03L130277B — Technical Research
03L130277B is the original VW Group (VAG) OE part number for the Continental / Siemens VDO solenoid common-rail injector fitted to the 1.6 TDI CAY-series engines (CAYA/CAYB/CAYC/CAYD/CAYE and later CLNA) across VW, Audi, Seat and Skoda. VAG later superseded this number to 03L130277S — the two numbers identify the same injector position and the S-suffix part is the current replacement. The Continental manufacturer number for this injector is A2C9626040080, and the Bosch counterpart reference for the same engine is 0445110369.
VAG OE 03L130277B — Continental/Siemens 1.6 TDI Common Rail Injector (superseded by 03L130277S)
03L130277B is the original VW Group (VAG) OE part number for the Continental / Siemens VDO solenoid common-rail injector fitted to the 1.6 TDI CAY-series engines (CAYA/CAYB/CAYC/CAYD/CAYE and later CLNA) across VW, Audi, Seat and Skoda. VAG later superseded this number to 03L130277S — the two numbers identify the same injector position and the S-suffix part is the current replacement. The Continental manufacturer number for this injector is A2C9626040080, and the Bosch counterpart reference for the same engine is 0445110369.
- identification03L130277B and 03L130277S are interchangeable order numbers for the same injector — if your engine currently runs B-suffix injectors, an S-suffix (or the Continental A2C9626040080) unit is the correct replacement.
- InstallationCode the 7-digit IMA correction value to the correct cylinder with VCDS/ODIS after fitting; mixing B and S suffix units across cylinders is acceptable provided each is coded.
What is the difference between 03L130277B and 03L130277S?+
There is no functional difference for replacement purposes: 03L130277S is the VAG supersession of 03L130277B. VW Group replaced the B-suffix order number with the S-suffix; both identify the Continental/Siemens common-rail injector for the 1.6 TDI CAY-series engines.
What replaces 03L130277B?+
03L130277S is the current VAG order number, and A2C9626040080 is the Continental (Siemens VDO) manufacturer number for the same injector. A remanufactured A2C9626040080 unit is a direct replacement for injectors originally supplied as 03L130277B.
Can I mix 03L130277B and 03L130277S injectors on the same engine?+
Yes — they are the same injector under different order numbers. Each injector must still have its individual IMA correction value coded to its cylinder after fitting.
Which vehicles use 03L130277B?+
VW Group 1.6 TDI (CAYA/CAYB/CAYC/CAYD/CAYE, later CLNA) applications including VW Golf, Polo, Passat and Caddy, Audi A1 and A3, Seat Ibiza, Leon and Altea, and Skoda Fabia, Octavia and Superb.
