Awesome post, thanks a million. I replaced the battery in my 2006 330i tonight. I went with the Bosch 94R from Pep Boys. almost an exact match to the OEM. just an inch or so shorter but actually made it easier to reinstall. 730CCA and 80A. Now I just need to reset the battery sensor.
Anyone in San Diego area that has a Bav Tech tool, or used a non-dealer shop for this?
