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.
