Yes, an electrician could check that easily. I am not sure on this particular engine if it is connected to on board diagnostics though.

If you have a tester, you can check yourself.

I am not familiar with your engine, but normally glowplugs stick out the top of the head. In the morning with the key off, hook up the tester to the glowplug leads and have an assistant turn key to pre-ignition and check for 12v to the plugs.

If you have 12v to the glowplug leads then they are getting power, you could start pulling the glow plugs and apply 12v and see if they heat up.

No power to glowplug lines and you will have to trace back. It could be the the glow plug relay/control module, not sure what BMW uses to control the pre-ignition system.
