Hi, I come to share my successful brake bleeding experience using a little cable called BMW INPA K+DCAN USB Interface. It is very cheap only $18! Still can’t believe it… Now I will show you how I bleed BMW E46 brake step by step.

First, I plug BMW INPA K+DCAN diagnostic cable in my laptop, and then connect it to my BMW 325i OBD2 port in the driver’s footwell underneath the dash. If you have older Bimmer, you may need the round black connector. After connect, there is red light.

Next, I start INPA software. I run it on WIN XP don’t know whether it run on other windows or not. Then I turn the ignition on and INPA immediately show battery on and ignition on.
