I recently bought a 2013 535i with just under 129,000 miles that is in the shop (BMW dealership service dept.) due to the instrument cluster lights intermittently flickering. The technician stated that he can't duplicate the issue. He also said that the alternator is good, but he thinks the battery is the original and recommends that it be replaced soon. After looking over the paperwork that the previous owner gave me, the same shop had replaced and registered the battery back in March 2017, so going on 8 years. They charge $656.30 to replace/install/register a new battery. It's easy to install a battery, but can I use the BimmerLink (by SG Software GmbH & Co. KG) iPhone app or a BMW OBD Scanner (e.g., Foxwell NT510 Elite) to register the battery myself, or is it necessary to have them register the battery? TIA!
