Description
Air intake pipe – turbo intake for Citroën Peugeot 2.0 HDi RHR engines. Air connection at the turbocharger.
This replacement intake pipe is designed for the 2.0 HDi RHR Diesel engines used across several Citroën and Peugeot models. It provides a secure air route from the turbocharger outlet toward the intercooler/intake system, restoring correct boost delivery and engine response. Commonly searched by part numbers 9649466180 and 0382AR, this pipe is ideal for professional workshops and experienced DIY mechanics looking for a direct-fit component that maintains proper turbocharger connection and airflow.
Technical Information
- Manufacturer: Stellantis (Citroën / Peugeot)
- Model: 2.0 HDi (Engine Code RHR)
- Product Codes: 9649466180, 0382AR
- Additional Numbers: RHR (Engine Code)
Fitment
Typical compatible models include Citroën C5 (including X7), Citroën C8 and Peugeot 307, 407, 807 with the 2.0 HDi RHR engine. Always verify engine code RHR when selecting parts to ensure correct fitment.
How To Replace
- Park on level ground, apply the handbrake and allow the engine to cool.
- Locate the turbocharger outlet pipe and trace the intake pipe to the intercooler/intake manifold connections.
- Loosen hose clamps securing the pipe at both ends. Remove any retaining brackets or clips if present.
- Carefully withdraw the old pipe, taking note of any sealing rings or gaskets to be replaced.
- Inspect mating surfaces, clamps and seals for damage or oil contamination. Clean before fitting the new pipe.
- Install the new pipe, replace old clamps and seals as required, and tighten clamps to a snug fit. Avoid over-tightening which can crush flexible sections.
- Start the engine and check for boost leaks, unusual noises or engine warning lights. Road-test under light load and recheck fasteners.
Installation Recommendations
- Replace hose clamps and any worn O-rings or seals when fitting the new pipe to ensure an airtight connection.
- Inspect adjacent components (intercooler, turbocharger outlet, clamps) for oil deposits or damage — oil ingress often indicates turbo shaft seal wear.
- Use appropriate tools and avoid sharp bends or kinks in flexible sections during installation.
- After installation, verify boost pressure and listen for hissing or whistling that indicates leaks.
- For professional fitment, a smoke test or boost test can confirm the integrity of the intake system.
Why This Part Most Often Fails
- Ageing And Heat Cycling: Repeated heating and cooling of rubber or hybrid hoses cause hardening, cracking and eventual air leaks.
- Oil Contamination: Turbocharger oil leaks or blow-by can degrade hose material and seals, accelerating failure.
- Mechanical Damage: Poorly routed pipes, overtightened clamps or contact with hot components can cause abrasion or perforation.
- Faulty Clamps Or Connections: Loose or corroded clamps allow the pipe to slip or leak under boost.
- Symptoms Of Failure: Loss Of Power, Hissing/Whistling Noises, Poor Throttle Response And Possible Turbo Underboost Faults.
This intake pipe is a practical, cost-effective part to restore correct turbocharger airflow on affected Citroën and Peugeot 2.0 HDi RHR engines. Because many customers search by part number, the OE references 9649466180 and 0382AR are included to help you find the correct replacement quickly.
