Description
Air connection to the turbocharger for 2.0 HDI RH02 engines of Citroën and Peugeot vehicles.
This intake/turbo inlet pipe (OE references 9674900880 / 0382RN) is a direct-fit replacement designed for 2.0 HDI RH02 diesel engines. It restores correct turbocharger air routing, helps maintain boost pressure and engine responsiveness, and is suitable for professional workshops and experienced DIY mechanics who service Citroën and Peugeot models. Manufactured to match the original shape and connection points, the pipe ensures secure sealing to the turbocharger and intercooler system, reducing the risk of boost leaks and drivability faults.
Technical Information
- Manufacturer: Stellantis (Citroën / Peugeot)
- Model: 2.0 HDI RH02
- Product Codes: 9674900880, 0382RN
- Other Numbers: RH02 (Engine Code)
Compatibility
Commonly fitted to the following models (check engine type RH02): Citroën C4 Picasso, Citroën C5 X7, Citroën C8, Peugeot 3008 I, Peugeot 5008 I, Peugeot 807. Also compatible with other Stellantis vehicles equipped with the 2.0 HDI RH02 engine that use the same turbo inlet geometry.
Function And Typical Faults
The turbo inlet pipe directs compressed air from the turbocharger into the intercooler or intake tract. A correctly functioning pipe is essential for maintaining boost pressure, engine power and fuel efficiency. Typical failure modes include cracks or splits in the rubber/composite material, deterioration at clamp connection points, and deformation caused by prolonged heat cycles or contact with engine oil. Common symptoms of a failing turbo inlet pipe are loss of boost, reduced acceleration, surging or hesitation under load, and sometimes a check engine light related to boost or airflow faults.
Replacement Interval And Causes Of Failure
There is no fixed mileage for replacement; the part commonly fails on higher-mileage cars or vehicles exposed to frequent heat cycling, oil contamination, or mechanical stress from loose clamps. Road salt, engine bay corrosion and prior incorrect installation can accelerate wear. Inspect the pipe during routine turbo or intercooler service and replace at the first sign of cracks, soft spots or oil saturation.
Installation Recommendations
- Park the vehicle on a level surface, allow the engine to cool and, as a safety precaution, isolate the battery if you will be working near electrical components.
- Loosen and remove the clamps securing the pipe to the turbocharger outlet and the intercooler or intake flange. Retain or replace clamps with high-quality worm-drive or T-bolt clamps as appropriate.
- Carefully disconnect any attached sensors, vacuum lines or brackets before removing the old pipe to avoid damage.
- Fit the replacement pipe, ensuring correct orientation and full seating on mating flanges. Use new clamps or torque existing clamps evenly to ensure a tight seal—avoid over-tightening plastic fittings.
- After installation, start the engine and check for boost leaks at idle and under light load. Perform a short road test to confirm restored boost response and normal engine operation.
Workshop Tips
- Always inspect adjacent components (turbocharger outlet, intercooler hoses, clamps and vacuum lines) for damage or contamination when replacing the inlet pipe.
- If oil contamination is present inside the pipe, investigate turbo oil seals and crankcase ventilation system for faults.
- Replace worn or corroded clamps with stainless steel T-bolt clamps for a more reliable long-term seal.
Why Choose This Part
Using the correct intake/turbo inlet pipe with the OEM part references ensures proper fitment and reliable boost control. This helps maintain engine performance and prevents common drivability issues caused by boost leaks. Intended for professional mechanics and knowledgeable DIYers who require an accurate, ready-to-fit replacement for 2.0 HDI RH02 applications.
