Description
Air Connection 2.0 HDi For Citroën And Peugeot Vehicles
Product Overview
This used air intake/charge-air hose is designed for 2.0 HDi diesel engines found in select Citroën and Peugeot models. Supplied under code 0382AS (Stellantis), the hose routes compressed air between the turbocharger/intercooler and the intake manifold, ensuring correct boost delivery and engine response. Ideal For Professional Mechanics And Skilled Do-It-Yourself Enthusiasts Looking For A Direct-Fit Replacement.
Key Benefits
- Direct Fit For Compatible 2.0 HDi Engines — Simplifies Replacement And Reduces Downtime.
- Restores Proper Boost Pressure And Throttle Response When Original Hose Is Cracked Or Leaking.
- Saves Time Compared To Sourcing New OE Parts When Matching Part Number 0382AS Is Required.
Symptoms Of A Faulty Hose
- Loss Of Engine Power, Poor Acceleration, Or Hesitation Under Boost.
- Intermittent Or Constant Overboost/Underboost Diagnostic Trouble Codes (DTCS) And Turbo-Related Faults.
- Whistling Or Hissing Sounds From Engine Bay, Especially Under Acceleration.
- Rough Idle Or Increased Smoke If Air/Fuel Mixture Is Affected.
How The Part Functions
The hose carries pressurised air from the turbo/intercooler assembly to the intake manifold. It must remain airtight and flexible to accommodate engine movement and thermal cycles. Any crack, split, or loosened clamp can create a boost leak, causing incorrect air metering and drivability issues.
How To Replace (Basic Guide)
- Work On A Cold Engine In A Well-Ventilated Area And Wear Appropriate Safety Gear.
- Locate The Defective Hose And Note Clamp Positions Or Any Attached Vacuum Lines/Sensors.
- Loosen Hose Clamps Or Remove Clamps/Clips Carefully; Detach Any Sensors Or Small Hoses First.
- Remove The Old Hose, Clean Mating Surfaces, And Inspect Connecting Pipes For Damage Or Corrosion.
- Fit The Replacement Hose In The Correct Orientation, Reattach Sensors/Lines, And Secure With New Or Serviceable Clamps.
- Start The Engine, Check For Leaks Under Load, And Verify Turbo/Boost Behaviour During A Road Test.
Installation Recommendations
- Use Quality Worm-Drive Or Crimp Clamps; Replace Old Clamps When Corroded Or Deformed.
- Inspect Adjacent Components (Turbo Outlet, Intercooler Pipes, Vacuum Lines) For Wear While Replacing The Hose.
- Ensure Proper Routing To Avoid Chafing Against Hot Or Moving Parts; Trim If Necessary To Prevent Rubbing.
- After Installation, Clear Relevant Fault Codes And Perform A Boost Leak Check If Possible.
Most Common Failure Reasons
- Ageing Rubber And Repeated Heat/Cool Cycles Causing Cracks Or Hardening.
- Oil Contamination From Turbocharger Leaks Leading To Material Swelling And Softening.
- Excessive Boost Or Improperly Tuned Engines Increasing Stress On Hose Joints.
- Poorly Fitted Or Corroded Clamps Allowing Hose Movement And Abrasion.
