My steerling column control module is bad. Can I replace old one w/ used part? on 2005 Audi A6 Quattro

The car would not start at all. There was contact and the brake lights worked. I was informed by my mechanic that the steering column module is bad and the who steering column needs replaced. Can it be replaced with a used steering column or does the part have to be new?

you can use salvaged part but can't be sure of of function or life span. you take a chance.
