Special Features

  • [PRECISION SPECIFICATIONS] This 4H0951253 (644) power relay features a 4-pin SPST configuration rated for 12V 40A. It serves as a direct replacement for V23136-J0006-X079, engineered to maintain circuit integrity in high-demand powertrain systems
  • [EXTENSIVE COMPATIBILITY] Expertly designed to be compatible with Volkswagen Jetta, Golf, Tiguan, and Passat models. It also fits Audi A4, A5, A6, and Q5 series, integrating seamlessly into the engine bay E-Box or interior relay carrier
  • [DIAGNOSTIC SOLUTION] Effective at resolving "crank but no start" conditions and intermittent engine stalling. This relay addresses common fault codes such as P0688 (ECM Power Relay Sense Circuit) and P0230 (Fuel Pump Primary Circuit) caused by worn internal contacts
  • [REINFORCED CONSTRUCTION] Built with high-conductivity copper coils and silver alloy contact points to prevent internal welding during high-current surges. The heavy-duty housing exceeds standard rigorous testing for heat resistance and vibration stability in engine compartments
  • [MAINTENANCE RELIABILITY] This multi-pack provides essential spares for terminal 30 load reduction, horn, or cooling fan circuits. The standard ISO terminal layout allows for a plug-and-play installation without the need for harness modification

Description

Restore Stable Electrical Performance to Your Powertrain Circuit
Is your vehicle suffering from unexpected stalling or communication drops in the ECM? The 4H0951253 (644) Relay is a critical switching component responsible for delivering clean power to the fuel pump and engine control module. By replacing a carbon-fouled factory relay, you restore the reliable performance needed for consistent ignition and fuel delivery.
Reliable Engineering for German-Designed SystemsConstructed to withstand the extreme thermal cycles of the engine bay, this 40-Amp relay ensures a stable current flow even under maximum load. It is a compatible replacement for the 644 series found in various terminal 30 and fuel system applications. The silver-alloy contacts are specifically designed to resist pitting, providing a significantly longer service life than generic alternatives.
Typical Application Scenarios:
Fuel System: Compatible with Volkswagen Jetta and fits Audi A4 fuel pump power supply.

Engine Management: Power supply for the ECM/PCM and load reduction circuits.

Auxiliary Systems: Controls secondary air injection, cooling fans, and horn systems.

Installation & Verification:To ensure a precise fit, please verify the "644" or "4H0 951 253" stamp on your existing relay housing. This 12V 40A SPST switch is designed for standard 6.3mm sockets. Ensure the pins are fully seated to maintain a vibration-resistant connection in your vehicle's fuse relay center.
