Hi everyone

New member - just bought 2003 A6 Avant 2.5 TDI SE

Problem is that my interior lights keep pulsing on for a few seconds, not all the time, but just every three or four minutes after the doors are shut and the lights have switched off, they keep pulsing on and off

I've started just switching themm to "off" at the main switch in the rooflight, but it 's not ideal

Any ideas what it might be?

Is there an elctronic gizmo that delays the switchoff that mnight be failing?

Hi Jasper. Im not sure if this is the same problem as i was getting with my Audi A4 2002 but it sounds similar. Is it just the interior light's that pulsate? A photo would be ideal so i know if the A6 has the same light cluster/unit that the A4 has. My problem was down to the light console in the front roof lining. The lights not really pulsate but more flashed a few times to the point where it ended up blowing a fuse. I removed the unit and there's a plastic insert that holds the blubs in place that the wiring connects too. This plastic insert had come loose which i think was causing a bad earth. I refitted it all correctly, replaced the fuse and now the lights work as they should. Worth a shot and keep us all updated if you find a fix for this problem.
