Why this injector?

VW 1.6 TDI (CAYC)

Direct-fit replacement for the VW Group 1.6 TDI CAYC common-rail platform fitted to Golf, Passat, A3 and Octavia variants.
Flow-tested and calibrated on common-rail benches to match OEM spray pattern and return values.
Supplied with the correct electrical connector so no wiring-side modification is needed at fitment.
A practical option when diagnosing cold-start, rough-idle or elevated fuel-trim faults on CAYC engines.

OEM Variant & Compatibility Notes

A2C9626040080 is Continental's later-production primary for the Volkswagen Group EA189 1.6 TDI engine, directly superseding A2C59513554 from approximately 2013 onward. The fitment envelope is identical — bore, connector and seat profile match the earlier 554 — but the on-board flow-correction calibration map has been updated to align with the post-Dieselgate ECU revision rolled out across CAYA, CAYB, CAYC, CAYD, CAYE and CLNA fleets. It also covers later VW OE codes including 03L130277J and 03L130277KX.

This is the part number workshops most often search for directly, because it is what is currently stamped on EA189 injectors removed from later-build 2013-onward Audi A1 / A3 / Q3, Volkswagen Golf VII / Beetle / Caddy / Polo / Touran / Tiguan, Skoda Fabia / Octavia / Rapid / Yeti and SEAT Ibiza / Leon vehicles. After fitting, the individual flow-correction code printed on the injector body must be written into the ECU using VAG-COM / VCDS or the Volkswagen ODIS toolset — fitting without coding will trigger immediate cylinder balance fault codes.

Although A2C9626040080 sometimes appears in cross-reference tables alongside the PSA DV6C 1.6 HDi cluster, the bore profile and connector keying differ — never substitute for an A2C59513556 (DV6C) without confirming the OE marking on the failed unit.
