VW / Audi 6-Pin Suspension Height Adjuster Wire Harness Connector – Male & Female OEM | Air Suspension

This 6-pin connector is used in Volkswagen and Audi air suspension height sensor and height adjuster harnesses. The 6-pin configuration integrates ride height sensor signal, sensor power, ground, and suspension control module communication circuits for VAG Group air suspension systems. Available in Male and Female variants, bare or with 15cm pre-wired leads.

• Pin 6 (DIAG): Sensor diagnostic / enable signal

VAG Air Suspension Systems

VAG Group uses air suspension (Luftfederung) across multiple premium models. The system uses air springs at each corner, a compressor, and height sensors to maintain a constant ride height regardless of load. The height sensors are rotary potentiometers or Hall effect sensors mounted on the suspension linkage — they measure suspension travel and send a voltage signal to the suspension control module.

Frequently Asked Questions

Q: My Audi/VW air suspension warning light is on but the car sits at normal height — is this the connector?
A: Yes. A corroded height sensor connector causes the suspension control module to receive an implausible signal, triggering the warning light even when the air springs are functioning correctly. Replace the connector and clear the fault code before replacing the height sensor ($80–$200) or the suspension control module ($400–$1,200).

Q: Are terminals included?
A: Yes, terminals are included with all variants.
