VEMO V15-71-0017 Relays

VEMO V15‑71‑0017 Fuel Pump Relay

The VEMO V15‑71‑0017 is a high‑performance, 12 V automotive relay designed specifically for controlling the fuel pump in a wide range of Volkswagen Group vehicles. It delivers reliable operation under demanding conditions and ensures that the fuel system receives the correct electrical signal to maintain optimal engine performance.

Key Technical Specifications

• Voltage Rating: 12 V DC
• Current Capacity: 30 A (continuous)
• Pin Configuration: 5‑pin, standard automotive relay layout
• Operating Temperature Range: –40 °C to +125 °C
• Dimensions: 22 mm × 15 mm × 10 mm (typical)
• Mounting Type: Screw‑in, compatible with OEM harnesses
• Seal Quality: IP54 protection against dust and water spray

Design Features That Enhance Reliability

The relay incorporates a stainless steel armature that resists corrosion, ensuring long‑term durability even in harsh automotive environments. Its high‑quality contacts are engineered to minimize arcing and wear, which is critical for the frequent switching required by fuel pumps.

The relay’s compact footprint allows it to fit into tight engine bay spaces without requiring modifications to existing harnesses or brackets. The 5‑pin layout matches standard VEMO and OEM connectors, simplifying installation and reducing the risk of wiring errors.

Compatibility Across Volkswagen Group Models

The V15‑71‑0017 is engineered for a broad spectrum of vehicles, including:

• Audi: A6, A4, 100, Coupe, 80, C5, B5, C4, 8B, 2.0 E quattro models
• Volkswagen: Passat (including Variant and 3B6), Polo, Golf (II & III), Transporter, Caddy II, Sharan, Vento, Corrado, Golf Cabriolet
• Seat: Cordoba, Ibiza II, Toledo I, A6, A4, 100, Coupé, 80, C5, B5, C4
• Ford (VAG Group): Focus on models sharing the same fuel pump architecture as VW/Seat/Audi platforms

Because of its universal pinout and robust construction, the relay can be swapped into any vehicle that originally shipped with a VEMO or equivalent 30 A fuel pump relay.

Installation Guidance

1. Disconnect the battery: Ensure safety by removing the negative terminal before working on electrical components.
2. Locate the existing relay: It is typically mounted in the engine bay near the fuel pump or within the fuse box.
3. Remove the old relay: Unscrew or unclip the unit, noting its orientation for correct placement.
4. Insert the V15‑71‑0017: Align the pins with the socket and secure it using screws or clips as per the vehicle’s design.
5. Reconnect the battery: Restore power and verify that the fuel pump operates correctly.

For vehicles with a dedicated relay harness, no additional wiring is required. In cases where the original harness differs, a simple adapter can be used to match the 5‑pin configuration of the V15‑71‑0017.

Performance Benefits for the Fuel System

The fuel pump relay is a critical component that ensures the correct timing and duration of electrical pulses sent to the fuel pump. A reliable relay like the V15‑71‑0017 offers:

• Consistent Pulse Delivery: Maintains engine idle stability and prevents stalling.
• Reduced Electrical Noise: High‑quality contacts minimize voltage spikes that could affect other electronic modules.
• Longer Component Life: By protecting the fuel pump from overcurrent, it extends the operational lifespan of both the relay and the pump itself.

Quality Assurance and Compliance

The V15‑71‑0017 is manufactured under strict quality control protocols that meet or exceed OEM specifications. It complies with automotive industry standards for electrical safety, electromagnetic compatibility (EMC), and environmental durability. The relay’s design also adheres to the ISO 9001 certification guidelines, ensuring consistent performance across production batches.

Maintenance Tips

• Inspect the relay housing for cracks or corrosion periodically; replace if any damage is observed.
• Check the connector pins for oxidation; clean with a contact cleaner if necessary.
• Avoid exposing the relay to excessive moisture or oil spills, which can degrade insulation and contacts.
