I did. I used a thermal thermometer pointed right at the fill plug. Past experience shows this is pretty accurate. The fluid overflowing was between "lukewarm" and "warm". I think you can use Bimmer-Link to check temps as well. I got the fluid up to around 42C and then put in the smaller secondary fill plug.
Interesting thing to note: Volvo calls for this same transmission (TG-81SC) to have the final level set at 50-60C. VW calls for the fluid to be 35-45C. This makes me thing that 1) fluid level is less critical than on some other transmissions and 2) shoot for the upper bound of 45C.
Working in a 20C garage, the fluid got up to this level after idling for 7-10 minutes.
