EGR Valve Pin Assignment (6-Pin)

1J0973713G – VW Part Number Suffix Decoded

The VW part number 1J0973713G follows the standard VW Group format: 1J0 = Golf IV / Jetta IV / Bora platform; 973713 = connector housing; G = 6-pin variant (A=1-pin, B=2-pin, C=3-pin, D=4-pin, E=5-pin, F=5-pin alt, G=6-pin). This letter suffix system is consistent across VW Group connector part numbers.

Compatible VW / Audi Applications

• VW Golf IV / Jetta IV / Bora (1J, 1997–2006): EGR valve and throttle body harness connector
• Audi A3 (8L) / A4 (B5/B6): EGR valve and sensor harness connector
• Skoda Octavia (1U): EGR valve harness connector

Diagnosis – EGR Valve Faults

• P0400–P0409 (EGR Circuit): Inspect 1J0973713G connector before replacing EGR valve – a corroded terminal is a common root cause on VW/Audi
• P0403 (EGR Control Circuit): Check Pin 4 (PWM control signal) – an open circuit prevents the ECU from controlling EGR valve position
• VCDS live data: Monitor EGR valve position (G212) in real time – a stuck or erratic reading indicates connector fault before replacing the valve

FAQ

Q: Is 42121200 the same as 1J0973713G?
A: Yes – 42121200 is an aftermarket cross-reference number; 1J0973713G is the VW OEM part number for the same connector. Both refer to the identical 6-pin 1.5mm waterproof connector.

Q: What does the ‘G’ suffix mean on VW connector part numbers?
A: The letter suffix on VW connector part numbers indicates the pin count: A=1, B=2, C=3, D=4, E=5, G=6. So 1J0973713G = 6-pin variant of the 1J0973713 connector family.
