Part description

This hose / air connection to the exchanger is intended for turbocharged diesel engines 2.0 HDI in Citroën and Peugeot cars. In practice, it is a part of the intake and turbo system, which ensures the correct passage of compressed air between individual parts (typically connected to the exchanger). A properly sealed and undamaged hose is essential for stable engine performance and trouble-free operation without unnecessary air leaks.

The benefit of searching by number is quick identification: the key designation for this part is 0382AT (listed as NFP).

Installation recommendations

Generally/typically for intake and turbo hoses the exact location and access varies by specific car model and make. Below is a practical procedure for replacing this type of part.

1) Before assembly

• Compare the new part with the old part: shape, end diameters, length, routing and attachment/clip type.
• Check the hose for cracks, punctures, bulges or a deformed neck.
• Check the mating surfaces on the mating pieces (throats, nozzles) – they must not be dirty or damaged.

2) Necessary tools and materials

• Common hand tools (screwdrivers, socket wrenches depending on the type of clips/handles)
• Pliers for buckles (according to design)
• Cleaning agent and rags for cleaning contact surfaces
• Or new clips if the original ones are tired or deformed

3) Step-by-step assembly procedure

1. Allow the engine to cool and secure the vehicle against movement.
2. Get access to the hose in the intake/turbo area (depending on the specific car, it may be necessary to remove covers or surrounding parts).
3. Mark the position of the hose and line (e.g. with a photo) so that it does not come into contact with a sharp edge or hot part after assembly.
4. Release the clips/grips on both ends of the hose.
5. Remove the hose carefully from the throat – without force, so as not to damage the counterpart.
6. Check the counter parts and contact points, clean them of dirt and oil film residues.
7. Place the hose first on one end, then on the other, making sure it is properly seated all the way to the stop.
8. Place the buckles properly in their original position and tighten/snap them evenly.
9. Check that the hose does not pull anywhere, is not broken at the bend and does not rub against the surrounding parts.
10. Reinstall the removed covers/surroundings.

• 4) Post-assembly checks and test drive/function verification

  • Start the engine and check for air leaks (hissing) or loose connections at the connections.
  • After a short ride, visually check again the hose seating and the condition of the clips.

  5) The most common assembly mistakes + how to avoid them

  • Not tightened or poorly seated clips → always check the position of the clip on the throat and the tight pull.
  • Dirty contact surfaces → clean the grommets before assembly, the joint seals better.
  • Poor hose routing (contact with edge/heat) → check that the hose has the correct position and clearance before final tightening.
  • Using tired clips → if the clip does not hold securely, replace it so that the joint does not loosen over time.

  Reasons why the part is damaged

  • Aging of the material (swelling, loss of elasticity) due to heat in the engine compartment.
  • Working with pressure and vibration in the supercharger system – gradual loosening of joints and microcracks.
  • Contact with oil/oil mist in the intake can accelerate the degradation of rubber/plastic parts.
  • Mechanical wear on surrounding parts due to poor routing or missing grips.
  • Incompetent handling during previous repairs (prying, pulling the clip, damage to the neck).
