Description
Intake resonator for Citroën and Peugeot vehicles with 1.6 HDi engine.
This intake air resonator is designed for Citroën and Peugeot models equipped with the 1.6 HDi diesel engine. It reduces intake noise, evens out airflow in the intake tract and helps maintain smooth turbo response and consistent engine behavior under varying loads. Commonly referenced by part numbers 9654718080 and 144053, this resonator is a direct-fit replacement for worn or damaged original components and is aimed at professional technicians and experienced DIY mechanics working on Berlingo, Xsara Picasso and Partner models.
Benefits
Replacing a damaged resonator restores quiet operation of the intake system, reduces unwanted drone and turbulence, and prevents unmetered air leaks that can affect turbo efficiency and combustion stability. Correct fitment also ensures proper sealing of the intake path and reduces the risk of contaminant ingress.
Technical Information
- Manufacturer: Stellantis / Citroën / Peugeot
- Model: Citroën Berlingo, Citroën Xsara Picasso, Peugeot Partner (with 1.6 HDi engine)
- Product Codes: 9654718080, 144053
- Additional Numbers: 144053, 9654718080
Fitment And Location
The resonator is mounted in the intake tract, typically between the air filter housing and the turbocharger/intercooler or throttle body depending on the vehicle layout. Exact position can vary by model year and engine variant; it is a bolt- or clamp-attached component integrated into the intake piping.
Replacement Procedure (Overview)
- Allow the engine to cool and work in a clean environment to avoid debris ingress.
- Loosen the hose clamps securing the intake pipes and disconnect any attached sensors or vacuum lines (note their routing for reassembly).
- Remove the retaining clips or bolts and extract the old resonator from the intake tract.
- Inspect mating pipes, seals and clamps; replace damaged seals and worn clamps to ensure a proper airtight joint.
- Install the new resonator in the correct orientation, secure clamps/fasteners to manufacturer torque recommendations, and reconnect sensors and hoses.
- Start the engine and check for leaks, abnormal noises or loose fittings. Re-check clamps after a short test drive.
Installation Recommendations
Use quality worm-drive or T-bolt clamps and replace any perished rubber seals. Clean the mating surfaces and inspect adjacent intake hoses for cracks or oil contamination—replacing compromised hoses at the same time prevents recurring issues. For safety and best results, perform the replacement on a cool engine and follow manufacturer service procedures for disassembly and reassembly.
Why This Part Commonly Fails
Resonators typically fail due to age-related deterioration (rubber hardening and cracking), heat and vibration exposure, impact or contact with road debris, and oil contamination from crankcase breather systems. Loose or broken clamps can also allow the part to shift and develop leaks. Symptoms of failure include increased intake noise (whistle, drone), rough idle or inconsistent turbo response caused by unmetered air entry or disrupted airflow.
