chasing of e70 battery drain in progress

[Ron07x5]

Ok I am seeing a battery drain when the x5 should be sleeping.
The alternator is charging but when you stop the car is discharges the battery at ~3 to ~5amps so overnight you have a 50%+ discharged battery. Sometimes the problem happens and sometimes not, I haven't worked out why.
I have removed all the CDs so the player can't be doing it, I have deleted all Bluetooth phone connections.

I have a TPM malfunction that I can't reset, and perhaps that is keeping the car awake and then it drains battery? Right now I am wondering if I need to disconnect the battery to get the car to give up on the attempted TPM reset which the display continues to say it is doing?

IF I do not resolve this soon, I am going to order a low voltage mini amp clamp and go searching, If I need to also get a logging dvm with that I will. Seems these cars like to drain batteries and I must tame the devil.
