This question was asked again today, which was also asked a few times in this thread (where one person said to not bother to pull the cover off as the fuses can be accessed from the underside)...

All of the following is gleaned from BMW WDS, and is valid for cars with DME motor electronics MS43 and left-hand drive only.

EDIT - Fuses 1-5 = Bluebee's fuses EF1-5

Fuse 1 connects to the DME relay (DME box), Fuse 31 (glove box), and all 6 ignition coils.

Fuses 2, 3, and 4 all connect to the DME relay.

Fuse 2 also connects to the DME itself, along with the idle control valve, charcoal filter valve, VANOS inlet and exhaust valves, DISA valve, and SAS pump valve.

Fuse 3 also connects to the two camshaft position sensors, the MAF, crankshaft position sensor, and the thermostat.

Fuse 4 also connects to the 4 oxygen sensors, and the transmission control unit (automatics only, obviously).

Fuse 5 connects to Fuse 109 (under the passenger-side carpet), and the fuel injector relay (DME box).

The fuses are read left to right, just like the words "Motor-Sicherungen" -- which by the way translates from German to "engine security measures." Given the components that these fuses connect to, it's aptly named

Thanks for adding detail on those elusive fuses.
Just to reiterate for those not reading the whole thread, BMW calls them Fuse 1 through Fuse 5, but we already have another set of fuses that BMW calls Fuse 1 to Fuse 5, so, that's why I specifically label them here as Engine Fuse 1 through Engine Fuse 5.

Thanks for confirming that information, since, to my knowledge, while it's logical, nobody had confirmed that before.

We'll go with Fuse 1 being on the left, and Fuse 5 being on the right, and read the same way as the words stamped on the cover plate. Thanks for pitching in!

Argh, there are only 5

Apparently I can't count, if it's past 2AM. Also, I didn't know I was late to the party, but that's what I get for not reading the whole thread

Thanks for noticing that I followed up on your 6 with 6 which I have subsequently fixed back to 5 (we both made the exact same mistake, even though we both knew it was 5).

Anyway, I just came here to update the thread on Fuse 53 (F53) information which was just posted today over here...

S167 rear lid lock switch is a component of the trunk lock cylinder in the rear lid. If memory serves, the switch that puts the car in valet mode when the lock is turned fully clockwise, i.e. horizontal. It is not the switch on the A-post near the driver's door nor the release switch over the licence plate.

The relays in the Touring schematic are for the rear lid/liftgate and rear window releases; not the optional automatic/power opening system.

This thread, while confusing, was updated today, and shows a complex situation related to the DME fuses, that others may benefit from...

..also contains this wire color cross reference, I think if hand-wiring an O2 sensor, not sure if correct..
Info compliments of Dale Burdette.

Added the O2 sensor wire colors to the following print.

F1 open (no fuse)
F2 30 Amps, Fuel injectors, Engine control module
F3 20 Amps, Cam sensors, MAF, Crank Sensor, Thermostat
F4 30 Amps, Heated O2 sensors, Tranny control module
F5 30 Amps, Unloader relay, power to coils

Here is what my 2000 540/6 really has. (might be more that below, this is what I could trace out)
F1 30 Amps, MAF, Cam sensor #1, DME, T-Stat, Evap emission valve
F2 30 Amps, Fuel injectors, Both Vanos solenoids, Cam sensor #2, Secondary air injection pump electrical valve.
F3 30 Amps, Cam sensors, MAF, Crank Sensor, Heated O2 sensors.
F4 30 Amps, DME
F5 30 Amps, Unloader relay, power to coils

update - There is a 20A fuse in F3 and that was blown, so not like either of above. Replaced, clear codes, fuel loop working again. The fuse box is hard to work with, poor design IMO. First need to bend long plastic tab and lift the bezel up just enough so it doesn't reclip, then I needed needle nose pliers to grab the bezel and wiggle the fuse module up and out. Then to get the bezel off there's good photos here:
http://blog.bavauto.com/5677/bmw-e46...derhood-e-box/

..but I slid it off by prying sideways underneath. Inspected but really didn't see the actual tab or mechanism keeping it from sliding.

Also your husband will eventually get sick of tearing into the car to get to the fuse.

Still missing fuse # and location

As great is this post is I still cannot locate the rear door actuator fuse # My doors will not unlock with key. Thanks

I don't, offhand, know which fuse is for the "rear door actuator", but, all I did was look at post #1 and type /door f3, and this came up instantly:
Pressing the F3 key a few times only came up with the fuel door solenoid fuse, so, if you asked me, pure logic dictates I'd say it was F6, just like it says in the first post.
Clicking on the linked text brings up this, which seems to bolster that assumption.

Try checking the fuse again &/or simply replacing it. Although rare, occasionally a fuse faults without a easily visible break in the link. Also check the terminals in the fuse block haven't pushed back/out, i.e. fuse actually enters the terminals.

The fuse 6 circuit enters the door via connector X256 pin 26. X256 is the one in the rubber boot at the A pillar to front of door. Should be 12V with key on.

