What is injector A2C59511612?
A Continental (Siemens VDO) solenoid common-rail diesel injector for the PSA 1.4 HDi (DV4) engine, shared with Ford 1.4 TDCi, Mazda 1.4 MZ-CD and Toyota 1.4 D-4D. PSA OE 9663429280.

Is it solenoid or piezo?
It is a Continental/Siemens VDO solenoid common-rail injector.
Does A2C59511612 need coding?
It depends on the ECU - later DV4 fitments use an injector classification code while early 8HX/8HZ units may not. Verify with PSA Lexia / Ford IDS when fitting.
What are the OE part numbers?
PSA 9663429280 and 1980L0, and Ford 2S6Q-9F593-BE (FINIS 1805488) reference this injector.
Does it fit the Toyota Aygo and Mazda 2 diesel?
Yes - the Aygo 1.4 D-4D and Mazda 2 1.4 MZ-CD use the PSA DV4 engine and the same Continental injector.
What are the symptoms of failure?
Rough idle, vibration, hard starting, black smoke, power loss/limp mode and an EML.
Why does my 1.4 HDi run rough?
A worn or leaking injector unbalances fuelling; read live back-leakage 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 A2C59511612 perform like new?
A properly remanufactured injector is bench-tested and recalibrated on a Continental-capable tester, then coded where the ECU requires it.
