I have a right rear fog light failure as displayed on the dashboard, rest of the cluster is working fine along with the left fog light They're LED lights I'm guessing no bulb failure. Is there a fuse that supports the light, I can't find one in the manual. I can't get car through MOT until problem is fixed, chap at Halfords who were doing the MOT ran his laptop and picked up the error. Any ideas on this problem before I take it to an Audi specialist. Thanks in advance for any guidance
