Any time I or someone else has done any welding on my 911, we remove the DME completely from the car to be safe.

So that got me thinking - what if you had to weld on a modern car like my E90. NFW you can remove the electronics like you can in my 911. Any one done this? No big deal or is there something special you need to do before hooking the car up to the welder?

I almost had to resort to the old "weld a nut to the transmission fill plug" because I'm a f**king gorilla and stripped the 8mm hex out. I got the fill plug off with an air chisel, but it got me thinking about the welding issue.
