Hey guys, I have a 99 328i and I need to change the battery in it. Normally I'd let the guys at the store do it for me, but since the car is dead in my garage, that's not an option. I tried searching thru the forums to see if I could find some instructions but didn't really see anything. I know the battery is in the trunk but is it a pretty straight forward way or replacing the battery?
Actually it was pretty simple until I noticed all of the corrosion on the negative post and cable. I've tried everything from coke, Liquid Wrench, WD40 and nothing I've tried has made the cable budge from the post. I was able take the washer and bolt off of it but that's it, but at this point I'm stuck. Right now i'm considering just removing the entire negative battery cable from the car along with the dead battery and just purchasing a new negative cable. Hopefully that wont run me that much money. Also, I'll have to figure out a way to get that tightly screwed bolt unscrewed from the chassis so that I can even take the cable off...
Did you try pulling the bolt out of the clamp and working it open with a slot screwdriver or something of the sort? It might be enough to dislodge it. Then you could clean it up after getting it off the battery and re-use it

Yeah, this morning I ended up disconnecting the battery cable from the car and now I just have the dead battery with the neg. cable attached to it. I've tried everything possible to get it off of the post and it seems like it's not going to move without me actually breaking the casing of the battery. So from this point I'm searching for another neg. cable. I was wondering if I can just go to an auto parts shop and buy one, I know it's not going to be the same as the OEM one, but would it matter?
