Result. Gas tank vacuum pump fails oddly one week later. $100. Then passenger airbag/seat tensioner warning comes on and dealer fixes this via battery cable which he says I didn't tighten or attach properly. $150. Tech says there are tons of voltage related error codes and need a BMW battery and registration. So one year later ( I'm in it to win it), the same battery and no problems knock on wood.
Next time. I'd buck up for a better battery. Think their called amg, mat glass European spec. But same plan.

Go with the aftermarket battery. Here's the truth about the battery registration. It basically tells the alternator the amp it should charge the battery at. Apparently it's different from when the battery is new vs. old. I got mine from Sears and put it in myself for $124. No problems whatsoever in the 9 months since i put it in WITHOUT coding. It comes with a 36 month replacement warranty and 72 month conditional warranty. I figure if it dies again in 3 years, I'd have a new battery which is a win. If it dies after 5 years, i'd be happy to spend another $124 for a new one vs. $550 with coding which is a win. A WIN WIN in my book. 
As you say, it will charge at a different amp. I'm not worried about damage to the battery since it can be replaced. I wonder if it will damage the alternator and/or other parts in the car. I guess after 9 months and no problems... it's all good.

Can someone register my battery for me. Someone close to Irvine or Fullerton, CA?
