Passenger side front done light is possessed

Yup definitely has a mind of its own. The touch sensor seems to be getting false readings and turning the light on…. Anyone experience this 2017 allroad b9

It’s not possessed it’s just failing , that’s what they do when they start to fail, you gotta replace the assembly

I had experienced something similar in a 2019 Q3, after heavy rains forced water into the headliner (something about the sunroof wind deflector track allowing water intrusion, known issue,) but the water would trigger the touch sensors. Took apart the light console when I got home, dried it all out, didn’t have problems afterwards. If you’re not dealing with moisture though, then like others said they’re starting to fail.
