Air Connection For Citroën Peugeot 2.0 HDi RH02 Engines
Product Overview
This air connection (intake connector) is designed for 2.0 HDi RH02 engines used in a range of Citroën and Peugeot models. It ensures secure routing of intake air between components such as the airbox, turbocharger and intercooler depending on the vehicle configuration. Commonly referenced by part code 0382NH (0382.NH), this element is an easy-to-search replacement part for workshops and DIY mechanics.

Function and Benefits
The intake connector guides and seals the airflow in the induction system. A correct, undamaged connector prevents unmetered air leaks that can cause rough idling, loss of boost, excessive smoke or incorrect air/fuel mixture readings. Replacing a worn or damaged connector restores proper boost response, improves engine behavior and prevents diagnostic trouble codes related to intake leaks.
How To Replace
Replacement is straightforward for a trained mechanic or competent DIYer. General steps:
- Park the vehicle on a level surface and allow the engine to cool.
- Locate the faulty connector in the intake tract (between airbox, turbo and/or intercooler depending on model).
- Loosen hose clamps and remove any retaining clips or sensor plugs that obstruct removal. Mark or note routing of vacuum lines if present.
- Remove the old connector, inspect mating pipes and clamps for damage or corrosion.
- Fit the new connector in the correct orientation, replace clamps with quality clamps and tighten to a firm but not over-torqued setting.
- Reconnect any sensors, vacuum lines or clips and start the engine to check for leaks and correct operation.
Tip: Replace worn clamps and inspect adjacent components (intercooler pipes, turbo couplings, MAF sensor boot) during the job to avoid repeat failures.
Installation Advice
Use correct-size clamps and ensure sealing faces are clean. Avoid over-tightening stainless worm-gear clamps on softer hose materials—use constant-tension or Oetiker-style clamps where appropriate. After installation, perform a visual check under load (rev the engine) or a smoke/leak test to confirm the repair.
Why This Part Commonly Fails
Typical failure causes:
- Age-related hardening and cracking of the rubber or silicone material.
- Exposure to engine heat and oil contamination leading to softening, swell or embrittlement.
- Mechanical fatigue from vibration and movement, or damage during previous repairs.
- Corroded or loose clamps allowing the connector to slip and develop leaks.
Failures manifest as boost loss, check engine lamp, rough idle or reduced engine performance.
Search And Identification
This part is often sought by its product codes 0382NH or 0382.NH. When ordering, confirm engine code (2.0 HDi RH02) and the vehicle model generation to ensure correct fitment.
