PSA 2.0 HDi (RHY) Remanufactured Common Rail Injector
RHY
Hard starting, particularly when warm; uneven idle; loss of power with rail-pressure faults; excess smoke under acceleration; engine stalling at idle. When two or more appear together, suspect the injector before peripherals — a comparative leak-off test isolates the failed unit without tear-down.
Injector back-leak beyond specification on high-mileage units; nozzle wear causing over-fuelling and smoke; fuel contamination damage on neglected systems. Internal wear cannot be repaired in situ — once delivery drifts outside calibration, remanufacture or replacement is the reliable fix.
This is an early common-rail platform — verify low-pressure supply and check for air ingress before condemning injectors. Run a comparative leak-off test across all four injectors. Use new sealing washers on every refit. Never condemn a common-rail injector on a fault code alone.
Each remanufactured 5WS40000-Z is fully stripped, ultrasonically cleaned and inspected; worn components are replaced with OE-grade parts. The rebuilt unit is calibrated on a common-rail test bench against the manufacturer's specification — delivery, back-leak and response verified — and despatched with a 12-month parts warranty and its calibration data on file.
The 5WS40000-Z trusted family covers 10 verified vehicle fitments across 3 makes: Citroen, Fiat and Peugeot. Every fitment listed is registry-verified.
5WS40000-Z cross-references 9 further OE numbers, including R5WS40000, 9636819380, 9652173780, 9652173680, 9636680280, 1980F0, 00001980F0 and 1980Y0. Always match the reference etched on your failed unit's body.
