Hi I have a 2010 Audi S5 convertible. The front both seats do not work. The heated seat function works, the lumbar adjustment worked for a bit and stopped too. The driver side made a click noise before when I tried moving seat and doesn’t even do that anymore and the lumbar adjustment doesn’t work either. The passenger side has same thing. The light on the back seat foot area works too just the power to adjust movent doesn’t work. Just checked every fuse in the car and everything is good. Don’t know what to do. Don’t think it’s the motors because can’t imagine all of them failing. Could be the modules maybe. What do you guys think?
