3A00973834 / 3A097373 Automotive 8-Pin Diesel Common Rail Connector — Fuel Injector & Crankshaft Sensor Plug for VW

In a diesel common rail fuel injection system, connector integrity is non-negotiable. A degraded injector connector can cause misfires, rough running, excessive smoke, and fault codes that are difficult to diagnose without first ruling out the wiring harness. The 3A00973834 / 3A097373 8-pin diesel common rail connector is the OEM-specification solution for Volkswagen diesel fuel injector nozzle plug and crankshaft sensor wiring harness repair — engineered to withstand the extreme heat, fuel vapour, and vibration of the diesel engine bay.

Built from high-temperature PA66 nylon with tin-plated copper alloy contacts, this connector maintains reliable electrical continuity at the injector and crankshaft sensor interface across the full service life of the engine. Whether you're diagnosing a P0201–P0204 injector circuit fault or replacing a heat-damaged crankshaft sensor connector on a VW TDI, the 3A00973834 / 3A097373 provides the dimensional accuracy and thermal resistance of the original OEM part.
