If you ever do any vanos repair or cam work, then these tools are invaluable. I'm not affiliated at all with BAUM, I used these tools to replace my VANOS unit on my M3 and have not used them since. They are like new condition.

If you are working on VANOs, you will benefit from all of the items. I'll do a combo price as well.