If the fuse and X256 check out, check for 12 V on pin #1 of X889, the black 5 pin connector to the door module. Key on.

Grounding is via a block at bottom front of door and then pin 27 of X256. But since door light works this should be OK. Only a faint possibility of high resistance that allows light to work but not the window or lock motors.

Having the socket for F6 backed out (thus effectively breaking that circuit) caused me absolutely no other issues besides loss of window and lock functions on the front passenger door.
After I followed his guidance and corrected the loose socket and reinstalled the fuse, my problem was rectified.

Fuse F6 most certainly supplies the power to the FR door module and nothing else.

My problem and resolution most certainly confirm that.
Of course, it's well known that lots of key-lock-related anomalies are due to the frayed trunk wiring loom:

Thanks for all the work that went into this but I think the person that said many of these things vary by year and manuf date had it right. I, for one, have a 4/1/02 e39 m5 in which I cannot locate the 8 pin fuel pump relay. Your pic of a 2001 shows it being behind the glove box but alas the pic looks nothing like what I am seeing. I tried RealOEM.com (a great resource I might add!) and while it has a picture of almost every relay's location the fuel pump relay shows only a schematic. Any help would sure be better than where I am now!

Undocumented starter relay

Long time lurker, new member, figured this was a good thread to start a new post.

I'm finishing up a 6 speed swap in my 01/1997 540 and have been unable to find any accurate starter relay location. It's not under the dash behind the glove box as is documented most places (including the WDS) so I traced back pin 1 off the EWS and found it. Pics and diagram below. The relay is in the ebox behind the DME. There is a bank of 3 relays and a fuse holder for the dme. 2 on the left, one on the right. Starter relay is at the far left.

This is originally an 01/1997 540iA and I'll be bypassing the dme and using the switched 12v off ignition pin 8 to feed the relay at pin 8 (85), and grounding pin 4 (86) which originally is a switched ground from the DME. Disconnecting the switched ground and using ignition leaves the relay in place but greatly simplifies the wiring involved.. This will basically reverse the relay to be switched from the ignition at pole 85 instead of the dme at pole 86.

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:

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
F102 = 80A, Power supply for fuses F51-F55 [wiring diagram here]
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:
I dot find fuse for park assistant.
It's not working now for some reason

Excellent stuff! I don't have diagnostics and mechanic until at least Saturday. Does anybody have the most common causes on an E39 540i for a parasitic battery drain has I will have to do this manually trial & error to see if I can make any headway and maybe get lucky between now and Saturday?
TIA

Fantastic job BlueBee! Thanks for your contribution. Electrical is not my strongest area so I am waiting on my mechanic (and this New England weather)

I wonder if you know what is responsible for what I believe is my e39 540i not going to sleep based on the lighted "P" on the shift gate doesn't go off after 16 minutes but yet instead blinks once every so often? What is this most commonly caused by?

Thanks.

Bluebee I/we cannot thank you enough for the many contributions you've given us here.
You've saved us from countless hours of looking for fuses and relays. I simply cannot thank you and the other great contributors enough.

Cheers

A couple of (hopefully) helpful comments and a question or two:

* I think the figure below "ABOVE BATTERY POSITIVE TERMINAL" in post #1 needs to be modified. The arrows should all be shifted to the left by one location. In the text, the fuse denoted as F100 is listed as a 200A fuse. Clearly, the only 200A fuse in the figure is at the far left (inboard) position, not the second from left. Similarly for the fuse denoted F105 at 100A. It is clearly the sixth fuse from the left in the figure, not the seventh as indicated in the figure currently. Note that there are a total of eight positions, but, as here, the Bentley manual only labels seven of them (F100 through F106), but the Bentley manual starts at the far left position, not the second from the left, so in the Bentley it's the position on the far right that has no label. In my case, this position has a fuse in place, but there's nothing connected to it. Note also that the only labeling scheme on the car itself for these fuses numbers them from "1" to "8", starting at the right or outboard position. So F100 correspond to "8" and F105 corresponds to "3".
* While maybe it's already clear to everyone, there are at least two types of covers for the under-hood electronics box, one without hinges (as on my '99 528i) and one with hinges (as on my '03 530i, and as pointed out by one of the more recent posters).

Which leads me to my question. The reason I was looking into this was to track down a parasitic current draw on my '99 528i. In the end, I found that the load in question went through F105, which supposedly powers relay K201, which in turn powers the auxiliary fan. According to Bentley, and everything else I've been able to find, K201 is inside the under-hood electronics box, but this isn't the case on my car. There are exactly four relays in the box, which I believe are an unloader relay, wiper relay, fuel injector relay, and secondary air pump relay. In any case, pulling all four relays had no effect whatsoever on the current draw. In the end, I temporarily solved the current draw issue by unplugging the connector to the auxiliary fan itself. I would like to be able to locate the K201 relay so that I can tell if the problem lies with the relay or with the fan. Anyone have any suggestions on where to locate it?

-Doug

It's funny cause sometimes I read her threads, including her last one and think the same thing.
