Like physically what happens when you dont get a OEM BMW battery and have it "coded".
Excuse my ignorance but I think all of us still have this question.
Just trying to figure out what the registering/coding does.
Thats what I thought too. My guess is as good as yours. I do recall the mechanic saying that unlike the e36's and e46's, the e9x's are equipped with what is called a "smart pack" which is a plastic box with a bunch of wires in it that attaches to the battery. This is what primarily failed. Anyone familiar with this part?
