Fitment And Compatibility
Compatible with a range of 1.6 e-HDi diesel models from Citroën and Peugeot listed above. Always check the stamped or printed OE number on the original part against the product codes when searching to ensure correct fitment.
Function And Benefits
- Connects the turbocharger to the intake/intercooler system, maintaining sealed airflow under boost.
- Prevents boost leaks that lead to power loss, turbo lag and increased smoke or poor idling.
- OE-fit design for correct dimensions and secure fastening where original clamps and sensors attach.
- Easy replacement improves drivability and preserves turbocharger performance.
Replacement Procedure
- Prepare: Park on level ground, allow engine to cool and switch ignition off.
- Access: Remove engine covers or components obstructing access to the turbo intake connection.
- Release Pressure: Ensure there is no residual boost pressure before loosening clamps.
- Disconnect: Loosen clamps and carefully disconnect any attached vacuum lines or sensor plugs, noting their position.
- Remove: Remove the old connection, clean mating surfaces and inspect adjoining pipes, sensor fittings and clamps for damage or corrosion.
- Install: Fit the new intake connection in the correct orientation, replace worn clamps or seals, and tighten clamps evenly until secure—avoid overtightening.
- Check: Reconnect sensors and lines, start the engine, and check for air leaks at idle and under light load. Perform a short test drive to confirm proper boost response.
Recommended Installation
Use new stainless or high-quality clamps and replace any hardened O-rings or gaskets. Lubricate seal lips lightly for easier assembly and alignment. If uncertain about sensor reconnection or if additional components must be removed for access, have the replacement performed by a qualified technician. After installation, inspect for leaks and correct clamp torque; road-test to ensure normal turbo response.
Why The Part Commonly Fails
- Ageing And Heat Exposure: Repeated thermal cycles harden and crack rubber or elastomeric materials.
- Oil Contamination: Turbo oil leaks or blow-by can degrade hose material and cause swelling or soft spots.
- Clamps And Fastener Corrosion: Loose or corroded clamps allow the connection to slip or leak under boost.
- Mechanical Damage: Contact with adjacent components or improper installation can tear the coupling.
Expected Service Life
Typical service life depends on driving conditions and maintenance. Under normal use, intake couplings often last several years; a practical replacement interval is considered around 5–10 years or roughly 100,000–150,000 km, but inspect the part earlier if the vehicle runs hot, carries heavy loads or shows symptoms of boost loss.
Notes For Buyers
Customers often search by OE numbers: 9673593680, 9677815380, 1434H0. Selecting the correct product code ensures direct replacement and fitment with original mounting points and sensor locations.
