Fuses & Circuit Breakers - E39: Other BMW 5 series E39 facelift

Power Supply (Fuse Box)

The power distribution box for the E39 and E53 is inside the vehicle.

Scheme 1

The main fuse box is located inside the glove box above a hinged panel.

A "pull out" fuse designation card is also located in the fuse box. This notes

1. Fuse value in amps
2. Location
3. Circuit listing by fuse

Scheme 2

The placement of the power distribution box is close to the main electronics carrier behind the glove box. The modules/relays located in the electronics carrier are dependent upon model, year and optional equipment. Examples of these modules include

1. General Module III (GM III)
2. Drive away protection (EWS II)
3. Anti-lock Brake (ABS/ASC+ T and early DSC 5.3 up to 99 MY)
4. Light Check Module (LCM) - behind right kick panel
5. Overload protection relay module
6. LWR Module

Some of the relays found behind the glove box include

1. K4 Blower Relay
2. K9 Unloader Relay
3. K72 Closed Circuit Cut-off Relay
4. K131 Visual Entry Aid Relay

Fuse Box (Power Distribution Centers)

The E39 and E53 utilize high amperage fused power distribution centers.

Scheme 4

The E39 location is found under the carpet on the passenger's side floor in the sill area and in the right rear area of the trunk, forward of the battery.

The X5 utilizes a single high amperage fused power distribution center located next to the left side EHC air reservoir beneath the cargo area floor paneling.

Scheme 5

An auxiliary fuse box is located in the trunk above the battery. In addition to fuses, the auxiliary fuse box also contains relays (examples)

1. Fuel filler flap lock motor relay
2. Fuel pump relay (some vehicles)
3. Rear defroster relay
4. Unloader relay

Fuses For Engine Electronics

Located in the E-Box, a small fuse carrier contains 5 fuses for engine electronics. These fuses are designated F1 through F5. These are not to be confused with the fuses for the body electronics systems which use the same numerical designation (F1-F5).

Scheme 7

These fuses supply power to systems related to engine electronics such as

1. Fuel Injectors
2. Engine Control Module (DME)
3. Transmission Control Module EGS)
4. Heated Oxygen Sensors
5. VANOS Solenoids
6. Camshaft Sensors
7. Hot-Film Air Mass Meter
8. Electronically (Map) Controlled Thermostat
