Mine is a 2006, and this is where it's located. It's looking through the gap between the steering wheel cowling and the lower dash panel above the foot rest/brake pedal on a DSG.
The bracket is clipped onto a bar further along to the right. If you unclip that it will pivot downwards at the point shown. There is a clip each side holding the controller to the bracket which need to be squeezed together to release. The red plug is the gateway connector.
It's not the easiest thing to get a photo of without removing bits of trim but hopefully it will help you out.
I'll try and get a better photo if needed when it stops raining.
