Pin Assignment Reference (6-Pin Sensor/Actuator)

VW Part Number Decoding – 3B0 vs 4H0

3B0 = Passat B5 platform; 4H0 = Audi A8 (D4) platform. Despite different platform prefixes, both use the same 1.5mm pitch 6-pin housing format and are cross-compatible for harness repair.

Compatible Applications

• VW Passat B5/B6: Sensor and body harness connectors
• Audi A4 (B6/B7) / A6 (C6) / A8 (D4): ECU sub-harness and sensor connectors
• Skoda Octavia / Superb / SEAT: Sensor and actuator harness connectors

Diagnosis

• Intermittent sensor codes after rain: Inspect wire seal – moisture ingress causes intermittent open-circuit faults
• VW/Audi fault codes: 01314 (Engine Control Module), 00668 (Supply Voltage Terminal 30) – check connector before replacing modules
• VCDS live data: Erratic or stuck sensor reading indicates connector fault, not sensor fault

FAQ

Q: Can this be used on Skoda and SEAT?
A: Yes – VW Group 1.5mm connectors are shared across VW, Audi, Skoda, and SEAT platforms.
