Is there a way to activate the coolant glow plugs via vagcom or check the function to see if they are working with vagcom?????

IIRC output tests will have one step for low power relay and one step for high power relay. I haven't worked on an ALH in so long that I forgot the standardized numbers for them :)

Where would the output test for the coolant glows plug be located? I just want to hear if the relays are clicking on and off.

As this is an old, relative low-tech ECU, you'll have to step through the pre-programmed (in the ECU's firmware) sequence of tests to find out what's in it.
