I have 3 new air struts. On one of them the rear right one I did a test on them. On star it says they start at 0ma and when u hit start 500ma is the value u should see. I have correct values on all but 1. My brand new rear right dampner valve before I even start test show. 9.60ma. When i run test obviously itll show 509.60ma instead of 500ma even .
anybody know why this is happening and how to fix.

also I'm learning I need to buy these connection boxes to test many other things on my car. I use star go to test or check things and it says to connect socket box. I dont have those yet but will soon unless a fellow member has both they want to part with any specialty tools I'm interested in just fyi
