasting after the engine is turned off.

This part is especially suitable for Citroën and Peugeot cars with a 2.0 HDI engine, popular with car mechanics and DIYers who service their cars themselves. It is often searched for by product numbers, so here is an overview of the identification:

Manufacturer: PSA Citroën Peugeot
Model: 2.0 HDI RHR 100 kW (selected Citroën and Peugeot models)
Product codes: 9646846380, 0345F0, 0345E9
Other numbers: may vary depending on the specific manufacturer of the sub-group (e.g. different OEM sub-variants), but PSA numbers 9646846380 / 0345F0 / 0345E9 are important

The throttle valve in these engines plays an important role in regulating the air flow to the intake, cooperates with the EGR system and has an effect on smoke, consumption and engine operation. Erratic idle, jerking, hibernation, or intake control error codes often occur with a faulty throttle.

Thanks to a properly functioning throttle, the 2.0 HDI engine can achieve optimal performance and lower consumption, which is essential both for everyday operation and for reliability on long journeys. A used original part from a car of the same concept is in most cases a better choice than cheap non-original replacements, which may have a shorter service life or worse tightness and accuracy of regulation.

Installation recommendations:
Before installation, check the sealing surfaces of the valve and the intake and replace the seals if necessary. When replacing, carefully clean the area around the intake so that dirt does not enter the engine. Connect the electrical connector only after the damper is completely seated in the intake, tighten the screws evenly according to the engine manufacturer’s recommended tightening torque. After assembly, it is advisable to carry out the basic adjustment and adaptation of the damper using diagnostics, possibly delete the saved error codes and carry out a test drive to check the correct function.

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.
