A2C59511316 — Technical Research
Continental (Siemens VDO) piezo common-rail injector for the 2.7 V6 diesel (DT17 / LION V6 / 276DT) shared by Jaguar, Land Rover, Peugeot and Citroen. Siemens equivalent 5WS40103; PSA OE 9657144580. Replacements are coded to the ECU with the injector classification code. Failures are driven by poor fuel filtration, contamination and back-leakage. Key symptoms: Rough idle / vibration; Hard starting; Loss of power / limp mode; Black smoke. Common failure modes: Internal wear / high back-leakage; Piezo stack degradation; Nozzle coking.

A leaking injector unbalances cylinder fuelling on the 2.7 V6.
Excess back-leakage drops cranking rail pressure.
Out-of-range delivery or rail-pressure deviation cuts power.
Poor atomisation over-fuels the cylinder.
Cylinder-specific injector or fuel-metering codes.
- InstallationCode the injector classification code to the correct cylinder with the relevant diagnostic (JLR SDD / PSA Lexia) before road test.
- InstallationRenew the copper combustion washer and leak-off seals; torque the clamp to spec - V6 banks make access tight.
- MisdiagnosisSeveral 2.7 V6 Siemens part numbers exist (e.g. A2C59511364) - confirm the exact number and classification before fitting.
- WarningFix contamination (filter/water/debris) first - the 2.7 V6 is sensitive to fuel quality.
- TestingBench-test on a piezo-capable CR tester; verify response and spray pattern before refit.
What is injector A2C59511316?+
A Continental (Siemens VDO) piezo common-rail diesel injector for the 2.7 V6 diesel (DT17/LION V6/276DT) used by Jaguar, Land Rover, Peugeot and Citroen. Siemens equivalent 5WS40103.
Which vehicles use A2C59511316?+
Land Rover Discovery III/Range Rover Sport, Jaguar S-Type/XF/XJ 2.7D, Peugeot 607/407 and Citroen C5/C6 2.7 HDi.
Is it solenoid or piezo?+
It is a Continental/Siemens VDO piezo common-rail injector.
Does A2C59511316 need coding?+
Yes - code the injector classification code to the correct cylinder with JLR SDD / PSA Lexia when fitting.
What are the OE references?+
PSA OE 9657144580 and the Siemens equivalent 5WS40103 reference this injector; A2C59511364 is a related 2.7 V6 number.
Is the 2.7 TDV6 hard to work on?+
Access to the V6 banks is tight; plan for additional labour and always renew seals and torque the clamps correctly.
What are the symptoms of failure?+
Rough idle, vibration, hard starting, black smoke, power loss/limp mode and an EML.
Why does my 2.7 TDV6 run rough?+
A worn or leaking injector unbalances fuelling; read live cylinder-balance data and bench-test the suspect cylinder.
What causes these injectors to fail?+
Poor fuel filtration, contamination and back-leakage wear plus piezo-stack ageing - fix the cause first.
Does a remanufactured A2C59511316 perform like new?+
A properly remanufactured injector is bench-tested and recalibrated on a piezo-capable tester, then coded on fitment.
