Product Description
The QUINTON HAZELL Fuel Pump Relay (XRL101) is an automotive-grade electrical switching module designed to manage the high-current demands of electric fuel pumps. In most vehicle electrical architectures, a fuel pump consumes significantly more amperage than standard lighting or sensor circuits. This relay acts as an intermediary, allowing a low-current signal from the Engine Control Unit (ECU) to safely activate the higher-current circuit required to drive the fuel pump motor. Its construction features a high-conductivity internal coil and robust contact surfaces, ensuring reliable power delivery and preventing voltage drops that could lead to erratic fuel delivery or "no-start" conditions.

General Compatibility
Because the XRL101 utilizes the widely adopted standard VAG (Volkswagen Group) relay pin configuration, it is compatible with a vast array of vehicles across several decades. It serves as a universal replacement for many "4-pin" relays in the VAG ecosystem:
| Make | Application Context |
|---|---|
| Volkswagen | Golf, Polo, Passat, Transporter, Caddy (1990s–2010s) |
| Audi | A3, A4, A6, TT (1995–2015) |
| Seat / Skoda | Ibiza, Leon, Fabia, Octavia (Common relay block positions) |
⚠️ Diagnostic & Installation Guidelines:
- Confirming Fitment: Before installation, you must compare the pin configuration of the XRL101 with your original unit. While the pin layout is standard for VAG, some positions require a 5-pin relay (which includes a "normally closed" contact). The XRL101 is a 4-pin "normally open" relay. If your original unit has 5 pins, this relay will not function correctly.
- Check the Socket: If your original relay failed, inspect the fuse box socket for signs of overheating or "arc marks" (blackened plastic or metal). If the terminals are loose or corroded, installing a new relay will not solve the issue; you must clean the terminals with electrical contact cleaner to ensure a tight connection.
- Verify the Fault: If the vehicle still fails to start after replacing the relay, ensure you hear an audible "click" when the ignition is turned to the "ON" position. If there is no click, the issue may be the ignition switch or the ECU signal, rather than the relay itself.
