BMW E39 ABS and ASC Fault - How To Fix

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.
