- Fixing ABS Issues in E39 BMW: A Step-by-Step Guide
Are you experiencing issues with the ABS in your E39 BMW? The ABS warning light is flashing, and you're not sure what's causing the problem? If so, you're in the right place. In this article, we'll show you how to diagnose the issues associated with ABS and how to fix them.
The ABS warning light should come on and flash when you turn the ignition on, and then it should turn off. However, if the light doesn't come on every time, that's a sign of a particular issue. You may also notice that your traction light is on, which means it's switched off.
To diagnose the problem, you need to know which ABS module you have. There are two types of ABS modules in the E39. The first one is located inside the car, which is the better one. The second one is located in the engine bay, and it causes more problems because of the heat from the exhaust manifold.
The first thing you should do is check which module you have. If you have the later E39, your ABS module will be located in the engine bay. If you have the earlier one, it's located behind the glove box.
To access the ABS module, you don't have to take the glove box off. There's a beige tray that slides out underneath the glove box, and the ABS module is located roughly around there. Once you have access to the module, you can test your ABS sensors and other issues without having to take every single wheel off.
The tests you can run include resistance voltage, diode test, and earth test. You can also test the ABS sensors from the ABS module. These tests will help you diagnose the issues with your ABS and fix them.
In conclusion, fixing ABS issues in your E39 BMW can be challenging, but with our step-by-step guide, you can diagnose the issues and fix them yourself. Don't worry if your ABS system is not identical to the one in the video. You can still run the tests from the ABS module and fix the issues. If you follow the instructions carefully, you can save a lot of money on mechanic bills. Don't forget to subscribe to our channel for more helpful videos. - Авто та транспорт

Was there every a video showing how to test it? I looked thru your page but did not see it
thanks for the reply, monday i am planning to send it to my mechanic to start the diagnostics, the last time we hooked it up to a computer it gave : 104 - angle sensor for steerring wheel not functional.
I can't find part 2!!! are you able to provide??? thanks!!!
Mine looks similar but not exactly the same. There's a unit in the same spot, but not identical and one of the connectors on the back is different, therefore I'm not sure if it's the later version or not. It's a 2001 530i. My ABS light has been coming on lately, and just today actually activated and braked a couple times, which freaked me out.
I worked at BMW sometimes it's as easy as changing a fuse and the cheapest option :)
Guys what is the ASC means? is it the same as the ABS?
Steering wheel sensor will throw DSC out of function and costs a bit to replace, located around steering column and works with understeer etc so could be your problem as all parts related to traction, Abs ETC
Hi can not find the 2nd video can i get a link please
HI NICE VIDEO IS READY THE PART TWO OF THE VIDEO SEND US THE LINK THX
My friend i have e39 520i e39 1996....asc isnt working abs does work....the abs isnt lightning at all ....scan code says abs asc module ? Any ideas
hi i have the same problem i drove under torrential rain and know my 5 series bmw doesnt accept to drave on full power,it runs slow and the DSC light is always on.the displays says:"engine fail safe program"Can you help to figure it up?
Hey mate ASC light on 24/7 own 2000 model e39 shape can u please just tell me how to diagnose myself cheers
Yes you need to invest some INPA diagnostic software or similar, very cheap, you have some issues there and an error/fault code reading is your solution there...thats where to start...good luck!...once you have codes post on a forum like bimmerforums and you should get it resolved and handled.
hi! i have a problem in my x5 2002, my abs does not seem to work, my esp button does not function, my downhill button does not function. and also i think my 4wd does not work too! the weird thing though is that the lamp indicators for abs,esp,4wd do NOT light at ALL! totally dead! any suggestions?
hi how are you? i am from AUS. My 2003 E39 530i has the ASC light stay on all the time, just the ASC light only. But i replace the new ABS Module 18 months ago, why now the ASC light on again? need help.
Can't find the second video! :(
Will be uploaded soon, waiting for the torrential rain to pass, if you have any question regarding this traction light fault, do ask.
Yoooo! Where is the second video? Lol
My car has a no communication error between the abs and the SAS and DME. Can connect to all of the modules individually, but they can't communicate with each other
I have. 1997 bmw 540i and I have the traction control light on and abs light on and my speedometer doesn't work I'm trying to figure out if I can just swap a different abs module from another car without coding it....my module is inside
have you checked the wheel speed sensors in regards to the speedometer??
'bulletsilver75'.....Well you will need to get a diagnostic scan for sure 100%, as you have clearly got something soaking and its failed and hence your car is in limp mode, there is no other way other than to have it scanned as a sensor or similar is buggered.
No next video.. or at least I can’t find it?
Same here...
There is no part two
You never posted the
Follow up 😭
Nettoyez les capteur avant et c'est bon
where is the next video? :-)
Its a pain in the balls.....im fabricating a heat shield extension.
hello my abs light is still on after i replace it now my speedometer dont work. what can i do
Если спидометр не работает надо заменить датчик абс на левом колёсах
there is a company on ebay that rebuilds the module for $95 (vs $1,100 at shop for new, install, and coding), no recoding required either. Anybody have experience with that?
