Does A2C59511603 need coding?
Yes - code the injector correction value to the correct cylinder with PSA Lexia / Ford IDS when fitting.
What are the OE part numbers?
PSA 9656389980 and 1980K3/1980W6 reference this injector; the Delphi equivalent is EJBR03801D and the Bosch cross is 0986438003.
Is the Delphi EJBR03801D the same injector?
It is the Delphi equivalent for the same DW10BTED4 2.0 HDi application - confirm the OE number and engine code before fitting.
What are the symptoms of failure?
Rough idle, vibration, hard starting, black smoke, power loss/limp mode and an EML.
Why does my 2.0 HDi run rough?
A worn or leaking injector unbalances fuelling; read live cylinder-contribution data and bench-test the suspect cylinder.
What causes these injectors to fail?
Poor fuel filtration, contamination and back-leakage wear - fix the cause first.
Does a remanufactured A2C59511603 perform like new?
A properly remanufactured injector is bench-tested and recalibrated on a Continental-capable tester, then coded on fitment.
