I know on my hatch I had the issue of no restart after driving and it was the main relay. I pulled it out and resoldered the contacts. Works like a charm now. (I used to get stuck at the gas station almost every morning on the way to work, lol) That will cause the code 16.

As for the cluster lights flashing, Im not too sure. The bulbs you have listed all have a common power but the ground are all separate. Maybe the printed circuit board on the back is bad. Pull the cluster and see if it looks fine. Any sings of arching or burns.

As for the clicking dizzy, I have no clue. Ive never heard that before. There isnt anything to make a noise when the car isnt working. Its just full of sensors and the rotor button.

Hope I was any help. Let us know how it goes.
