Description
Turbo hose, intake air resonator for Citroën and Peugeot vehicles with 1.6 HDi engine.
This intake resonator is a direct-fit replacement designed for 1.6 HDi turbo diesel applications. It helps restore correct intake tract geometry and reduce induction noise while preventing pressure fluctuations that can affect turbocharger response and engine idling. Commonly searched by part numbers 9657083280 and 144053, this component is suitable for professional workshops and experienced DIY mechanics who maintain Stellantis petrol and diesel platforms.
Technical Information
- Manufacturer: Stellantis
- Model: Citroën Berlingo; Citroën Xsara Picasso; Peugeot Partner (1.6 HDi)
- Product Codes: 9657083280, 144053
- Other Numbers: 9657083280, 144053
Function
The resonator dampens pressure pulsations and intake noise generated by the turbocharger and the engine’s airflow. By smoothing transient pressure waves it supports stable idle, quicker turbo response and reduces audible induction noise. It also contributes to correct airflow distribution in the intake tract.
Fitment And Compatible Models
Intended for Citroën and Peugeot models equipped with the 1.6 HDi turbo diesel engine. The most common applications include Citroën Berlingo, Citroën Xsara Picasso and Peugeot Partner. Always verify the part numbers stamped on the original component match the listed product codes for a direct fit.
Replacement Procedure
1. Park the vehicle on a level surface, allow the engine to cool and, if necessary, remove engine covers to access the intake tract. 2. Loosen clamps securing the resonator to adjacent hoses (hose clamps may be spring type or worm-drive). 3. Carefully disconnect any vacuum or breather lines attached to the resonator. 4. Remove the old resonator, inspect mating hoses and connections for damage or oil contamination. 5. Fit the new resonator ensuring correct orientation, replace clamps if worn, and tighten evenly to avoid deforming the hose. 6. Reconnect any removed lines and reassemble engine covers. 7. Start the engine and check for leaks, abnormal noises and correct idle. For best results perform a short test drive to confirm turbo response and lack of boost leaks.
Installation Recommendations
- Use new clamps if the originals are corroded or weakened; uneven or over-tightened clamps can damage the hose.
- Inspect adjacent intercooler and turbocharger connections for oil leaks or loose fittings — oil saturation shortens the hose life.
- Clean mating surfaces to ensure a tight seal and prevent air leaks.
- Avoid using excessive force when fitting plastic or soft rubber parts to prevent cracks.
- Perform a post-installation check for boost leaks and engine fault codes.
Most Common Causes Of Failure
Age-related rubber degradation and heat cycling are the primary causes. Oil contamination from a leaking turbocharger seal accelerates softening and swelling of the hose material. Mechanical damage from road debris or incorrect installation, and failed or loose clamps that allow movement and chafing, also lead to premature failure. When the resonator develops cracks or leaks, the result is reduced turbo efficiency, rough idle and potential engine warning lights related to air metering.
