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.

Why This Part Is Often Searched By Number

Technicians and DIY customers commonly search by the product code 163615 to ensure exact fitment and fast identification. Using the part number reduces the risk of ordering incorrect variants and speeds up procurement for repairs.

Why The Part Most Commonly Fails

The most frequent cause of throttle body failure is carbon contamination that prevents the throttle plate from closing or opening smoothly, leading to poor running and check engine faults. Electronic failures such as a faulty position sensor or actuator motor and electrical connector issues are also common failure modes.

For professional installation, follow the vehicle manufacturer’s service manual procedures and safety guidelines. Order by product code 163615 for a quick match to the models listed above.

Reason For Failure

Common causes of throttle body malfunction include carbon and soot buildup that restricts flap movement, wear or failure of the throttle position sensor or electronic actuator, contaminated intake air, vacuum leaks at the gasket or hoses, and electrical connector corrosion. Symptoms typically include unstable idle, poor throttle response, limp-home mode, and engine management fault codes. Regular inspection and cleaning of the intake and throttle body area can delay failure, but sensor or actuator faults require replacement.

How To Replace

Replacement is straightforward for technicians familiar with intake systems: remove air intake components, disconnect electrical and vacuum connections, unbolt the throttle body, install the new unit with a new gasket, reconnect hoses and connectors, and perform the required throttle adaptation. If diagnostic faults persist after replacement, check wiring, connectors and related engine management sensors.

Notes For Professionals And DIYers

• Part is intended for the listed engine types and vehicle models—confirm fitment by matching product codes with vehicle documentation before installation.

Function And Common Faults

The throttle body controls the amount of air entering the engine by means of a butterfly plate and associated position sensing. On modern petrol engines the assembly typically contains the throttle plate, a position sensor (TPS) and an actuator or idle control interface. Common symptoms of a failing throttle body include unstable idle, reduced throttle response, engine warning light illumination and fault codes related to throttle position or idle control.

Why Throttle Bodies Fail

Most failures are caused by carbon and oil deposits building up on the throttle plate and bore, which restrict movement and corrupt position readings. Electrical faults in the position sensor or actuator can also occur over time due to moisture, wear or intermittent contacts. Vacuum leaks at the mounting flange or a damaged gasket further upset idle control and engine performance.

Installation Recommendations

Before starting, always disconnect the battery and follow the vehicle manufacturer’s safety guidelines. Typical replacement steps:

• Remove the air intake hose and intake resonator to access the throttle body.
• Disconnect the electrical connector and any vacuum lines attached to the body.
• Unbolt the throttle body from the intake manifold, remove old gasket and clean mating surfaces.
• Fit the new throttle body with a correct gasket, torque bolts to manufacturer specs, reconnect electrical connector and vacuum lines.
• Reconnect the battery and perform throttle adaptation / idle relearn procedure according to the vehicle service manual or using a diagnostic tool.

Professional tools are recommended for proper relearn/initialization to ensure correct idle and throttle response. Replace any damaged hoses or gaskets during installation to prevent future issues.

Replacement Tips For Mechanics And Enthusiasts

Inspect the intake tract and PCV system for oil contamination when installing a new throttle body. If heavy carbon buildup is present, consider cleaning the intake and replacing the intake gasket. Where possible, check for stored diagnostic trouble codes before and after replacement to confirm fault resolution.
