Role of the ECU Fuel Pump Relay in Audi Vehicles

The ECU fuel pump relay in Audi A4 B7, A6 C6, and Q7 4L models is responsible for controlling the fuel pump power supply according to signals from the engine control unit. A correctly functioning component:

• ensures controlled activation and deactivation of the fuel pump,
• stabilizes the power supply system during startup and while driving,
• supports correct fuel metering by the ECU.

Thanks to this, the injection system operates under conditions foreseen by the manufacturer, and the engine retains its factory performance parameters.
