The constant beeping noise did not stop the sun/moon roof is completely closed it appears to be coming from the dash on the drivers side and beeping doesn't stop

Sounds like the ABS. Pop the hood see if it's coming from the firewall where the computer is.

ok theres a code, lets start with that... Swap the coil on cylinder 6 with whichever, clear the code and see if the code follows where you swapped the coil. While you're in there, check the wires and the plug itself for damage.

I can think of why that would cause a buzzing/beep though.
