Light malfunction
 

One day my car all the sudden indicated that none of the rear lights were working and to visit the shop. Has anyone had a similar issue?

Looks like they fixed it after a week in the shop by doing a software update.

I had a center / third brake light fault at about 300 miles. They tested with the light housing form another A6 and it fixed the problem, so apparently there was something wrong in the light fixture itself on mine.

Had a light fault first day with car. Supposedly did a s.w. update. Hasn't happened since.
