Re: Diagnostic tools

The OBDII port is only connected to the engine module. You need to use the round 20-pin connector to get to anything else. The engine module is also connected to it, so you might as well just use that. The only time the OBDII port might be useful is to run diagnostics/monitoring whilst driving. Chee...

Re: Remote Locking.

Yes, that is correct. If the indicators flash on unlock, it means the alarm has been triggered since it was locked.

Re: Alarm issue with starting my Z3

The muted alarm sound is what you get on the early alarms with a separate fob when the power is disconnected and and the siren runs on its backup battery.

Complete loss of power could be many things, but I am thinking possibly a stuck starter motor.

The heater in the Z3 is an air-blender, so on anything but full heat it will blow colder when the water flow through the heater matrix decreases at idle.
