I posted this in the General forum. The indie shop found that my TCU is waking up, pulling ~.5 amps then going back to sleep. The shop is working to determine if we can simply unplug the TCU. I do not use the car's Bluetooth as it is too old and it is rather irrelevant in a convertible.

I will post an update.

For others with a parasitic battery drain, check our TCU.
