Battery Issue
In case anyone experiences this, I had a warning come up regarding a "battery charging failure." The X7 has approximately 1200 miles. A message appeared in the iDrive system and attempted to auto-schedule a service appointment. I took it to the dealership and needed a new battery.
As an FYI, BMW has a backlog for replacement batteries so really great dealership team took one out of another X7 while they wait for batteries to ship from BMW. Apparently, this was the Lithium Ion battery, not the main starting battery--the AGM battery. |

I thought X7 just had the Lead Acid AGM 12V battery? |

Doesn't say Lithium Ion battery. What does the 2nd battery do? Where is it located and is it Lithim or Lead acid AGM? |

The lithium ion battery is used to power all the auxiliary equipment like Navigation, iDrive and other auxiliary equipment. |

Car actually has 3 batteries according to my dealership. One of which has a recall.
... clearly I got it repaired already. Don't know where the batteries are located. |

Interesting... According to the diagrams and info I could find there are only two: One in the trunk area and the smaller one in the engine compartment on the passenger side by the firewall. I did find info about a larger 60 Ah battery in the engine compartment. But it was linked to a unique option package and seemed to replace the smaller 10 Ah one.

S2VS: Executive Drive Pro (or just 2VS). Based on the video, it sounds like Active Comfort Drive w/Road Preview which only comes as part of the Dynamic Handling Package option on the X7. If you have the DHP option, you can use a VIN decoder to verify (I don't have the DHP option).
