Horn Assembly problems of the 2009 Volkswagen CC

Issue happened after incident in August 2011 and progressively became worse. Steering wheel will lose electrical power to controls (I. E. Stereo controls) and causes airbag warning light to come on and horn will not function at all. Dealer looked into issue and found that the clockspring needed replacement. Clockspring replaced in steering wheel and airbag issue has been resolved but steering wheel control issue still remains along with not having a working horn. Vw USA had no known fix for this issue as al wiring is in working order. Dealership requested vehicle be brought back in for a further look.
