INPA DSC Brake Bleed

Summary

Guide on how to use INPA to bleed the brake lines

Intro

This is a supplemental process to bleeding your brakes the normal way with a pressure or vacuum bleeder. You'll need to make sure you have plenty of brake fluid, because each procedure tends to drain the fluid reservoir almost completely.

Make sure you have an OBD cable connected to the car and INPA installed.

Bleeding Process

When doing this bleeding process on a Left Hand Drive vehicle which has the DSC unit on the left side, you want to make sure you start with the right rear wheel, then move to the left rear, then front right, then front left. If you have dual piston calipers you may need to bleed that wheel twice, once with each valve open.

Start by opening up INPA and select the chassis that applies to your vehicle. F2 for E9X and Shift+F7 for E8X.

Next, select the chassis option and double click on Dynamic Stability Control on the right. If your cable is plugged in correctly, you'll get an error about versions and language not matching.

If you get another error, your cable is probably not connected properly. Try restarting your computer and make sure the cable is plugged into the car and computer before opening INPA.

Next, hit F6 for Activate.

Then select the DSC rework bleeding option for the wheel you are starting with, in this case Shift+F4 for the Right Rear wheel.

It will then tell you to open the Right Rear bleeder screw, make sure you have a bottle hooked up to this valve or it will be spraying fluid all over the place. I recommend a fairly large bottle because it can easily overflow the small containers that come with vacuum bleeder kits.

Once you've opened the screw about one turn, click OK on INPA.

You'll now get a series of prompts which you must respond to in real time. These prompts can vary, and the messages might differ slightly. Just press the brake down until you can feel it stop and hold it there, then release when it tells you to.

Depending on some factors it will repeat this process a few times. When its done, it will tell you to close the bleeding screw.

Refill the brake fluid reservoir with more fluid, and repeat the process for each wheel.
