Description
Air Connector At The Intercooler For Citroën And Peugeot Vehicles With 2.0 HDI RH02 Engine.
Product Overview
This air connector (intake coupling) is designed for the intercooler circuit on Citroën and Peugeot models equipped with the 2.0 HDi RH02 diesel engine. It provides a secure, leak-free connection between intercooler piping and turbocharger/intake components, ensuring stable boost pressure and optimal engine performance. Commonly searched under the product code 0382NE, this part is intended for professional workshops and DIY mechanics who require a reliable replacement for worn or damaged intake connections.
Technical Information
- Manufacturer: Stellantis
- Model: Citroën C4 Picasso; Citroën C5 X7; Peugeot 3008 I; Peugeot 5008 I
- Product Codes: 0382NE
- Other Numbers: RH02 (Engine Code), 2.0 HDi
Function And Importance
The connector seals the airflow path between the turbocharger/intercooler and the intake manifold or downstream piping. It must withstand pressure pulses, heat cycles and vibration. A tight, undamaged connection preserves turbo boost efficiency, prevents air leaks that would cause loss of power, rough running or increased fuel consumption, and keeps intake sensors (MAF/pressure) readings stable.
Fitment And Replacement
Replacement is straightforward for a trained technician: warm the engine to operating temperature then allow it to cool slightly (work on a warm, not hot, engine) so seals remain pliable. Remove clamps or fasteners securing the old connector, detach any sensor harnesses or brackets interfering with access, slide off the damaged connector and clean the mating surfaces on the intercooler and pipe. Fit the new connector in the correct orientation, secure with new or inspected clamps and ensure a uniform, tight seal. After installation, check for boost leaks with a pressure test or by road test under load.
Common Failure Causes
- Abrasion and Ageing: Rubber and silicone materials harden, crack or develop splits after years of heat and oil exposure.
- Oil Contamination: Turbocharged engines can route oil vapour into the intake system; oily deposits accelerate material degradation.
- Overpressure Events: Faulty wastegate or turbo faults can create pressure spikes that rupture connectors or cause hose blow-offs.
- Improper Clamping: Loose or uneven clamps allow movement and lead to chafing or leaks.
Installation Recommendations
- Inspect Mating Surfaces: Clean intercooler and pipe ends of oil, dirt and corrosion before fitting.
- Replace Clamps: Use quality, correctly sized clamps and tighten evenly to manufacturer torque where specified.
- Check For Oil Sources: If connector failure is due to oil contamination, inspect turbocharger seals and crankcase ventilation system.
- Pressure Test After Fitment: Verify there are no boost leaks by performing a static pressure check or road test under load.
- Work Safely: Perform work with the engine off and cooled sufficiently. Wear appropriate PPE and follow workshop safety procedures.
Why Replace This Part
Failing connectors cause reduced engine performance, turbo lag, diagnostic fault codes and sometimes visible smoke or oil residue in the intake. Replacing a worn or cracked air connector restores reliable boost delivery and helps prevent secondary damage to the turbo system and sensors.
Compatibility Note
