This was asked today, which we ask users to answer who know the difference between the relays of the sedan versus the touring for testing the fuel pump relay...
- A quick test for fuel pump operation (1)

I've been through several of the best links and I've seen this particular post before. However my car seems to have a different configuration.

Here is is pic of my Relay Panel in the Trunk. Which Relay? I have 3 to chose from. The one in your link appears to be for a Wagon.

But bluebee... you already answered the question in post #2.
Oh, yeah. Heh heh... Thanks for pointing that out! :)
Based on that, here's what I answered in the fuel-pump relay testing thread:
- No voltage at fuel pump connector?? E39 540i
Which relay would be my "fuel pump" relay and do I jump the same pin #s (red arrows) shown in your pic?
Based on your car being a 2001 525i, I would say that your K96 fuel pump relay is behind the glovebox, as already shown in post #22 above, but I'll repeat it here for clarity:
Image

I can't answer the question about jumping the pins, but I would 'assume' so, yet, I could understand your desire to wait for a bit more definitive answer from someone who actually knows the answer.
(PS: I have the same relay in the same location so I will benefit from whatever you iron out so let us know, with pictures, how you fare.)

See also the procedure for opening up the stuff under the glovebox for access to your test leads:

EDIT: While there are three or four diagrams of the relays behind the glovebox in this thread, we could probably use an annotated photo or two from the users, so I hope that bem-ster can snap some for us.

So, that others can benefit from this information, notice a few summary items from this thread:
> Detailed step by step diagnostic DIY ... dead battery ... parasitic current drain

The first is that the BMW spec is 40ma for quiescent current drain:
Image

The second is that BMW intimates the car should be able to sit for about 6 weeks:
Image

Given a good BMW E39 battery:
Image

And, there is a quicker way to pinpoint which circuit is causing the parasitic drain other than waiting 16 minutes after pulling any one fuse (and then doing that over and over and over again):

I'm Sorry i may have missed it somewhere but i didnt see where the turn signal flasher relay was located. If someone could be specific it would be greatly appreciated, Thanks in advance.
 
P1145 engine code : ef3 fuse blown after I replace.Trans in limp mode but has reverse

What's up guys, I'm new to this forum but currently own a 2000 323i four door with 151,000 on it and I'm looking for a little help with regards to this thread. I have the engine light, dsc light, abs, and trans light on. The car has reverse and can switch into gear just seems very sluggish. The engine code is p1145 referring to some selenoid loses circuit? ( that isn't the exact meaning. ) but I have checked the ef3 30 amp fuse and it has bad. I changed the fuse of ef3 started the car and P gear came up and a few seconds later went back to the trans light a ( gear with circle around it ). I checked the ef3 30 amp that I just changed and it again had blown. I NEED SOME HELP GUYS , what selenoid needs replacement and will this take the car out of limp mode.

This a BMW E39 thread, but my google search comes up with another thread where the solenoid that is the throwing a P1145 code is under the drivers seat, and it is part of the fuel system. The DME relay fuse was bad and was replaced, and it resolved his engine code issue, I am not sure if this applies to a BMW 323.

For those troubleshooting the horn, this thread has information about relays and fuses related to that component ...
> E39 (1997 - 2003) > 2002 E39 Horns not working
I have a very challenging problem...

The horns on my 525i are not working. I applied voltage directly to both horns and they worked fine. I also replaced the horn relay under the driver's side dash. I replaced a bad 5A fuse in the glovebox for F38. The fuse in F3 was fine.

After doing all of this the horns still did not work.

I then used a voltmeter to check out F3 and F38. F3 had voltage but F38 did not.

Anyone know why there would be no voltage to F38? Is F38 even used for the horns? I looked at the e39 horn wiring diagram and F38 is not even referenced.

Pull the relay. Then check voltages and grounds on the plug as follows:

pin #4 for 85 on relay -> grounded when horn pad pushed, open circuit when horn pad released
Pin #6 for 86 on relay -> B+ from F38 with ignition switch
pin #3 for 30 on relay -> B+ from F3 (not sure if this circuit is switched by ignition)
pins #2 & #5 for the 87s on relay -> short pin #3 to pin #2 for one horn, then pin #3 to pin #5 for other horn.

With those results the faulty circuit (or relay) will be identified.

EDIT: added image from RealOEM in case terminal identifiers on relay or plug are not legible.

Today, a user troubleshooting weird electrical problems ran into this:
> E39 (1997 - 2003) > Help with electrical issue please
I have a 99 528i with 101k. I took the car in for a new battery. After that I am having major electrical issue. The car drives fine, but the headlights, A/C & heater, radio, windshield wipers, power seats, gauges, horn, and power window won't work now. I don't even know where to start looking. Did anyone else have the same problem? Thanks

2001 525iT...I have gone through this whole thread and I still can't figure out where my Auxiliary fan relay is. My box under the air intake has the salmon and the brown relay, but after reading it doesn't sound like either one is correct. My high speed function on my fan has quit. Low speed works, but at certain points the car is heating up at idle because the high speed is not kicking in while the AC is on.

i wanna know also aux fan relay location.do u have old 3 stage resistor fan?mine is new model.does it matter for relay location??
 
can someone confirm that 2002 models have 50amp fuse for aux fan behind glove box?searched in my car and found nothing(will post pics in situ).bentley and others say that aux fan is secured with 50amp fuse.

It's there...I took the glove box out and then look up behind the metal plate that the fuse box is connected to above the big plug of wires, and with a light you will catch the glimpse of the two fuses. I had to use my monkey fingers and go over the top with the fuse box open to get them out and back in.

You might find what you need in these threads, found by typing /f75 in the bestlinks:

I just received this Fuse Housing from BMW and it appears to be incomplete. Is this the way they come through? BMW told me I would have to locate the connectors in the catalog... Say what?? Does anyone know a source of the connectors?
