BMW E-Box, 3 Series E46 Engine Computer, Engine Fuse Locations, Engine Main Relay Wiper Relay

This video shows you how to access the components in the E-Box also known as the electronics box. This area contains the engine computer known as the DME (Digital Motor Electronics Module) as well as important engine fuses. The DME engine computer main relay and injector relay are also in the E-box. This is also the location of the wiper relay which I also demonstrate the location of. I also go over some troubleshooting tips for an odd failure I have seen for the throttle.

Hi and Thank you very much for taking the time to share this. I'm experiencing some issues with my throttle and after watching your video I decided to check the fuses. After removing the box holding the 5 fuses I found that the first 30A is not connected to anything (which i figure may be a redundant slot used in another model). However the 20A fuse in the middle is a mystery to me as it only has contact on one of its blades. Unfortunately I don't have access to the wiring schematic for my car so cant check if thats normal. (sorry for the long intro) my question is could you confirm if that's normal?? the car is a 2000 e46 sedan with the M43 engine.

Thanks for the great video.I got the same bmw model as in youre video and i have one problem with starting up the engine. When i turn key to start the engine on second position all panel lights start to blink. I wonder it can be the battery, but later i remove the old battery and install a new one, but same blinks every time i want tostart the engine. Later i discover some sound in the fuse box under the hood it was the blue relay which was giving out this sound while i've tryed to start the engine. I pull out the blue relay inspect, but looks that it not have burning spots on it or something else. I'm bit confused now, maybe some help from you. Thanks a lot.

you are the sharpest guy i have found yet. I have a 2001 325i that will not crank when it get below 32 or so. Warms back up outside and it cranks and runs fine. I am suspect that there is water somewhere in the ebox. Do you have any ideas? I can hear that the fuel pump is not engaging when this problem occurs. There is a cold front moving and i would really like to solve this problem.

[@LouStaniforth]

Thanks pal my glow plugs were not starting up on cold start turns out it was a fuse in the engine fuse box cheers

Awesome video mate.... I was looking for the fuse for head light.... it’s not in the glove compartment ,, do you know where it is? I have change the bulb but still not working... pls help

[@eugenebruno1481]

Hey, I just watched your video--which is very informative. I just learned something new. I have a problem, I purchased my 2003 BMW 325I (manual) 2yrs ago and it drove ok. But I have realized they hardly kept up with maintenance. But my problem is, my BMW does not drive like a BMW. It does not accelerate with power when I step on the gas; it feels like it struggles to move, like it drags. Basically, it does not move with power like BMW's are supposed to. What you guys know what is wrong with my BMW?

[@ramongambino1977]

great video , I'm having starting issues . I replaced the alternator, battery , coil packs , spark plugs . I went to turn it on , radio and dash board lights went haywire . Please help ?

[@RcLento]

Exellent,great job,really good explanation,well done

[@casey7616]

Great videos man!

[@DJzSith]

GREAT TIP!

[@fanyang7146]

what's that green relay? Not for A/C? my A/C blower motor stop work, I checked all the fuses in glove box and replaced FSU as well, but still not work. and I take off Blower motor to check if the motor does not work, but the motor works good, and I use voltage meter to check blower connector, this is no voltage in connector, so next step I wanna find if the relay is bad or take off the HVAC control unit to check maybe some wire is disconnected or the HVAC control unit is bad.

[@marcvidot8152]

So I replaced my water pump and radioator and battery all at once and now my 05 325ci is stuck in limp mode could it possible be a ecu fuse issue .. plz help 🙏🏽🙏🏽

[@josuegonzalez9364]

I watched this video and I took off my ecm to check for oil or any water damage and my car went to eml mode and now it revs on its on unable to drive it any help please ??

[@AskTheCarExperts]

Hello Josue, What happened is that your throttle lost calibration. Do the following...without starting put the key in the ignition and cycle the key on to the second position. All cluster lights come on. Wait 5 seconds and shut if off. Repeat again. This will calibrate your throttle. Then start normally. If the problem still occurs check your connections again at your DME and retry. Please remember to subscribe, Thanks! Let me know how you make out.

[@josuegonzalez9364]
