Unexpectedly, this morning my BMW's battery was kaput. Fun stuff.

And yes, in a BMW (E90 at least), replacing a battery takes a little bit of wrenching.

Thankfully there were two guys working construction in my neighbor's house to help me push my car out of the way so my wife could take her car and take me to buy a new battery. Two hours later, I'm finally at work. Fun stuff.

Now I just have to go get it registered so my car knows that there is a new battery. Dealershipt charges $200, I'm sure a shop can do it for less, and I might be able to buy an OBDII tool and do it myself. Any BMW owners have any experience with this?

Thanks a LOT, BMW.
