2.) I went and got a multimeter today for this one. The reading in V at the jumpstart terminals was 6.5 Volts. I was expecting this to be around 12, isn't that what it is supposed to be?
2a.) The Remote key did unlock and lock the doors a few days ago, but today it is no longer locking or unlocking the doors. The light does not come on inside the cab anymore.
3.) No, today it did not lock in place. I think my battery is dead. [QUITE, but a charger will "Revive It"]
... what do you think I should do next?
NEXT: Battery Charger, such as one of these:
https://www.amazon.com/ABLY-Automoti...s%2C92&sr=8-19
https://www.amazon.com/AmazonBasics-...2s9dHJ1ZQ&th=1
https://www.harborfreight.com/21050a...attery+charger

Charge battery at Jumpstart Terminals under hood. If outside temp is at/BELOW freezing, remove battery from car and bring inside to charge, as further damage may occur if left outdoors in freezing temps. When voltage measured at Jumpstart Terminals is > 12.0V, 30 minutes after disconnecting charger, then perform tests again.

Please let us know what you find in those tests, and we'll suggest Next Steps. You MAY have a bad Alternator or some "Parasitic Draw" which is draining battery. You have plenty of auto maintenance experience. Just need to add some "Electrical System Basics" to your toolbox.

As for Diagnostic Software, See the attached pdf's:
1) "E9x References, 220216 Revision", which contains links to downloads for INPA & ISTA. I would simply begin by downloading E89 Datens & BMW Standard Tools (INPA) from the MEGA sites linked on the BimmerGeeks Downloads page. The $50 BG K+DCAN Cable is also reliable.
2) "INPA Tutorial Quickstart" explains HOW to setup your cable and get started with "INPA Functional Jobs". It also contains example screens to show you what the Module Identification screen, and the Error Memory, All Modules screen look like. It also explains other INPA functions such as reading Fault Code Definitions & Freeze Frame Data, Viewing Live Data, and performing "Activations".

Please let us know if any questions downloading or installing INPA/E89 Datens.
