Cross-Reference Explained – Three Part Numbers, One Connector

The three OEM part numbers reflect the multi-supplier nature of VAG Group’s connector sourcing:

• 1719105-2 (TE Connectivity): The connector manufacturer’s part number. TE Connectivity (formerly Tyco Electronics / AMP) is one of the world’s largest connector manufacturers and supplies this connector to VAG Group as OEM.
• 1J0973737 (VAG Female): VW Group’s own part number for the female housing in the VAG parts catalog (ETKA). The 1J0 prefix indicates this connector was originally designed for the VW Golf IV (1J) platform.
• 1J0973837 (VAG Male): VW Group’s part number for the male housing. Despite the Golf IV origin prefix, this connector is used across multiple VAG Group platforms.

Frequently Asked Questions

Q: How do I find the correct part number for my vehicle?
A: Use ETKA (VW/Audi electronic parts catalogue) with your vehicle’s VIN to find the exact headlight assembly part number, then cross-reference to the connector part number. Alternatively, check the part number stamped on your existing connector housing.

Q: What is the difference between Type A and Type B female housings?
A: Type A (1J0973737) and Type B use different housing geometries to prevent mis-mating between left and right headlight assemblies or between different headlight module generations. Match the type to your existing connector housing geometry.

Q: What fault codes indicate a failed headlight connector?
A: Common codes on VCDS include B-codes for xenon ballast circuit faults, AFS module communication errors, headlight leveling motor circuit faults, and LED driver errors. Multiple simultaneous B-codes from a single headlight are a strong indicator of connector degradation.
