Greetings

The problem is, that the onboard computer panel lights do not react at all (they dont lit up) when pressing the button. Also the check light in the dashboard is lit up all the time. What I've noticed though is that when I turn on/off the front lights (pulling the lever out and pushing it back in), some lights in the panel react aka they flicker just for a moment.

As I've removed the floormat and the bottom cover of the steeringwheel, it's the best time to check any wires that might cause the problem. So please give some advice what might cause this issue since I have no clue about electronics.

Best regards

From that thread I read that the cluster computer? could be faulty, because I did have a problem with the tachometre, which sometimes works and sometimes not.

Just to make clear, my BMW is a preface 320 and thatfor many of the topics about electronical problems can't be associated with my car. Correct me if I'm wrong.

It may well be a bad main circuit board in the cluster.

So should I first try changing the whole instrument cluster together with the circuit board and see if there's any changes? If that's faulty, does it reall affect the computer panel lights near the rear view mirror?

I think I'd start with that.

I second that same notion from witeshark.
