I am getting bulb warning lights on my E46 325i Sedan (Facelift)
The problem started about a year ago (its the common grounding issue) The problem went away itself but has now just come back and my entire left side tail light is not working.
I've pinched a couple of pictures from an earlier thread to show my issue, its identical, and also my brown wire has lost about 3 inches of its plastic cover and is exposed wire.
Q1) If I jiggle the wires about, I get a sort of spark coming off them (ignition is off). Is this dangerous? I read you do not need to disconnect the battery to do the fix.
Q2) I know the proper fix would be to replace both bulb carriers and a beefier ground wire etc.. but as a temporary fix to get my lights working, can I just splice into the existing brown wire and connect to the tab as shown below?
Or should I completely remove the brown wire from the black plug and connect this directly to the ground tab.
Appreciate the help.
