There was also some discussion that there was a diferrence between model years, that might be what you are experiencing.
As far as entering "dyno mode"......either have your ECU hacked or find someone with the Mercedes "STAR" software and breakout box and it's possible.
I just threw this video in for fun......it's a no fuses and disabled yaw sensor run from behind a Dodge dealership.

I have an '05 XF. When sitting on the line and reving the engine up the limiter kicks in at about 4200 RPMs and prevents going any higher. I was wondering if there is a way to do away with this. I'll have to view your video tomorrow at Starbucks since the Academy censors YouTube from us
. I thought pulling fuses 17 and 18 disabled the yaw sensor in addition to the traction control system?
