Battery? Or something else...
This morning I had a noticeably slow turn-over on my 04 545i. I partly chalked it up to an overnight drop in temperature, but when I started it an hour later at the gym it was still sluggish.
After work, same thing, but it started so I drove home and parked in the driveway. Just now I went to move it into the garage, and I get Christmas tree lights on the dash and no hint of anything turning over.
My initial reaction was that it has to be the battery. The indicator appears black (but honestly I've never looked at it closely so I'm not sure how bright the yellow or green are).
I will jump it to see if that does the trick and then idle it for a while. If that doesn't work, should I assume it's the starter or maybe the alternator? I imagine the clutch/ignition relay that can fail would be an all or nothing type failure and wouldn't have warning signs.
Closest dealership wants $450 to replace and register....

Date code is 17 06 on the battery, so that's almost 7 years, not bad. More evidence that it's the culprit.

Funny conversation you are having with yourself here. I think you hit it though, the battery would be my choice. Go to autozone and get the gold with a 7 yr warranty. This is what I did and it works perfect. Make sure the cranking ams are the same. This was exact to mine. Their system will direct you to another battery but ask for one with what you have.

I did mine myself or I think I did... It was so quick I'm not really sure it happened. Anyway, I'm not worrying about it because if the bat goes ill just exchange it out under warranty. So far over a year and no signs of any issues. If you can locate an Indy then go for that. Otherwise just leave it. That was the main reason I was saying get the exact CA,CCA. If you throw something else in there you may have to get it programmed and registered. Some here have done either so you will get lots of feedback for either way.

replacing a battery should be as simple and taking the old one out and puttint the new on in and hook it up to the leads..
however is there any way to do this without having to reset the sunroof? ie, anything you can put from one terminal to the new one so you dont break the circuit?
i replaced a battery in my e39 and the sunroof has never worked right since. (timing, reinitializing didnt work)

You can get a battery from places like AutoZone, Advanced Auto Parts etc.. and it will save you a lot of money from going to the stealer. You can get a shop to register the battery to the car, make sure you get the battery registered it tells the car you have a new battery so the car adjusts its charging.

im due for a battery as well, can you go a little further in depth in the programming and registration aspect, im slightly lost.
