Problem with the steering wheel of an Audi A4

How to focus the wheel of the steering wheel of an Audi A4 airvag from 96, the steering wheel is second -hand in perfect condition only the owner does not know if they were disassembled with the centered steering wheel or if they turned to the reel, I do not commit to mount it in the car for fear of Ke reaches the top and breaks, if any way to know?

You turn the reel with your hand and tell the turns until it gets to the top, of the total turns tours half of the laps in the opposite direction and place the straight steering wheel.

What a good Manell 19 data, that is a not very well known trick, and I haven't seen him again.
