How to Locate a 2002 BMW E46 Fuel Pump Relay

Locating and Removing
1. Open the glove box and remove the six glove-box-retaining screws — three across the top, one on either side and one on the bottom corner of the passenger’s side — with a Phillips screwdriver. Pull the glove box outward and down to remove it. Allow the glove box to set on the floor.
2. Look just above the white storage unit behind the glove box and find the two leftmost wiring harnesses. Unplug these two harnesses by pressing and holding the locking button on each, while pulling the harness toward you. Once you unplug the wiring harnesses, notice the three relays above the white storage unit.
3. Grab the leftmost relay — the fuel pump relay — and pull it outward with a slight wiggling motion to remove it.
Installation
4. Line up the prongs on the new fuel pump relay with the slots in the receptacle. Press the relay into the receptacle.
5. Plug the two wiring harnesses back into their respective receptacles.
6. Set the glove box back in its cavity in the dashboard. Tighten the six glove box retaining screws with a Phillips screwdriver.
