Is there a common reason my cluster lights would turn on with the headlights but then turn off again after a couple of seconds like I flipped a switch?

I haven't checked anything yet I'm just hoping there's something specific that might cause the problem, I don't want to have to go chasing all the connections to find a bad ground or something like that because I don't have a wiring diagram or the patience for elecronics

I imagine there is a chance it's a voltage issue, the car hadn't run in about 4 years when I bought it and I haven't put a new battery in it yet but I doubt it because the issue doesn't go away when the car is running

It's a 96 850 TDI with the 'CD' trim level if that makes any difference
