I watched some Youtube videos of guys brake torquing the B9. Unlike the DSG where it is in neutral until you let off the brake, the RPMs go up and they have to stand on the brake pedal to keep the car from creeping forward. That has to put a lot of strain (and heat) on the torque converter. But, Like GoCougs, they say that they use it on a regular basis and none mention any damage. Maybe the ZF or TCU has enough smarts to not allow you to overheat it.
I'll have to try it at least once, and (unfortunately) there aren't that many drag race opportunities where I'd really need to use it, so once in a great while it probably can't hurt the ZF. I had a BMW M6 or M7 next to me at a light yesterday, but he wouldn't race. I think they are seriously fast, so he probably thought I wasn't worth bothering with.
I dug thru the manuals again, it isn't there. Did they change something between the B9 and my B9.5?
