How to fix the electrical grounding issue on a BMW E46 3 Series.
Here I have a 330ci but this fix applies for any 3 series from 2001-2005. There are small variations on tail light housing base on location and year so check your car first.
This is a common issue with these cars and the method above fixes the issue with minimal parts and tools required.
