How to Install a Fuel Pump Relay on a 2002 Audi A4


1. Place the vehicle's transmission in "Park" and turn on the interior lighting. Apply the emergency brake.
2. Look underneath the dashboard and find the fuel pump relay--it’s located next to the steering column, above the pedals.
3. Unplug the fuel pump relay from its connector and discard it. Install the replacement relay.
4. Turn the key to the “On” position and listen as the fuel pump energizes for a 2 to 3 second period. If the fuel pump energizes, then the relay is functioning properly.
