Key Functional Characteristics

• Voltage Rating: 12 V DC – compatible with standard automotive electrical systems.
• Current Capacity: 15 A – sufficient to handle the high current draw of modern fuel pumps.
• Pin Configuration: 4‑pin layout (common, coil terminals, and normally open/closed contacts) for straightforward integration into existing harnesses.
• Operating Temperature Range: –40 °C to +125 °C – ensuring reliable performance in both cold climates and hot engine compartments.
• Mechanical Life: >100,000 cycles – guaranteeing long‑term durability even under frequent switching conditions.

Design Features That Enhance Reliability

The relay incorporates a robust sealed contact design that minimizes arcing and wear. Its internal construction uses high‑grade copper contacts coated with gold to resist corrosion, while the housing is made from heat‑resistant plastic that protects against thermal shock.

Additionally, the Vemo V15-71-0018 includes a built‑in fuse protection within its circuitry. This feature safeguards the relay and downstream components by interrupting excessive current flow, thereby preventing damage to the fuel pump or wiring harnesses.

Compatibility Across Vehicle Platforms

This relay is engineered for seamless integration with a broad spectrum of vehicles. It matches the original equipment specifications for numerous models across major manufacturers such as Audi, Seat, Skoda, and Volkswagen. Whether your vehicle is a compact hatchback or a larger family car, the V15-71-0018 offers a reliable replacement that meets OEM standards.

Installation Guidelines

1. Disconnect the battery: Prior to any work on the electrical system, ensure the negative terminal is removed to eliminate the risk of short circuits.
2. Locate the existing relay: Typically found in the engine compartment’s fuse box or under a removable panel near the fuel pump assembly.
3. Remove the old unit: Carefully detach the relay, noting the orientation of pins and any mounting screws.
4. Insert the Vemo V15-71-0018: Align the pins with the corresponding terminals and secure it in place. Verify that the coil side is connected to the correct control circuit.
5. Reconnect the battery: Reattach the negative terminal and test the vehicle’s fuel system for proper operation.

Performance Benefits

• Consistent Fuel Delivery: By maintaining a stable electrical supply, the relay ensures that the fuel pump operates at its optimal pressure, contributing to smooth engine performance and efficient combustion.
• Reduced Maintenance Costs: The high durability of the V15-71-0018 means fewer replacements over the vehicle’s lifespan, saving time and money for owners and service technicians alike.
• Enhanced Safety: With its integrated fuse protection and corrosion‑resistant contacts, the relay mitigates the risk of electrical faults that could lead to fuel leaks or fires.

Quality Assurance & Manufacturing Excellence

The Vemo V15-71-0018 is manufactured in Germany, adhering to stringent quality control protocols. Each unit undergoes rigorous testing for voltage tolerance, current handling, and mechanical endurance before leaving the factory. This commitment to excellence guarantees that every relay performs reliably from day one.
