Took Avant 4 unit and put back in the OEM unit to see if that would activate anything.... it did not.
Took the car to a trusted audio specialist and they could not find anything wrong...

Safe to assume that during the install process something could have shorted and fried something?
Just so weird that aside from the cluster acting up, the one halo went out and the other is extremely dim.
Now I am considering buying a cluster off Ebay and going that route. I ordered some weislicht halo bulbs as I was planning to use the iBus app to run them as DRL's so I will put those in and see if they magically work.
Fingers crossed.
