Irishman

Hi all I am a new member. I have had several Audi vehicles over the years great cars. Just purchased a 2010 q7 . Noticed left hand front led turn signal with moisture in it . Later in the week the light out symbol came on . I checked and the led was out on the front . The rear was working. I removed the right hand front and plugged it into the left side to check the wiring to the left signal . I have no power to the left turn signal . I also checked the left turn signal it doesn't work. Are there any fusible links , or fuses for that circuit. I guess I need a turn signal assembly, but I need some help with tracing the wiring. Any help would be appreciated thanks .
