Description
Turbo air hose for Citroën and Peugeot 2.0 HDi and 2.2 HDi engines. Suitable for Citroën C5, C5 X7 or Peugeot 407.
This turbo air hose is the pressurised connection between the turbocharger and the intercooler (intercooler inlet/outlet), designed for 2.0 HDi and 2.2 HDi diesel engines. It restores correct boost delivery, reduces pressure losses and helps maintain engine performance and fuel efficiency. The part is commonly referenced by the manufacturer code 0382LA and is often searched by mechanics and DIY car owners by this product number.
Replacing a worn or leaking turbo air hose brings immediate drivability improvements: smoother acceleration, restored boost response and elimination of whistling or hissing noises under load. The hose is made to withstand engine bay temperatures and pressure cycles, but it must remain free of cuts, hardening or oil saturation to function correctly.

Installation Recommendations
- Work On A Cold Engine: Allow the engine to cool before starting to avoid burns and ensure clamps can be removed safely.
- Relieve Boost Pressure: Run the engine briefly and then let it sit or follow vehicle-specific procedures to avoid trapped pressure when loosening connections.
- Inspect Surrounding Components: Check intercooler, turbocharger outlet and intake elbow for oil residue, cracks or foreign debris before fitting the new hose.
- Use New Clamps: Replace old worm-drive or spring clamps with quality replacements and tighten evenly to avoid pinching the hose.
- Ensure Correct Seating: Push the hose fully onto the mating spigots and align so there is no torsion or sharp bend that could shorten service life.
- Perform A Boost Test After Installation: Start the engine and perform a boost check or listen for leaks while revving in neutral to confirm a secure seal.
Why This Part Fails Most Often
- Ageing And Hardening: Rubber and silicone hoses stiffen and crack over time, leading to boost leaks.
- Oil Contamination: Turbo leakage or over-oiling introduces oil into the hose, softening materials and promoting deterioration.
- Heat And Vibration: Continuous exposure to high temperatures and engine vibration weakens hose walls and causes splits or separation at joints.
- Poor Clamping Or Installation: Loose or damaged clamps and incorrectly seated hoses are common causes of air leaks.
There is no fixed replacement interval for the turbo air hose; service life depends on driving conditions, maintenance and mileage. Failures are most common on older vehicles or cars with elevated oil consumption from turbo wear. For reliable results, replace the hose at the first sign of cracking, oil saturation or boost loss and always fit with quality clamps and clean mating surfaces.
