my warning lights are coming on and off, flickering and times. How can I trouble shoot this. Do I have buy a new one or is it a wiring problem

 

I have the EXACT same problem. I do not know what it is, but people have suggested that it could be cold solder joints. I've been told to tear apart my dash and re-do all the wiring connections and that should help. I just haven't gotten around to trying that yet. Let me know if you find out any other information as well.

All the lights in the warning cluster are lighting up and flashing at random times? It's probably a sign that your alternator is going out or the alt belt needs to be replaced. Could also be cold solder joints.

 

this is a very common problem especially with S4's. Most likely solder joints. I just get used to it. I know when im turning really hard when my whiper fluid light comes on

 

My Fc did that a while back, turned out it was the alt, going bad.

I swapped/upgraded to a FD alt.
