VAG 1J0906234 4-Way Female Radiator Fan Plug 

Includes terminals and seals

The Component: Genuine VAG 1J0-906-234 4-way automotive sealed female socket housing plug. 4-position single-row engine compartment flat contact housing receptacle casing (Black / PA66 / Sealed / Inline Shroud / Mechanical Snap-On Latch / Cross-Ref: 1J0906444 / Factory Alternative Code: 1071-4W).

Applications & Fitment: Designed as a high-capacity factory original equipment (OE) harsh-environment connection solution for heavy power delivery lines and engine cooling system networks across the Volkswagen Audi Group (VAG) platform grid. Most prominently specified as the definitive factory female plug interface for the main engine radiator cooling fan module and auxiliary electric fans. Universally found across classic and modern platforms, including the VW Golf (MK4, MK5), Jetta, Bora, Passat, Beetle, Eos, and Rabbit, alongside Audi A3, A4, A5, A6, and TT models, plus corresponding Skoda and Seat layouts. Engineered specifically to withstand high structural thermal loading and intense engine compartment harmonic vibration without casing degradation. Highly vulnerable to primary external mechanical thumb-latch locking clip snapping if forced roughly when brittle during cold-climate service cycles, or internal front silicone matrix face seal tearing if back-probed carelessly using raw, un-profiled multi-meter workshop diagnostic needles during field troubleshooting.
