644 4H0951253 V23136-J0006-X079 Relay 12V 40A 4-Pin SPST (4-Pack) Compatible with Select Volkswagen Jetta GTI Tiguan Passat and Audi A4 Q5 A6 Applications

4-Pack 644 Relay Replacement for Matched Automotive Electrical CircuitsThis 644 / 4H0951253 / V23136-J0006-X079 relay is a 12V 40A 4-pin SPST automotive power relay designed for matched relay sockets and compatible 12V electrical circuits. It is intended for applications that use the same relay code, terminal layout, housing shape, and relay position.Compatible with Select Vehicle Applications:Compatible with select Volkswagen Jetta applicationsCompatible with select Volkswagen GTI applicationsCompatible with select Volkswagen Tiguan applicationsCompatible with select Volkswagen Passat applicationsCompatible with select Audi A4 applicationsCompatible with select Audi Q5 applicationsCompatible with select Audi A6 applicationsInterchange Part Numbers / Replacement References:644, 4H0951253, 4H0 951 253, V23136-J0006-X079, V23136 J0006 X079, TY6Application Notes:This relay may be used in matched relay-controlled circuits such as fuel pump, ECM power supply, terminal 30, horn, cooling fan, secondary air injection, headlight, or other 12V automotive electrical systems. Actual use depends on the original relay code, relay box location, socket design, and vehicle application.Important Buyer Warning:Please count your original relay pins and compare the part number, relay code, socket shape, voltage, amperage, terminal layout, printed markings, and relay box location before purchase. This listing is for a 4-Pin aftermarket relay. It is not a universal relay. Fitment may vary by year, trim, engine, relay position, and circuit function.This relay may help restore normal circuit operation only when the original relay is confirmed faulty and the specifications match. P0688, P0230, stalling, crank-no-start, fuel pump, or ECM power symptoms may also be caused by wiring, fuses, sensors, pumps, batteries, grounds, control modules, or other components. Proper diagnosis is recommended before replacement.Package includes 4 relays for replacement, maintenance stock, or backup use.

• 4-Pin Relay Verification: 4-Pin 12V 40A SPST relay — please verify your original relay code, pin layout, socket shape, terminal position, and relay box location before ordering. Not for 5-pin relays or different connector patterns
• Match the Original Relay Code: Designed for matched 644 / 4H0 951 253 / V23136-J0006-X079 relay applications. Please compare the printed marking, green housing style, blade terminal layout, and socket orientation before purchase
• Stable 12V Circuit Switching: Helps support normal relay-controlled power transfer when the original relay is confirmed faulty and the specifications match. Avoid replacing parts before confirming the relay is the actual failure point
• Selective Circuit Applications: May be used in compatible fuel pump, ECM power supply, terminal 30, horn, cooling fan, secondary air injection, headlight, or other 12V relay-controlled circuits depending on vehicle application
• 4-Pack Garage Backup Set: Includes 4 relays for multiple relay positions, maintenance stock, or backup use. P0688, P0230, stalling, no-start, or power-loss symptoms may also come from wiring, fuses, sensors, pumps, modules, or other components
