E39 (1997 - 2003)
The BMW 5-Series (E39 chassis) was introduced in the United States as a 1997 model year car and lasted until the 2004 when the E60 chassis was released. The United States saw several variations including the 525i, 528i, 530i and 540i. -- View the E39 Wiki

Picture & amperage & description of every single fuse & relay in the BMW E39

EDIT: Added excellent fuse descriptions from Steve530 from post #4 on 3/3/2012.
EDIT: Added cross references to specific fuse-related posts by QSilver7, RDL, cn90, & JimLev 3/13/2013.
EDIT: Added nice closeup of EF1 to EF5 by tobesscooby 4/6/2013.
EDIT: Added better descriptions for F107 to F114 by rdl on 4/8/2013 (and added fuse amperages for the unknown fuses, again, as per rdl).

Let's see if we can list, describe, locate, and show a photo of every fuse and relay in the BMW E39, so that we all benefit.
Below, (from this quest to locate a parasite), is as far as I've been able to get detailing every single fuse in my 2002 525i.

(Note that F1 to F5 exist in two different locations, just to confuse you, so I'll refer to the ebox ones as EF1 to EF5, and the glovebox ones as F1-F5).

There are SIX fuse box locations in my 2002 BMW 525i E39 (here is a 1997 540i fuse location chart):
  • EF1 to EF5 <= at the back of the ebox under the passenger side cabin air filter housing (5 fuse spots)
  • F1 to F45 <= in the glove compartment top panel (45 fuse spots)
  • F46 to F66 <= directly above the battery (21 fuse spots)
  • F67 to F74 <= don't exist
  • F75 to F76 <= behind the glove compartment (2 fuse spots)
  • F77 to F99 <= don't exist
  • F100 to F106 <= above the battery positive terminal (7 fuse spots)
  • F107 to F114 <= under passenger side front seat carpet (8 fuse spots
IN THE White E-BOX UNDER PASSENGER SIDE CABIN AIR FILTER:
EF1 = 30A, MAF, Cam sensor #1, DME, T-Stat, Evap emission valve (some say it's 30A - DME, Injectors, SMG Hydraulic unit)
EF2 = 30A, Fuel injectors, Both Vanos solenoids, Cam sensor #2, SAS pump electrical valve (some say it's 30A - DME, Idle control valve, Fuel tank ventilation valve, Fuel pump)
EF3 = 20A, Cam sensors, MAF, Crank Sensor, Heated O2 sensors (some say it's 30A, others say 25A - E-box fan, Transmission RPM sensor, CPS, MAF sensor, Fuel pump relay, SAP relay, A/C Compressor relay, Fuel tank leakage diagnostic module, SMG selector lever)
EF4 = 30A, DME (some say it's 30A - Oxygen sensors and oxygen sensor heater circuits)
EF5 = 30A, Unloader relay, power to coils (some say it's 30A - Fuel injector relay)
IMPORTANT: The five EF fuses are NOT labeled! Only the values are labeled, but they are symmetric!
It turns out (later in this thread) that EF1 is the left-most fuse (left being defined by being able to read the MOTOR-SICHERUNGEN (aka "engine security measures") printing on the fuse cover itself).
Note: There is a black or white cap enshrouding the five ebox fuses EF1 to EF5, which needs to be removed as explained by RDL in this thread.

Photo below courtesy of JimLev shows the white cap still in place enshrouding the five ebox fuses:

IN TRUNK BATTERY COMPARTMENT:

F54 = 25A, (empty) M5 Fuel pump
F55 = 20A, (empty) Rear washer, Rear washer pump
F56 = 30A, (On-board monitor), (CD changer), Radio, (Navigation system) [Black540eye adds On-board Monitor, Radio, Video Module, CD Changer, Amplifier, GPS Control Module, GPS Receiver]
F57 = 10A, (Telephone)
F58 = 10A, (On-board monitor), (Telephone), Radio, (Navigation system)
F59 = 20A, (empty) Trailer socket
F60 = 50A, (empty) Elecronic damper control

THESE DO NOT EXIST:
F67 = (does not exist in the E39)
F68 = (does not exist in the E39)
F69 = (does not exist in the E39)
F70 = (does not exist in the E39)
F71 = (does not exist in the E39)
F72 = (does not exist in the E39)
F73 = (does not exist in the E39)
F74 = (does not exist in the E39)

BEHIND GLOVEBOX (look from underneath):
F75 = 50A, Auxiliary fan (red) [QSilver7 says the aux fan is the electric fan in front of the radiator which also goes on when the AC is initiated.][bluebee removal hint]
F76 = 40A, Heater blower (yellow) [cn90 says it should have 12V when HVAC is turned on][QSilver7 says the heater blower controls the air velocity for the cabin/interior HVAC system.]

Neither of these huge fuses is easy to remove or put back (due to the cramped location), but luckily the yellow one is the one aft, which is easier than the red to remove.

F101 = 80A, Power supply for fuses F46-F50 and F66

F103 = 50A, Open
F104 = 50A, Unloader relay terminal 15
F105 = 100A [JimLev says F20 and F105 power relay K201, which itself gets power from F75] (rdl says his F105 is 100A)
F106 = 100A, F75, Engine cooling fan relay stage 3


UNDER PASSENGER SEAT: (see more details in this thread & this thread)
F107 = 50A, SAS airpump Special Fuse: BMW PN 6113836590 (rdl says it's the secondary air relay fuse)
F108 = 50A, [QSilver7 says this is for the ABS/DSC control unit] (rdl says it's the "motor relay") (rdl clarifies that the F108 "motor relay" fuse supplies ASC or DSC) (rdl says his F108 is 50A)
F109 = 80A, [QSilver7 says this is for the DME (motor electronics)] (rdl says it fuses the Ebox EF1 and the DME relay in the ebox) (rdl says his F109 is 80A)
F110 = 80A, Power supply F1-F12 and F22-F26 (rdl says this fuses about 17 fuses, up to F45) found in the glovebox)
F111 = 50A, Data link connector/ Ignition switch (rdl confirms this is the ignition switch fuse)
F112 = 80A, Light control module (rdl confirms this is the LCM fuse)
F113 = 80A, Power supply F13 and F27-F30/ Light Module (rdl says it fuses the LCM and several fuses in glovebox plus in some cars a "closed-circuit current cutout relay" which then feeds a fuse in glovebox)
F114 = 50A, Data link connector/ Ignition switch (rdl confirms this is for the ignition switch and diagnostic plug)


In addition, there is a 10A fuse on the back of the Radio/MID as per cn90 over here:
