another great video. Thanks! I had this trifecta happen 1.5 years ago. Tried sensor but no go. Found a place in Massachusetts via ebay that rebuilt the abs module for $125 total. Resolved my issue and 30k miles later still going strong. Keep the videos coming! Awesome!
Great vid, thanks for sharing. It's important to note that earlier E39 versions (1997 and 1998) use different part numbers. They're 34521182159 front and 34521182160 rear. They really look identical to those you showed here (34526756375 front and ***376 rear), but BMW catalog states those are compatible to later E39's i.e: from 1998 to 2003.
If you hook up INPA and see a "precharge pump" error, then that's almost always the ABS module going bad. I send them out to BBA Reman, they have an eBay listing for right around $100 for the repair service. The turnaround is quick- if you send the module out on a Monday you'll probably have it back to you by Friday. I've had a few modules rebuilt by them and I'm pretty happy with their work.
Hot connection in the module. Must rebuild or replace abs module. All the abs units that ends with a 001 on the Bosch part number seems to break often. The older type part nr ends with 0265 they last a lifetime.both units working on e39 cars.
E39Source ok maybe only on a m5. I'm so happy to see that you love this m5 so much. These in my opinion is the benchmark of bmw true drivers car. I would love to own one of them. 540i 6 still pretty awesome. Love your content
If it's only on warm days it could be the ABS Module, i've heard about it that they changed that, i can't remember the year but on my '97 E39 it's not located in the engine bay so it doesn't get heated up. So i guess you'll be fine with repairing it. Good luck!
Had my drivers side rear sensor go bad about one month ago on my 2000 528it. Took it to a BMW specialist shop where it took 3.5 hours to get the sensor out without breaking the hub.
It's the module. They are sensitive to heat so only driving a few miles wont heat soak the module enough to through a code. Had the same problem with my 540.
You do not have to remove the tires. I just replaced all 4. But you definitely need to use the 5mm. But if u don’t remove the wheels just have a lil more patience and use smaller 3/4 socket set
Mine was the hub relucter ring I replaced the sensor and had the module rebuilt my abs light only comes on when I move the car but goes out if i restart it , the hub had rust inside I tried cleaning it but no luck so I replaced both front hubs they were old it worked for me.
I have a question - my e39 does not show me speed so I have tried to check the ABS sensors. Front left wheel looked pretty fine, without any dirt so I moved to the opposite side and realize that there is no ABS sensor on my front right wheel!? Like... I know how it looked like on the left side, so i thought it should be the same on the right side, however there is missing even the cable which should come from the ''top'' to the black box!!! What should I do?
Hi. I’d appreciate it if can help me with something. I’ve just bought a 2000 BMW 540i and I noticed the speedometer is off. I believe the diff gear ratio might have been changed. How can I recalibrate the speedometer for the real speed? Thank you.
I believe there are final drive ratio options in the preference file for the module. You'd need software like NCS Expert to make these changes. If you're local to San Diego, our shop would be happy to make this coding change for you. Please contact me at ryan@e39source.com if you'd like to get on our schedule. Thanks!
ODOMETER isnt working on my e39 540i.. could this be a start to attempt ? I have been reading on some forums that wheel speed sensors might mess with the odometer
I believe the speedometer and mileage are recorded by the rear left wheel speed sensor. I would want to scan the ABS module and IKE error memories first to get a better idea of the problem.
I had p0500 Changed both rear wheel speed sensors , after changing them , I still have the problem where the speedometer not working along with Gas gage etc .. where should i look now ?
If changing the sensors did not fix the problem, I would be inclined to think that your ABS module is faulty. I would remove it, and send it out for repair. I frequently recommend Module Master for this in Idaho.
These bolts are terrible. The new ones I got from BMW are longer than the original ones although they had the same thread. I cleaned out the hole and the bolt wouldn't go in all the way in the hub so the sensor wasn't flush against the hole and I snapped the bolt trying to remove it. I think maybe I overtightened it trying to get it in but still. Don't know if the same will happen on the other side yet as that old bolt snapped when trying to remove it. I have shortened the bolts now to mitigate further issues when I get the sheared bolts extracted. Screwing around with these bolts has been the most time consuming part, accessing the rear wheel sensor connectors behind the wheel arch lining was pretty easy in the end.
I could not find a follow up :). Can you please state your experience with Modulemaster. This is my 2nd E39 with the same issue. Last time I just ate the whatever price was the electronics rebuild circuit board from Bosch. Problem is it's on back-order now and who knows if they will manufacture it again. No one has it. I'm not paying 3k for the unit with the hardware. Please let me know. Or if you have started dipping into those waters of rebuilding units? :)
@@E39Source OK. It's been decided then. Will take the unit down next week and send it out. Just an FYI. I've never had this happen before, but I'm assuming it's all consequence of the fact that DSC unit is completely down. DME reports loss of communication. So I have a speedo that goes in and out. Car doesn't seem to have lost power, but it will cut off at 5500rpm even if fully warmed up. Also fuel gauge goes a little crazy will drop or increase indicated fuel level within a quarter tank at times.
And theres not Trifecta in my car, just the DSC turns on randomly, and sometimes in D position, when i drive uphill inclination, my gearbox shows “ transfailsafe” i did Scan and theres no issue on my tranny.
@@fernandorochafontesdeolive6637 My problem was with the ABS module. I had it rebuilt, and that fixed everything. Trans fail safe is an automatic transmission problem. You will need to replace or rebuild your transmission.
I'm having the same issue, new sensor and light came back on. I've been told that the problem is the after market speed sensor. Has to be oem bmw or ATE sensor so I have read. What's your opinion?
@@E39Source scanned system and right rear speed sensor out, installed genuine bmw sensor and lights went out, then back on again a few miles later. I just noticed the left rear sensor is not bmw, is it possible that they are not compatible together and that both rear should be genuine bmw?
@@OpenAirAdventure That doesn't sound probably to me. What code is it reporting now that the lights have come back on? Check the connection to make sure that the sensor you just installed didn't come apart or something?
Hello, thinking about buying a E39 that got only the abs-light on. Not ESC or DSC. Could this be the abs-module or is it more probable that it's just a ABS sensor? The cars pretty cheap so if it's more likely to just be a ABS sensor issue it's worth buying and DIYing. Thanks! Also, Great video!
It could be anything. You need to pull the code(s) from the ABS module, and see what it is complaining about. Hopefully it's just a speed sensor or some glitch that can be reset along with the codes, but it could be a module too. Rebuilding a module is about $350.
Okey, sadly I don't have the equipment for checking the codes (will probably but if I buy the car). Might be worth gambling if I could get the price down a bit. Thanks for the reply
I assume your issue was the abs module… Are the VDO speed sensors definitely the same as BMW? I know the BMW ones have Siemens written on them, and VDO is part of Siemens. The price difference is huge, so don’t want to buy BMW if the VDO ones work perfectly! I’ve just fitted “apec” branded sensors and they didn’t help with the abs pulsing. Thank you!
That’s great news. You have just saved me £200 / $275. Thank you. I don’t have any lights on, just abs kicking in just before stopping at low speed, so hoping it’s an aftermarket sensor issue. Thanks again 👍
I recently got the traction and abs lights. Engine power was reduced with the module in and when I took it out I got full power. Had to replace the module for 800 bucks and that fixed the problem for about a month. Now it's come back. Any suggestions? Maybe a wheel speed sensor?
I’m having the same problem with my 2001 bmw 330i all the lights are on and my car goes into limp mode after driving it for a few minutes I replaced all wheel sensors
Yes, I did. Anytime there is an issue with your wheel speed sensors, it deactivates the tire control system since it uses those sensors. Rebuilding the ABS module fixed all of my problems. Replacing the speed sensor did not.
I have this problem on my E38 740i. Sometimes when I hit the brakes hard enough, the brake pedal will litteraly vibrate as I hold it down. After that, the 3 lights come on...wtf?
MercenaryRandoms the vibration is your ABS working to prevent you from locking up your tires (this is usually normal). However there is probably a problem if you are getting the lights and ABS turning on even when you aren't slamming down the brake pedal.
I have a BMW 530i 2001. I'm trying to know what sensor to replace i been checking online to know where to start from but I've gotten no where. The code is P0500 and it says inside In the message center something about transmission speed check/programming failed. The way I'm saying it may not be exact but it's something to this nature
The aux fan shouldn't run because of a bad speed sensor... it's either too hot, or the AC is on. Keep in mind that the fan runs whenever the AC is turned on.
How much do you figure it will cost to rebuild the module? Also.. can you drive without any speed sensors plugged in? I took the car to a mechanic because I had no idea what was going on and they replaced the sensors like you did. They said that will fix the problem. Then after I pay, and see that it doesn't work, they take another look at it and tell me I'm gonna need to pay another $900 for a used module. Told them fuck that, take out your sensors and give me my money back, getting the speedo working again isn't worth $1500. They're telling me the car needs the ABS sensors in or I can't drive it.
The module was about $350 to rebuild. You should not drive with any sensors not plugged in. You could tow it home though and then send out the module for a rebuild. I recommend Module Masters in Idaho for this. It'll come back like new.
E39Source thanks. What will happen if nothing is plugged in? My old ones were plugged in, but weren't even working so I can't imagine there would be a difference. I just wouldn't have ABS right?
Well you could possibly get a tamper light on the instrument cluster, which then makes your car worth nothing as the mileage cannot be confirmed. But if you didn't already get that.... you might be okay. I recommend replacing any faulty wheel speed sensors, and then sending the ABS module out for a rebuild.

I'm not getting any codes from my e46, but the triangle light is on. To avoid cleaning/replacing all sensors, how do you know which is the bad one?
For the light to be on, there must be codes stored in the ABS module, LCM, or instrument cluster. Have you scanned these, or only the engine computer?
