A2C59513484 — Frequently Asked Questions
Verified answers about the Continental VDO A2C59513484 (H8200704191) Renault/Nissan 1.5 dCi K9K Piezo Injector.
What is injector A2C59513484?
A Continental (Siemens VDO) piezo common-rail injector for the Renault-Nissan K9K 1.5 dCi engine. Siemens/Renault number H8200704191 / 8200704191; OE 166009445R.
Which vehicles use A2C59513484?
K9K-engined Renault Clio/Megane/Scenic/Kangoo, Nissan Qashqai/Juke/Note, Dacia Duster/Sandero/Logan and Mercedes A/B-Class with the K9K engine.
Is it a piezo or solenoid injector?
It is a piezoelectric injector and needs a Siemens/VDO/Continental-capable bench.
What is the Renault number for A2C59513484?
H8200704191 / 8200704191, with OE references 166009445R and 166008052R.
Do I need to code the injector after fitting?
Yes - K9K injectors require coding/calibration so the ECU can compensate for manufacturing tolerances, or the engine runs rough.
What are the symptoms of a failing K9K injector?
Rough idle/vibration, hard starting, misfire and power loss, black smoke, higher fuel consumption and injector knock.
What fault codes are linked to this injector?
Injector-circuit codes P0201-P0208 plus misfire codes are common; read them with a diagnostic tool to confirm the cylinder.
How do I find the faulty injector?
Read injector correction values - corrections beyond roughly +/- 2.5 mg/stroke point to a faulty injector before removal.
Can I test A2C59513484 on a Bosch bench?
No - it is a Continental/Siemens piezo injector and requires a Siemens/VDO/Continental-capable bench.
Should I replace one or all four?
Diagnose each with correction values and a bench test; on high-mileage K9K engines failures often cluster, so check all four.
Why renew the copper washer?
It is a one-use crush seal; reusing it risks carbon 'asphalt' build-up and blow-by around the injector.
Does a remanufactured A2C59513484 perform like new?
A properly remanufactured piezo injector is bench-tested and recalibrated to the Continental plan to meet original delivery and leak-back specs.
