Description

  • FUNCTIONAL OEM REPLACEMENT: Direct-fit replacement for the 645 multi-purpose relay (Part # 4H0951253A). Utilizes a standard 4-pin layout (Terminals 30, 85, 86, 87) to ensure a secure connection within the original equipment fuse box of your vehicle.
  • SYSTEM APPLICATIONS: Suitable for controlling essential automotive components such as the fuel pump, starter motor, radiator cooling fan, and horn. Compatible with various VAG group vehicles from 2008 to 2025 that require a 12V 40A normally open relay.
  • ELECTRICAL INTEGRITY: Built with an internal resistor to manage voltage spikes when the relay de-energizes. This technical feature helps maintain the stability of the vehicle's sensitive electronic modules during frequent switching cycles.
  • ENGINE STALL RESOLUTION: Designed to help fix engine stalling or no-start conditions related to relay fatigue. By restoring reliable voltage to the fuel system, this relay addresses the root cause of many "Check Fuel System" dashboard warnings.
  • EASY PLUG-AND-PLAY: No specialized tools or wiring modifications are required for installation. Each unit is load-tested to ensure it meets functional performance standards, offering a cost-effective solution for DIY automotive electrical repairs.
