Only after joining up to the site. After picking up a 2013 a6 s line auto. Unfortunately I've noticed an issue with the dome light. When the car is unlocked the light come on front and back as it should. Unfortunately once the ignition is switched on the light seems to loose power. The buttons won't illuminate and none of the lights work. The sun visor lights work fine but not the dome one. Once I open s door the light comes on just fine. Is this a common issue with them or an unusual problem?
