The Siemens/VDO 03L130277B injector is used across verified Audi, SEAT, Škoda and VW 1.6 TDI applications. TecDoc lists 79 vehicle links covering CAYA, CAYB, CAYC, CAYD, CAYE and selected CLNA engines.
Matching 03L130277B, 03L130277S and 03L130277SX
OE number 03L 130 277 B is listed for Audi, SEAT, Škoda and VW. The same OE family also includes 03L 130 277 S and exchange reference 03L 130 277 SX. Always compare the number on the removed injector; searching by “1.6 TDI” alone is not precise enough.

Engine-code and fitment checks
The previous CAYA-only focus was too narrow. Verified applications also include CAYB, CAYC, CAYD and CAYE, with CLNA on selected SEAT and Škoda variants. Match the OE number, engine code, power output, production period and old-unit markings. Compare the connector, body and leak-off connection as well.
Diagnosis before injector replacement
Hard starting, rough idle, smoke, loss of power or unusual correction values can indicate injector wear. Similar symptoms can also come from rail-pressure, EGR, air-mass or compression faults. A leak-off test and live-data checks help establish the cause before parts are replaced.
Product page and full vehicle selector
Product details and the complete fitment check are available on the 03L130277B / 03L130277S Siemens/VDO injector page. Confirm the exact engine variant there before ordering.
Frequently asked questions
Does 03L130277B only fit the CAYA engine?
No. TecDoc also lists CAYB, CAYC, CAYD and CAYE, plus CLNA on selected variants. Final approval depends on the OE number and vehicle data.
Which makes use 03L130277B?
The 79 vehicle links cover Audi, SEAT, Škoda and VW, including A1, A3, Altea, Ibiza, Fabia, Octavia, Caddy, Golf, Polo and Touran families.
What are 03L130277S and 03L130277SX?
They are additional OE or exchange references in the same injector family. The old-unit marking and exact TecDoc vehicle link remain decisive.
Is 1.6 TDI enough information to order?
No. The 1.6 TDI family contains several engine codes and power outputs. Check OE number, engine code, production period and the removed injector together.
