A2C59511606 — Frequently Asked Questions
Verified answers about the Continental/Siemens VDO A2C59511606 1.5 dCi (K9K) Piezo Common Rail Injector (Renault/Nissan/Dacia).
What is injector A2C59511606?
A Continental (Siemens VDO) piezo common-rail diesel injector for the earlier Renault-Nissan K9K 1.5 dCi engine. Renault OE 166009445R/8200380253.
Which vehicles use A2C59511606?
Renault Clio III/Modus/Megane II/Scenic II/Kangoo, Nissan Micra K12/Note and Dacia Logan/Sandero 1.5 dCi (K9K).
Is it solenoid or piezo?
It is a Continental/Siemens VDO piezo common-rail injector.
How is it different from A2C59507596?
Both are K9K 1.5 dCi Continental injectors but for different sub-variants/eras - confirm the OE number (166009445R vs 166006212R) and engine code.
Does A2C59511606 need coding?
Yes - code the injector classification (C2I) code to the correct cylinder with CLIP/diagnostic when fitting.
What are the OE part numbers?
Renault 166009445R/8200380253 and Nissan 16600-00Q0H reference this 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 1.5 dCi 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 A2C59511606 perform like new?
A properly remanufactured injector is bench-tested and recalibrated on a piezo-capable tester, then C2I-coded on fitment.
