You can review this video by AGA for usage. I advise to review as many videos as you can before tackling the project. I spent almost a whole month reading and reviewing about the project. I didn't want to leave anything to chance and end up messing up my X5 instead of fixing it. But that's just me as I tend to be slow but thorough and sure in my DIY projects.
