Intake Hose 1.6 e-HDI for Citroën and Peugeot Vehicles
Product Description
High-quality intake hose designed for 1.6 e-HDI Diesel engines used in Citroën and Peugeot models. This replacement hose restores correct air flow between the air filter box and the turbo/intercooler assembly (depending on specific vehicle layout), preventing intake leaks that cause poor throttle response, turbo lag and diagnostic fault codes. Frequently searched under OEM numbers 9684307360 and 0382NL, the part is suitable for both professional workshops and experienced DIY mechanics.

Fitment And Function
The intake hose is a critical component of the engine air supply system. It connects the airbox to the turbocharger or intercooler piping (vehicle dependent), ensuring sealed, vibration-resistant air transfer. A damaged or leaking hose allows unmetered air into the engine, which can upset fuel trim, reduce performance and trigger fault codes related to boost or intake pressure.
Replacement Procedure (Overview)
- Allow the engine to cool and ensure the vehicle is secure before starting work.
- Locate the intake hose between the air filter housing and turbo/intercooler plumbing.
- Loosen and remove clamps securing the hose; note orientation and any retaining brackets or clips.
- Carefully detach the hose, taking care not to damage adjacent sensors, wiring or vacuum lines.
- Inspect mating surfaces, turbo/intercooler connections and clamps; clean any oil or debris.
- Install the new hose in the correct orientation, replace worn clamps with new or OEM-quality clamps and tighten evenly until secure.
- Start the engine and check for leaks, proper boost build and absence of intake-related fault codes.
Installation Recommendations
- Always work on a cooled engine and wear appropriate PPE.
- Replace any aged or corroded clamps and retainers to ensure a long-term seal.
- Check for oil contamination from EGR or turbo seals; clean affected areas to prevent premature hose degradation.
- If unsure about turbo or sensor connections, document original routing before removal or take photos to ensure correct refit.
Why The Part Commonly Fails
Intake hoses typically degrade due to long-term exposure to heat, engine oil vapors, and mechanical stress from vibration. Common failure modes include cracks, hardening and split seams, clamp failure or deformation, and oil softening from EGR contamination. Vehicles with higher mileage or those that have experienced turbo or oil leaks are more prone to hose deterioration.
Notes For Mechanics And DIYers
This hose is commonly searched by its OEM references (9684307360, 0382NL) — including these codes in your search will help locate the correct part quickly. Inspect surrounding components (airbox seals, clamps, intercooler pipes) while replacing the hose to prevent repeat failures. Suitable for professional workshops and competent self-repair enthusiasts familiar with turbocharged diesel systems.
