C6 S6 gauge cluster is illuminated when the car is off

Strangest thing that just started happening, when I park and lock my car all the usual things happen (beeps, lights flash, lights shut off). But shortly after the gauge cluster (and only the gauge cluster, nothing else) illuminates, and stays lit until I come back to the car and open the door.

Anyone ever hear of this happening?

Do you have a vag com. This can happen due to a bad door switch or the starter switch can be registering a fault.

Try next time leaving he raido on and then do the same thing.

After you come back and open the door will the dash turn off…

The gauge lighting does turn off as soon as I put my hand near the door handle and it Auto Unlock’s. Curious if it’s a faulty door switch, every once in a while the alarm will trigger for no reason.

I usually have the radio on when I shut the car off but then it turns off when I open the door.

I do have a vag com

With the vag com check the body control module. That should tell you if there is any codes for the door switch. You can also open up the body module and have the vag com plugged in when you key off the car. If I’m not mistaken the body module will still talk to vag com with the car keyed off. If that is the case you can log and see what module is still active.

Old thread revival … Did this ever get fixed ? I’m having the same issue. Dash backlight coming on about 30 seconds after locking the car. Saw it one evening and now know this is what has killed my old battery.
