From a cold start I'm trying to log it (capture into a graph, or csv file) of the glow plug running, but by the time ive turned the key into the ON position, and load the measuring block the glow plugs would have cycled on/off already (it's like 2.5 seconds).

That is a question for the design team that built your car !! A diagnostic tool has no control over that !!
So your saying VCDS cannot record the state of the glow plug when the relay was given the command for voltage...then what is the "Pre-Glow Period" that I showed an example of in my prior post for?
VCDS can only record what your ECU is willing to report, and your ECU can't "talk" until the ignition is on.
The "glow period" Which is an ECU Output, will be calculated at each Ignition on Event by the ECU based on the control strategy written in the ECU of your German Car - Work of the Devil I say !!
