So, downloaded and played with BTool for a couple of days. It's now called bimmer-tool. Connects to my Bluetooth OBD module easily & quickly, solid connection afterwards.

Clean tabular display, not the cool gauges like Torque. Still no oil pressure, only one EGT (?), surprisingly no NOx parameters available. But it's got loads of others that Torque doesn't have; battery voltage, current, battery health, glow plug controller output, DPF status, regen start/stop, and others. Good value for $14.99.

Interestingly, I now see that the glow plug controller is way more active than just at the moment of starting the engine. It stays on (varying 100-300W) up to ~1300rpm for the first 5-6 minutes. Comes on during the DPF regen cycle also. Going to have to do some reading on its operation.
