645 Relay 4H0951253A V23136-B0006-X080 (4-Pack) 12V 40A 4-Pin SPST Automotive Power Relay Compatible with Volkswagen Jetta Tiguan and A4 Q5 Fixes Fuel Pump and Engine Stalling

Are you dealing with an engine that stalls intermittently or a fuel pump that fails to engage?The 645 Power Relay (4H0951253A) is a vital component in your vehicle’s electrical chain, acting as the gatekeeper for high-amperage powertrain circuits. Over years of use, factory relays develop internal resistance and carbon buildup. This professional-grade relay set restores precise switching to your ignition and fuel systems, ensuring your vehicle remains dependable.Precision Engineering for High-Load Automotive CircuitsDesigned to handle the intense heat of engine bay fuse boxes, these relays feature upgraded internal components that resist contact welding. They are a reliable replacement for original relays in vehicles compatible with Volkswagen, and fits Porsche. Replacing these high-load components often resolves persistent fault codes like P0230 (Fuel Pump Circuit) and P0688 (ECM Power) without expensive dealership diagnostics.Applications Include:Powertrain Management: Compatible with Volkswagen Jetta and fits A4 fuel pump power circuits.Thermal Control: Manages radiator cooling fans for models compatible with Tiguan and fits Q5.Chassis Systems: Compatible with Porsche Cayenne power distribution.Ignition Support: Restores integrity to Terminal 15 and Terminal 30 circuits.How to Choose:Before installation, verify the "645" stamp on the top of your original relay and confirm the 4-pin layout with OE part number 4H0951253A. Ensure the relay seats firmly into the socket for a vibration-resistant connection in your vehicle’s electrical panel.

• [HEAVY-DUTY SPECS] This 12V 40A 4-pin SPST power relay is a functional replacement for OE part number 4H0951253A and V23136-B0006-X080. It features silver-tin oxide contacts to manage high-amperage surges while maintaining consistent circuit switching integrity.
• [BROAD COMPATIBILITY] Expertly engineered to be compatible with Volkswagen Jetta, compatible with Volkswagen Tiguan, fits A4, fits Q5, and fits Porsche Cayenne models. It integrates into factory fuse panels for terminal 15 and terminal 30 power systems.
• [FIXES COMMON ISSUES] Restores reliable power supply to solve intermittent engine stalling and "no-start" conditions. Effectively clears diagnostic fault codes such as P0230, P069E, and P0480 related to power delivery malfunctions in the fuel pump or engine control module circuits.
• [PREMIUM BUILD] Constructed with heat-resistant PA66 nylon housing designed to survive engine bay temperatures up to 257 degrees F. The high-conductivity internal electromagnetic coils provide a stable connection, preventing erratic clicking sounds or parasitic battery drain.
• [MAINTENANCE RELIABILITY] This set provides four units for a full system refresh of aging relays in the ignition, cooling fan, or horn circuits. Replacing multiple relays simultaneously helps maintain balanced electrical resistance across your vehicle’s wiring harness.
