Description
High-quality Bosch metering flap designed for PSA 2.0 and 2.2 HDi engines. This component controls the amount of fuel delivered in diesel HDi systems and is commonly identified by OEM numbers 9638246280, 0928400430 and 0345A3. The part is widely used across Citroën and Peugeot vehicles running 2.0/2.2 HDi engines and is often searched for by its product codes.
Function And Benefits
The metering flap precisely regulates fuel metering, helping to maintain stable idling, consistent engine response and optimal fuel consumption. Proper operation is essential for combustion control and overall drivability. Replacing a worn or faulty flap restores correct fuel delivery and can eliminate symptoms caused by mis-metering.
Common Symptoms Of Failure
- Rough or unstable idle and irregular engine running
- Loss of power or hesitation under load
- Increased fuel consumption
- Illumination of engine warning lamp or related fault codes
Causes Of Wear And Typical Lifetime
Failures usually result from mechanical wear, contamination (carbon or particulate build-up), or electrical/actuator faults. Lifespan depends on driving conditions and maintenance; failures can occur after prolonged service (commonly noticeable after high mileage), but timing varies by vehicle and service history.
Replacement And Installation Notes
Intended for fitment by qualified technicians or experienced DIYers. General replacement steps: disconnect the battery, relieve fuel system pressure if required by the specific vehicle procedure, gain access to the metering flap location (consult a vehicle-specific repair manual), disconnect electrical connectors, remove mounting fasteners, replace any sealing gaskets or O-rings, install the new unit and reconnect electricals. After fitment, clear fault codes and perform any required adaptation or relearn procedures as per manufacturer instructions.
