Where did you source the battery? I'm in the same boat as well... did you end up having the battery synched?It's my understanding and recent experience that simply dropping in a new battery even if it's the same spec won't work for very long. After finding out my battery was on the out and causing random issues I called the dealer for a quote - yeah, right...how much??? Long story short, I sourced the same battery and put it in myself. The only issue is it wouldn't hold a charge and unless I had it sitting on a charger daily.
Solution - the battery had to be synched to the car.
Exactly what I did. :15:I did this last year and just ran the numbers again on their web site. Advance Auto carries the H8-AGM which fits our cars and it's 900cca. They are 189 on line and type code HUGE50 at check out and it takes 50.00 off. There is an 18.00 core that is removed when you bring your battery in. It comes out to 139.00. Then used Rheingold to register battery which takes 2 minutes.
He's correct that if you change from lead acid to AGM then the car has to be reprogramed to the AGM and told what amp the battery is. That's not to be confused with reregistering the battery which is also done when you change the battery of the same type, AGM to AGM. I would go with the AGM if it was me since these cars require a lot of battery. So yours would have to be reprogramed and reregistered.Just spoke with a friend in the parts dept. at BMW of Manhattan about the the battery issue.
My M5 is an early model build MY2006 and I have the white battery (non-AGM). The battery finally kicked a few days ago. He said BMW no longer services the white battery and that I would have to switch to an AGM black battery which DOES require programing.
Luckily I can get a discount on the battery from the dealership, but does the $150 programing fee make sense? Do I really need to switch to an AGM battery or can I just go to Autozone and pick up a replacement non-AGM battery? HELP!!
I think that's the definitive answer. Thanks, as I'll archive in case it ever comes up again.He's correct that if you change from lead acid to AGM then the car has to be reprogramed to the AGM and told what amp the battery is.

Somebody who owns a computer with Rheingold, INPA/EDIABAS on it and the proper OBD cable for the car. (K-line x 2 version for <3/2007 build dates and DCAN version for newer cars).Thanks for all the replies guys. I was at the stealership today getting some oil and asked about the battery:
Battery ranged from like $259 to $329 (3 options)
Service to install/register $120
What all is needed to register a new battery? As the autozone one for $13x.00 seems like the logical route to go as long as I can register it..
